# Tips on Solving Equations With Fractions

Having to handle equations that contain fractions can introduce a whole new level of difficulty for students learning about algebraic manipulation. In many cases, you will be …required to eliminate these fractions before you can proceed with the solution of the equation. Sometimes, you will have to deal with the fractions as they have been provided for you. It is important to be familiar with both the means of handling and eliminating fractions from an equation. This article will explore some of the various best practices that you can adhere to whenever you encounter equations containing fractions in any branch of mathematics, whether it is algebra, calculus, or geometry.Multiplying by a common factor is easily one of the most commonly used techniques that often comes to mind when trying to eliminate fractions in a certain equation. You can simply look at the denominators of the fractions in question. If you find that there is a common factor that all of these denominators have, you can multiply by it in order to eliminate the fraction. Usually, this is helpful when the denominator is a number rather than a variable. When you multiply by a factor in order to eliminate the variable in the denominator, this can result in obtaining incorrect solutions.Factoring can be another effective way to eliminate fractions from equations. Factoring involves taking the greatest common factor within a certain expression and dividing all of the expressions that share this fraction by this factor. The factor is multiplied by the expression in question, which is now enclosed in brackets. By factoring in the expression, you gain a handle on a problem that contains fractions, which would have otherwise been difficult to solve.Multiplying by the conjugate is yet another effective way to eliminate fractions from equations. Usually, you should use this sort of solution only as a last resort. Multiplying by conjugates can sometimes result in a very messy expression that is rendered more unsolvable than the original equation in question. Some hints indicating that you should use the conjugate of a certain expression in order to eliminate a fraction include the presence of roots and squares in either the numerator or denominator of the fraction.If the equation in question contains similar terms, you can gather all of the fractions on one side of the equation and add all of the expressions together. Sometimes, this may result in a whole number such as one. When you do this, this not only eliminates the fraction, but it also renders the expression simpler to solve. However, you should stay on the lookout for individual parts of a whole that are capable of adding up to whole numbers, such as one third and two thirds in the terms of an equation.If the numerous techniques of eliminating fractions failed to provide you with a solution to getting rid of the fractions that are present in your equation, it may simply be that this equation does not have fractions that can be eliminated easily. In such a case, you may have to consider solving the equation with fractions and all. If you have a firm understanding of fractions, their properties, arithmetics, and pre-algebra, this should not pose a challenge to you. However, it may take a bit more time in order to solve the equation correctly than it would by using one of the techniques listed above.There are plenty of things that you can do in order to solve equations that contain fractions more effectively. For example, you can multiply by the conjugate, factor the fractions, try to multiply by a common factor, collect all of the fractions on one side, or resort to solving the problem with its fractions left in the equation. The route that you end up taking ultimately depends on a variety of different factors, such as whether there are expressions that can be multiplied, added, or subtracted by one another, whether there are like terms, and whether there are common factors between the expressions in the equation. Although performing these initial operations may seem time consuming at first, they will save you time and effort later on when you try solving equations with fractions.It is a good idea to brush up on your understanding of pre-algebra before you attempt to solve equations that contain fractions. This is because pre-algebra is an essential subject that needs to be covered in order for you to be able to carry out these operations. (MORE)

# A Guide to Fractional Distillation

What is fractional distillation? Fractional distillation is a part of chemistry as a science, and can be described as the separation of mixtures into their respective parts or… their fractions. This mixture could be made up of chemical compounds, which need to be at their boiling points to separate, for example. In this case, the compounds will need to be heated at a range that allows for one or more fractions of it to vaporize, leaving behind the original components separately. Fractional distillation is a separate branch of distillation and is generally in the practice of using the process of components boiling at a degree lesser than 25 degrees Centigrade from each other, while remaining under pressure of one atmosphere. Since it is a special form of distillation, it is only used when the boiling point is greater than 25 degrees Centigrade; otherwise, the original distillation processes are used.Fractional distillation processes are undergone within controlled conditions and are carried out through standard laboratory equipment, such as glassware. These include glass burners, round-bottomed flasks, condensers, or Bunsen burners. It also uses a fractionating column. In more general terms, a heat source is required that can reach the boiling point of the components involved, as well as safety equipment, such as gloves or coats. A conical flask is used in fractional distillation processes with a round-bottomed flask and a distillation head. Thermometers are also required, as well as boiling chips and general laboratory glassware.To achieve fractional distillation, the mixtures of two or more substances, which are often liquids, are put up on a heating surface with different boiling points for each. A high-pressure steam must be ensured with temperatures able to reach up to 1,112 degrees Fahrenheit. The mixture thus boils and forms vapors, some of the components in the mixture are likely to vaporize. Next, the vapor enters the fractional distillation column, which is thus filled up with trays or hot plates, which have holes or bubble caps. These allow for the vapor to pass through and increase the duration of contact between vapors and the liquids that are thus collected as vapor. The vapor then rises up in the fractional distillation column through the trays and cools off. Through the distillation process the vapors will condense to form a liquid, after which the components can easily be examined and separated.In chemical processes, there is often need to redo the means through which a process has finished to understand the technicalities of it, especially in the education field. This is where fractional distillation processes come in handy. Furthermore, it could be used to obtain and learn the different nature of gases as they mesh together with others, as well as the level of their mixing together. It can be used to separate acetone from water which is a process that is used quite commonly in laboratories. Lastly, it could be used in the process of separating the components that have gone into the manufacturing of crude oil, so that further fuels can be developed.Distillation columns, as used in the fractional process, can depend on what the feed of the desired article is, thus the operation as well as the design will depend on them. The binary components of the feed, as well as the analytical methods like the McCabe-Thiele method, are sometimes used in fractional distillation processes to further enhance one's understanding of the process. There are also specially-designed simulation models in design and operation of fractional distillation.An easy and common way of forming a separation among different mixtures of liquid chemicals, distillation is easily one of the easiest means of understanding how chemical mixtures work. It has been observed in the separation of petroleum, which occurs on oil mines and has profound historical significance. The industrial distillation towers are known to house as many as 10 separate fractional distillation processes occurring simultaneously.Fractional distillation branches out from the much simpler process of plain distillation, but essentially works in the same way. The equipment needed in fractional distillation is slightly more complex. The consequent process requires more steps than would be needed for distillation. However, for extensive chemical compound separation, it is recommended that fractional distillation be used.While some substances are quite volatile and can be easily separated through the complex fractional distillation process, there are others that require particular care. Some could cause problems in separation. Therefore, nonvolatile materials are not commonly used in distillation processes. (MORE)

# Fractionated Palm Oil Explained

Fat is essential to your body and should be balanced with protein and carbohydrates in order to provide you with good nutrition. Brain functioning, healthy skin and other tiss…ues, energy storage, and forming steroids that are then used for many bodily processes are some of the tasks fats have in your body. You could get fats in their purest form, which is a solid fat or oils, or as a part of a food product. Palm oil, or more specifically, fractionated palm oil, is one of such fats that you could find in several products. Here you can learn more about it in order to decide whether this type of fat is the right kind for your body.Palm oil is a type of vegetable oil derived from the oil palm, namely, its fruit. Generally, the oil comes from the African oil palm, but American oil palm could be used as well. Often it may be confused with similar oils, such as coconut oil which comes from a totally different fruit, the coconut. Additionally, palm kernel oil is yet another type of oil, although it is made of the same fruit as palm oil. The kernel is the soft edible part inside the palm fruit and it is contained within its shell. Palm oil is made from the reddish pulp of the fruit, also known as the mesocarp.The process of fractionating refers to heating the oil and then cooling it down again. As a result, the oil is separated into fractions, giving the process its name. Thicker fractions in the oil are more stable and have a higher melting point, so the oil gains some properties that could be later used in the food industry. Fractionating could be used both for palm and palm kernel oil. These oils are already high in saturated fats, which should be consumed in moderation, and the process does not change that amount.Palm oil that has not yet been fractionated is semi-solid at room temperature, so fractionating helps to achieve a better consistency. Thanks to its higher stability, fractionated palm oil is a popular ingredient in chocolates or chocolate coatings. Such chocolates do not melt easily and can have a longer shelf life. Energy bars that come with chocolate icing are also often made with such oil. This oil is rather cheap, so it is used in many processed foods.Like coconut oil, palm oil is high in saturated fats like palmitate and stearate. When it goes through the process of fractionating, the content of saturated fats increases. However, it also contains a high percentage of monounsaturated oleic fatty acid. The oil itself does not contain cholesterol, but consuming it rises both HDL and LDL cholesterol levels. Luckily, the oil is not genetically modified, meaning that it has not been derived from plants that have been manipulated in a certain way.In 2006, research by the USDA Agricultural Research Service and National Institutes of Health showed that the oil could have the same effect as trans fatty acids. This means that excess consumption could lead to cardiovascular disease. As stated earlier, the cholesterol levels in your body also rise if you consume too much palm oil, especially the fractionated type which has a higher percentage of saturated components than the less refined variety. Although the raw dark red palm oil that is widely used in African cuisine could be considered healthy and its carotenes act as antioxidants, the fractionated type does not benefit your health. Fractionated palm oil is slightly healthier than fractionated palm kernel oil, as it contains less saturated fats.Derived from the fruit of palm tree, palm oil is commonly use in African countries. Moreover, it has also become a staple in many processed foods. When it is heated and cooled down, or fractionated, it gains stability and is thus a perfect ingredient for chocolate coatings and other products. However, due to its high staurated fat content, consuming too much if it may harm your health as it has a great impact on your cholesterol levels.Natural unrefined palm oil is dark-red in color because it contains lots of carotenes, such as lycopene, beta-carotene, and alpha-carotene. It also includes tocotrienol, which belongs to the vitamin E family and is good for the skin. Raw palm kernel oil does not include carotenes and is thus not red in color. (MORE)
