How is chromatography used in everyday life?
Petroleum is used in different forms to propel almost all vehicles, - cars, trucks, trains, ships and aircraft all run on some sort of petroleum. Oils, lubricants for machine…s and you skin(vasoline), some household product and even make-ups have petroleum based/by products. Asphalt/tar and some plastics.
Every day we neutralize things inside and outside of our bodies without even knowing. When we suffer acidity we take milk of magnesia. Even your body alone neutralizes, diges…tion is the best example of acid- base neutralization. However, even when an ant stings the skin and baking soda is applied on the skin for relief, neutralization takes place. Ant sting is acidic and baking soda is basic. Wasp stings on the other hand are basic and vinegar is used for relief on wasp sting, we are still neutralizing. In baking, Use of baking soda in cooking may be for the leavening effect (release of CO2) but it needs a neutralizing reaction to release the CO2. The list is endless.
well, beryllium is not used in everyday life much. but there are uses where you use it in daily life. you can use beryllium in x-rays. although x-rays are not everyday life th…ings so beryllium is not used in everyday life very much. why? because this element is toxic. you would work with this if you make computers and work with gyroscopes because computers and gyroscopes have beryllium in them. if you work in a nuclear station you would work with it because it has a high melting point. so all I have to say is that beryllium doesn't have a everyday life unless you are a someone who works with beryllium! btw im 11 years old soo dont think this would be wrong.
Suppose you have a coupon for $5 off, followed by a 25% discount. You would use PEMDAS to evaluate .75(x - 5) (parentheses followed by multiplication). I am a tournament Scra…bble player, so I would use PEMDAS while keeping score. Suppose I play QUIXOTE (as a bingo) on a triple word with Q being doubled. Then my score for the word would be 3(2(10) + 1 + 1 + 8 + 1 + 1 + 1) + 50 Use the order of operations here: = 3(33) + 50 = 149 points.
It's most commonly used in photography in Xenon flash units as its a noble gas and doesn't react with other chemicals or get used up- when a high voltage is put through the ga…s it emits a bright white light- the charge is stored in a capacitor the quickly dumped through the tube containing the gas in a quick burst - most mobile phones now have this type of flash as well - previously it was done by a high band (high blue colour ,almost white) LED (light emitting diode) most red eye reducing cameras have both -LED for anti red eye then a Xenon flash for the picture! Of course its used in neon signs as well! - The effect is related to plasma discharge were the electrons in the voltage field are excited and release photons ( bit of light) which we see. If you have a look at the Periodic table ( the list off elemental chemical (it's in every chemistry book) it will be on the far right side with the other Nobel gases the list runs downwards and includes Argon etc.. all of these do the same thing and light up when a voltage is put through them- but they all give off a different colour- this is what gives you all the different colours in Neon signs!
We use wheels for: Transportation: Cars, Trucks, motorcycles, bicycles, buses, trains, etc.Making heavy machinery mobile: Cranes, loaders, bulldozers, backhoes, etc.Making we…apons mobile: Tanks, canons, multi-tube rocket launchers, etc.To help aircraft take to the sky and land again.Fun: Roller coasters, dodgems, etc.
One example of everyday use of a database is the telephone directory. Another is your own personal address book. You might also refer to the contents page or index of a book…, or use a dictionary to look up the meaning, pronunciation or origin of a word; these are everyday databases, as are encyclopedias. Schools keep a list - a database - of all students attending, and of students attending each individual class, as well as of all staff employed by the school; all employers keep databases of their employees.
It helps clean clothes in the washer. Friction is important in all aspects of life. Friction is a contact force caused by interactions at the molecular level. If friction wa…s not present, any object accelerated on a flat surface would continue to move in that direction infinitely, or until it met an obstruction on that surface. Similarly, without friction, locomotion (moving) would not be possible because we would have no way of establishing contact with any surface. Our feet (or anything, for that matter) would not "grip" any surface, but rather accelerate across it in the direction of the muscle movement. Situations like these do not arise because there is no such thing as a completely frictionless surface. Friction, in terms of how it is used on Earth, can be very helpful in preventing motion. For example, it is the force of friction that allows brake pads to squeeze the rotors of a car's wheel, thus converting the kinetic energy of the moving vehicle into thermal energy, slowing it down.
Length is the same as distance. How far is it to the store? How far is it to Grandma's house? How tall are you? What size of shoe should you buy? How big of a bed do y…ou want? If you are 6'2" tall, how long of a bed should you buy? What diameter of pizza should I buy? How long should I cut a board for the home repair? How long was the kickoff? How long was the fieldgoal? If my average step is about 3 feet, and it is 35 paces between telephone poles, then what is the spacing of the telephone poles?
Pyrite is used for carpeting houses, growing food, bone density, manufacturing sulfur, sulfuric acid, sulfur dioxide, and inexpensive jewelry.

Symmetry is often seen everyday by people of all ages in nature. Symmetry that we see everyday in nature is most often Bilateral Symmetry. This means that the two halves of an… object are exactly mirror images of each other. Symmetry in humans the human face has a line of symmetry in some places, but some faces are more symmetrical than others. The more symmetrical your face the prettier your face will appear. A perfect example of this is supermodels and actresses. Another example of human symmetry is the kidneys, lungs, and the brain. If you draw a line or slice these organs in half, you will have a mirror image of the other. In flowers there are roughly identical petals, sepals, stamens, and leaves. While at the beach there are a wide variety of shells and underwater life with a line of symmetry, an example of this is a crab, a lobster, octopus, and starfish. Crystal G.
when someone asks you the time, you rarely respond with it is eleven twenty three and fourteen seconds, you typically say its eleven twenty five.
To seal your frig door; inside your toaster; in all the motors in your house.
Every time you hand over money to pay for something. You expect the change, so if you hand over a £10 note and bought something for £6 then you subtract 6 from 10 and expect… to get £4 in change.
Getting weevils out of flour. Also helps aerate the flour. Removing contaminants from a process fluid.
