flour is mixture
Toilet bowl cleaner is a compound mixture. It is made up of various chemical compounds that work together to clean and disinfect the toilet bowl.
A mixture is a combination of two or more substances that retain their own identity. The term homogeneous means that the substances in the mixture are uniformly distributed. (For example, when you are baking a cake, you mix flour, sugar, baking soda, etc., and you put them in a bowl, forming a mixture. Until you stir it up, however, it will not be homogeneous, because the ingredients are not distributed evenly. After you mix it up, it will be a homogeneous mixture with uniform characteristics (cake batter). But at the microscopic level, there are still individual particles of flour, sugar, baking soda, etc. A chemical example of a homogeneous mixture would be a substance that is dissolved in water and uniformly mixed. For example, when you dissolve NaCl (sodium chloride--table salt) in water, it dissolves and (eventually) distributes itself evenly throughout the container. The mixture will contain water molecules, sodium ions (Na+) and chloride ions (Cl-), so it will be a mixture of different substances. But they will be uniformly distributed, so it will be homogeneous.
melting temperature of sugar is 145 C and sulfur is 115 C there is 30 C melting temperature difference so we can melt sulfur easily to separate from sugar. take a bowl and add mixture, set the bowl in oven and set 115 C for one or two minutes. after the time pass. immediately pour the melted sulfur into another bowl with hanger. you will get some elemental sulfur some will solidify do this again at least you gain all elemental sulfur.
It is a homogenous mixture, because it is a mixture of a few different hydrocarbons.Gasoline is a homogeneous mixture.A heterogeneous mixture is one that consists of two or more substances; it is non-uniform and the components of the mixture can be seen. Vegetable soup is an example of this type of mixture.A homogeneous mixture has uniform composition and properties throughout. Salt added to water and stirred until it dissolves is a heterogenous mixture. Air is a homogeneous mixture of gases.Gasoline like most clear liquids is homogenous (of one nature or of a uniform nature). Windex, blood and milk are other examples of homogenous mixtures.Heterogenous mixtures are anything that is not uniform in its composition, some everyday examples are: sand in water, vinegar and oil, and a bowl of oatmeal.
Household bleach is a common household object that contains a chlorine compound called sodium hypochlorite. Pool cleaning products and some water purification tablets may also contain chlorine compounds like calcium hypochlorite. Some disinfectants and toilet bowl cleaners contain chlorinated compounds like trichloroisocyanuric acid.
The substance is a mixture.The component chemicals/ingredients have not reacted with each other.
Toilet bowl cleaner is a compound mixture. It is made up of various chemical compounds that work together to clean and disinfect the toilet bowl.
No, sugar in a bowl is not a pure substance. Sugar is a compound composed of carbon, hydrogen, and oxygen atoms arranged in a specific molecular structure. As a result, sugar in a bowl is a mixture of pure sugar crystals and any impurities present.
solution, I think
1. Make the batter 2. In a medium bowl combine flour, baking powder, and salt; set aside. In a large mixing bowl combine eggs, sugar, and vanilla. 3.Add the flour mixture and milk mixture alternately to the egg mixture, beating on low speed after each addition just until combined. Cover and chill the dough for 2 to 4 hours. Wanna know more? Just go to google and ask how to make a donut.
a cake a cake
1 Have ready a large saucepan containing 8cm (3 inch) of boiling water and a mixing bowl which fits over the pan without touching the water. 2 Break the eggs into the bowl, add sugar and whisk together over the boiling water until the mixture thickens and is lukewarm. Take great care not to overheat the mixture. 3 Remove the bowl and whisk until the mixture is very thick and leaves a trail when beaters are removed. Add the flour, or mixed flour and salt, using a metal spoon. Lightly cut and fold into the mixture. Do this thoroughly but lightly so the air is not expelled.
y u no think about it u mad k12 :D
No, if you want to be sure this isn't a lie, you can mix sugar and water together and leave the mixture out in a bowl for a couple of days then see if there are crystals at the bottom of the bowl. If you did this correctly you should have some crystals there. It's a pretty cool experiment.
A sugar is a pure substance. Sugar is the generic name for many compounds which are all pure substances. Fructose is a sugar. Glucose is a sugar. Lactose is a sugar. Glucose + Fructose --> Sucrose This is a chemical reaction between 2 sugars to make another, more complex sugar. This reaction if I remember correctly eliminates a water molecule as well as producing sucrose. The reaction occurs in certain plants and is done by an enzyme. Mixing fructose and glucose in a bowl will NOT form sucrose. Refer to the wikipedia article on sugar. It shows the molecular structure of sucrose. A substance cannot have a molecular structure if it is a mixture. It is a compound and compounds are pure substances.
One way to separate salt and flour using kitchen equipment is to pour the mixture into a bowl and add water. Stir the mixture until the salt dissolves in the water, leaving the flour particles behind. Then, use a filter or strainer to separate out the saltwater from the flour. Finally, dry out the filtered flour to remove any remaining moisture.
100g butter 100g caster sugar 100g self raising flour 2 medium eggs Preheat your oven at 190 degrees Mix the eggs, flour and sugar together in a bowl. Melt the butter in a microwave, then add to the mixture. Stir until all lumps have gone. Grease a cake tin with a small amount of butter, and pour your mixture in. Put in the oven at 220 degrees for 30 mins. Allow 10mins to cool before eating. Serves 4-5. Enjoy :)
