How can you separate each substance when mixed?
Unless a chemical reaction happens, you can usally seperate things by boiling, filtering, or usign a centrifuge. (Sorry, don't know how to translate that). Or, sometimes mixed substances will spontanteously seperate in case a fluid is involved. It really depends on what kind of substances you're talking about.
Used to separate substances from crude oil?
You can separate substances in a crude oil by distillation process. But you have to know what are the boiling points of each of the substance in the crude oil.
Why do you have to balance chemical equations?
You only need to balance a chemical equation if you want to know the proportions (how many of each type of molecules participate in the reaction).You only need to balance a chemical equation if you want to know the proportions (how many of each type of molecules participate in the reaction).You only need to balance a chemical equation if you want to know the proportions (how many of each type of molecules participate in the reaction).You only need to balance a chemical equation if you want to know the proportions (how many of each type of molecules participate in the reaction).
What can you calculate if you know the concentration of a reaction's products and reactants as well as the coefficients of each in the balanced equation?
the equilibrium constant
Does using an emulsifier with vinegar and oil create a chemical reaction?
No, using an emulsifier with vinegar and oil does not create a chemical reaction. An emulsifier helps to create a stable mixture of two immiscible substances, like vinegar and oil, by dispersing the oil droplets throughout the vinegar. This is a physical process, rather than a chemical reaction.
Is Reactants are substances that exist after the reaction has taken place?
see i dont know

Why is it necessary to identify the limiting reactant when you want to know how much product will form in a chemical reaction?
The limiting reactant tells you how much of each reactant is formed. If you use the excess material a false answer for the calculated products will come out.

What happens to the atoms within molecules undergoing a chemical reaction?
In a chemical reaction sometimes old bonds are broken and new bonds are formed.
How do you write esterification equations?
Esterification Reaction: When an alcohol ( mostly primary) alcohol is treated with carboxylic acid in the presence of H2 SO4 sweet smelling compound is formed which is called ester. The reaction is know as esterification reaction.

In a reaction one substance breaks down or decomposes into two or more simpler substances?
The answer is called, decomposition. Just to let you know, I'm in 2nd grade! :) And I know that! :) My sis doesn't even know that, and she's in 5th grade! ;)
If you are trying to decide whether a chemical reaction does or does not take place when two substances are mixed what kind of evidence will you look for?
change of state change of colour fizzing/gas bubbles
How do you know weather curdling of milk is a chemical reaction?
It is never milk again. It will just be churds and whey it will never change back. It changes the substances identity.
When lead nitrate and potassium nitrate solutions are mix why is it changes colour immediately?
the colors will immediately change because it formed a chemical reaction. when two pure substances u know a reaction is going to occur by the temperature changing, change of color (why it turned yellow), produce of gas and produce of precipitation (when it slowly changed into a powder. not all of the have to occur but if u notice that one is that is when a chemical reactions is happening
How do you know which OH group on salicylic acid reacts to form aspirin?
Aspirin is formed in a reaction between salicylic acid and acetic anhydride. In this reaction it is the phenolic alcohol group that reacts to form the aspirin.
