yeah it turns pink. WHY?????
it turns a nice shade of gross
The difference between chemical and physical changes is that chemical change is when a new substance is formed, and the reaction is irreversible. So as salt and vinegar do not react, it is indeed a physical change.
It is a chemical reaction and this is the correct way to spell penny!
When an egg is soaked in vinegar the vinegar reacts with the calcium carbonate of the shell by breaking it down into its simplest forms. (Calcium and carbon dioxide.) Therefore causing a chemical change.
Milk of magnesia does not act as a good buffer because the level of ph doesn't change rapidly. The ph needs to change for anything, acid or base.
This reaction is exothermic.
This is a description of the reaction between the acetic acid, which is the "active ingredient" in vinegar, and baking soda, which is sodium bicarbonate. This double replacement reaction is covered in another question on WikiAnswers.
Chemical change
No, because it just change to liquid
A good example would be a reaction between vinegar and Baking soda. The 2 react to form a gas.
because it is change in composition.
Yes, when you add an acid, like vinegar, to milk a chemical reaction occurs. The acid causes milk to curdle. In fact, by adding vinegar to milk you can make cheese! http://www.wikihow.com/Make-Cheese-at-Home
This is a physical change because any reaction occur.
When you combine them it is a chemical reaction (change) yes, but them combined in a solution is a physical change.
The vinegar-baking soda reaction is a chemical change.
Yes, it is a chemical reaction.
The change in entropy between products and reactants in a reaction
It is true that a chemical reaction causes a chemical change. An example of this can be seen by adding baking soda to vinegar.
