i think so
No. Baking soda is a substance that has physical and chemical properties.
Nearly, a physical change creates a substance and this is reversible. For example, ice-water. Water-steam. These are all reversible. A chemical change is irreversible. For example, baking a cake; you cannot get the original ingredients back again.
pretty sure its a chemical change.
For example by boiling or baking.
Yes it is
It depends on the chemical reaction. For example when you burn something it is a chemical reaction, but that is way different than if you mix baking soda and vinegar which is also a chemical reaction. It changes the matter into a different chemical matter make up of that substance.
adding heat to a substance might produce a new gas, resulting in a chemical change for example when baking powder is heated it produces carbon dioxide gas which is needed to make a cake fluffy and light.
When baking soda and vinegar are mixed,a chemical reaction occurs.A new substance is made.The new substance is carbon dioxide.
a burning candle, or something that's baking...
Baking is a chemical reaction for a few reasons. First off, heat is being applied to change a substance (cake mix / batter) into another substance (baked cake). Reactions occur such as water and moisture turning to steam as a result of the heat, and ingredients like water and baking soda / powder react to create a fluffy cake.
No vinegar is an acid. That's why it reacts with the basic substance baking powder. But it is a mild acid. So it won't hurt you ;)
ammonia, milk, baking soda are just a few :) A basic substance has a pH greater than 7. An acidic substance has a pH less than 7. A substance with a pH of 7 is neutral.
