Is anti- acid tablets in water a chemical reaction or physical change?
it is a chemical process due to changes in pH occur, which are held to chemical processes. :)
What are Two main kinds of changes that you can observe when chemical reaction occur?
a precipitate is a solid that forms during a chemical reactions
How does the evolution of gas occur in a chemical reaction give an example?
This is a sign of a chemical reaction.
Would a chemical reaction occur if calcium is added to magnesium chloride?
Any reaction occur.
What comes out of a reaction?

What changes can you observe when cemical reactions occur?
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.
Describe the two types of energy changes that occur in a chemical reaction?
An exothermic reaction and the change between potential and kinetic.
In terms of chemical bond and electrons what kind of changes occur between atoms when substances undergo chemical reaction?

When paper changes from yellow to brown in sunlight what type of change occurred?
A chemical change. Color change is a good indicator of a chemical change.

What two kinds of energy changes can take place during a chemical reaction?
Two types of energy changes that can occur in a chemical reaction are (1) endothermic and (2) exothermic. Endothermic is where energy is added to the system and exothermic is where energy is given off by the system.
