You kind of need to show more, but the independent variable would be something that you are changing to then measure the reaction, like the time left in for example.
Baking soda has a ph of 9. any # that has less than 7 as a ph is acid, any number that has a ph of 7 is neutral, and any number with a ph greater than seven is a base. so baking soda is not an acid but a base.
Answer:
A decompositon reaction is a reaction that takes place when one reactant breaks down into two or more simpler substances. The decomposition reaction can be represented by the general equation: AB → A + B. Most of the decomposition reactions require an input of energy in the form of heat, light or electricity
