A theory fits all three of these descriptions. you can test, predict, and prove or disprove a theory. hope this helps!
Answer:
The study of reaction rates is called Chemical Kinetics.

Answer: A. 1,1,1
Explanation:
The coefficients that will balance the equation; NH4OH(aq) →H2O(l) + NH3(g), is 1, 1, 1, because it proves the total number of atoms of each element on the LHS and RHS of the equation are equal, hence balanced.
LHS RHS
N = 1 1
H = 5 5
O = 1 1
I am not sure about the first question but the temperature has an important role in this situation because as the temp goes up particles moves at a faster speed and spread out every where.
The reaction is exothermic and the product can be clearly indentified .the experement illutrate the difference is reactive between zinc and lead oxide and hence the idea of competition reaction.
