Answer:
A option
Explanation:
Because recatants are in solid form having less enetropy and products are liquid form having more entropy
While other options reactants and products are in same phase gas phase having same entropy
The reaction that would result in increased entropy is the combustion reaction;
KNO3(s)--->K+(aq)+NO3-(aq). Option A
This is further explained below
What is a combustion reaction?Generally, a combustion reaction is simply a combustion process that occurs when a material combines with oxygen gas, producing energy as light and heat.
In conclusion, the chemical reaction KNO3(s)--->K+(aq)+NO3-(aq) is has all properties of a combustion reaction as the solid reactants gives an aq solution.

What types of radiation cause the parent isotope to change into a different element?
Answer:
Beta decay is most common in elements with a high neutron to proton ratio. Gamma decay follows the form: In gamma emission, neither the atomic number or the mass number is changed. A high energy gamma ray is given off when the parent isotope falls into a lower energy state.
