I really don't know and it sucks when i need help and people are giving me false answers.
Smashing the cube into pieces
Explanation:
Smashing the cube into pieces will most likely increase the reaction rate between the manganese oxide and hydrogen peroxide.
The rate of a chemical reaction is a measure of the speed of a chemical reaction.
Some factors that affects the rate of chemical reaction are:
- Nature of the reactants
- Concentration of the reactants or pressure if gases.
- Temperature
- Presence of a catalyst.
- Sunlight(some reactions are light catalyzed)
- The nature of reactants implies the physical state of matter, bond type or surface area exposed of reacting species.
- The surface area exposed is directly proportional to the reaction rate.
- Breaking the cubes into smaller pieces exposes more surface area to the chemical action and the reaction rate increases.

Answer:
Atomic Mass
Explanation:
it is also sometimes below the symbol of the element :)
Of the above options you've given, the only nuclear reaction is fission.
fermentation is when organic matericals go bad and delope mold for exg,
reduction is when atoms of elements have their oxidation states changed (exg rusting)
deposition is when molecules set out in any sort of solution.
