Answer:
A. Clastic sedimentary rocks
Explanation:
Chemical form = CaCO3
Clastic sedimentary rocks form from the accumulation and lithification of mechanical weathering debris. Examples include: breccia, conglomerate, sandstone, siltstone, and shale.

Answer:
The rate of reaction of a zero-order reaction is 0.0020 mol/L.
Explanation:
The rate expression of the zero order kinetic are :
![R=k[A]^o](https://tex.z-dn.net/?f=R%3Dk%5BA%5D%5Eo)
[A]= initial concentration of reactant
k = rate constant
R = rate of reaction
We have :
Rate constant of the reaction , k = 0.0020 mol/L s

R = 0.0020 mol/L s
The rate of reaction of a zero-order reaction is 0.0020 mol/L.
Answer: Number 2.
Explanation:
It releases massive amounts of radiation
Answer:
The reaction is endothermic
Explanation:
we know that the reactants had to get energy from its surroundings which means that the reaction is endothermic
