Explanation:
Order of a reaction is not always whole number. It can be zero, or fractional .
Answer:
The coefficient is 1
Explanation:
CaO(s) + CO2(g) -> CaCO3(s)
In the balanced equation, the coefficient for CaO is 1
The coefficient represents the number of moles of a compound in the stoichiometry of the reaction
Metallic ion because the metallic ions will enter an exited state and release photons energy, in the form of light, as they return to their ground state.
