(5) Calcium metal will react with iodine to produce solid aluminum iodide according to the unbalanced equation: Caco +
Cal2(s). If three moles of
Calcium metal and four moles of iodine, how many moles of Calcium iodide
could be produced in this reaction.

They carry out the exchange of gases as we breathe ( oxygen and carbon dioxide).

Are you going to give an example of the plant or?

The second and last option are the answers

In reversible reaction chemistry equilibrium is attained when the forward and reverse reactions are taking place at the same rate, thus, the concentrations of reactants and products remain the same. a reversible reaction is a chemical reaction where the reactants form products that, in turn, react together to give the reactants back. in irreversible reactions on the other hand, the reactants react to form the products, which cannot revert back into reactants.
