Answer:
2 moles CO2
Explanation:
According to the stoichiometric ratio the mole ratio of CaCO3:CO2 is 1:1
Therefore the moles of CO2 = 2 * (1/1)
= 2 mol CO2
Answer:
D. Grams liquid x mol/g x delta Hfreezing
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to reason that the stoichiometry used to calculate energy released when a mass of liquid freezes, involves the grams of the liquid, the molar mass of the liquid, as given in all the group choices, and the enthalpy of freezing because that is the process whereby a liquid goes solid.
In such a way, we infer that the correct factor would be D. Grams liquid x mol/g x delta Hfreezing which sometimes is the negative of the enthalpy of fusion as they are contrary processes.

You would put it on the flat side because it would be easier to build on flat ground than a steep slope
