When calcium carbonate is heated, it breaks down into calcium oxide and carbon dioxide. CaCO3(s) →CaO(s) + CO2(g)

You heat 2.0 moles CaCO3.

How many moles of carbon dioxide(CO2) will you make?

Question options:

a.) 2 moles CO2

b.) 0.50 moles CO2

c.) 1 mole CO2

d.) 4 moles CO2

explanation:

i think option no d is the correct answer

a polar bond is formed when electrons are shared unevenly between atoms

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
