In the balanced equation, 4ko2 + 2co2 = 2k2co3 + 3o2 which two chemicals have a molar ratio of 3: 4?

Oxygen gas and potassium superoxide have a molar ratio of 3:4.

Explanation:

According to reaction, 4 moles of potassium superoxide reacts with 2 moles of carbon dioxide to give 2 moles of potassium carbonate and 3 moles of oxygen gas.

Mole ratio is defined as ratio of moles of two chemical compounds in a given chemical equation of the reaction.

Moles of potassium superoxide = 4

Moles of carbon dioxide = 2

Moles of potassium carbonate = 2

Moles of oxygen gas = 3

Molar ratio of oxygen to potassium superoxide =

Oxygen gas and potassium superoxide have a molar ratio of 3:4.

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.
