If 10.5 g copper chloride react with 12.4 g aluminum what is the limiting reactant

copper chloride

Explanation:

From the balanced equation. it can be seen that 3 moles of copper chloride reacts with 2 moles of Al.

Thus 0.08 moles of copper chloride reacts with= moles of Al.

Thus copper chloride is the limiting reagent as it limits the formation of product and aluminium is the excess reagent as it is left unused. (0.46-0.05)=0.41 moles are in excess.

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots

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.
