9. In the reaction of sodium hydroxide with chlorine gas, sodium chloride, sodium hypochlorite, and water a
reproduced. If 48.9g of chlorine gas is bubbled into a solution containing 54.2 g NaOH, how many grams
of NaClO can eventually be produced?
2 NaOH +Cl, = NaCl + NaClO + H, O

51.4 g of NaClO will be produced.

Explanation:

To calculate the moles :

According to stoichiometry :

1 moles of require = 2 moles of

Thus 0.69 moles of will require=  of

Thus is the limiting reagent as it limits the formation of product and is the excess reagent.

As 1 mole of give = 1 mole of

Thus 0.69 moles of give =  of

Mass of

Thus 51.4 g of NaClO will be produced

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.
