Answer:

D. The reaction will be spontaneous at any temperature.

Explanation:

  • For the reaction to be spontaneous, the free energy change (ΔG) must be negative (< 0).

∵ ΔG = ΔH - TΔS

where, ΔG is the free energy change.

ΔH is the enthalpy change,

ΔS is the entorpy change.

  • Since ΔH is negative and ΔS is positive;

ΔG = (- ve) - T(+ ve) = - ve value.

ΔG will be negative at all temperatures.

<u><em>So, The reaction will be spontaneous at any temperature.</em></u>

The chemical equation shows the production of magnesium chloride.
Norma-Jean [14]

Answer:

1 gram of H2 will be produced from 12 grams of Mg.

Explanation:

According to Stoichiometry, 0.5 moles of Mg are present. 1 mole of Mg produces 1 mole of H2, so 0.5 moles of Mg will produce 0.5 moles of H2. Multiplying molar mass of H2 i.e. 2 gram/mole with 0.5 moles, we can find the mass of H2 in grams which is 1 gram.

I would say you should use or test it once a week to ensure it is working properly in an active laboratory since it is a workplace with significant chemical hazards so it would give peace of mind to know on a quite regular basis that it can be relied on in case of an emergency like an eye flush for example.
