According to the Gibbs Free Energy equation, some reactions only occur spontaneously at very high temperatures. At high temperatures, the reaction becomes spontaneous if both the entropy as well as the enthalpy are positive.

Changes in Enthalpy, Entropy, as well as Free Energy, Remember that such temperature in the Gibbs free energy equation would be the Kelvin temperature, and as such, it can only be positive. The reaction will constantly be spontaneous at any and all temperatures when H is negative and S is positive, and G's sign is going to be negative.

If a reaction happens without any outside influence, it has been said to as spontaneous. This reaction can release energy and only takes place in the specific circumstances.

Therefore, At high temperatures, the reaction becomes spontaneous if both the entropy as well as the enthalpy are positive.

How many moles of solute are in 53.1 mL of 12.5M HCI?
Deffense [45]
Molarity = moles of solute/volume of solution in liters.

From this relation, we can figure out the number of moles of solute by multiplying the molarity of the solution by the volume in liters.

We have 53.1 mL, or 0.0531 L, of a 12.5 M, or 12.5 mol/L, solution. Multiplying 12.5 mol/L by 0.0531 L, we obtain 0.664 moles. So, in this volume of solution, there are 0.664 moles of solute (HCl).

Use the pull-down boxes to specify states such as (aq) or (s). If a box is not needed leave it blank. If no reaction occurs leav
Andrei [34K]

Answer:

ZnS(s) ⇄ S²⁻(aq) + Zn²⁺(aq)

Explanation:

First, we will write the molecular equation, since it is easier to balance.

2 HBr(aq) + ZnS(s) ⇄ H₂S(aq) + ZnBr₂(aq)

In the full ionic equation we include all ions and molecular species.

2 H⁺(aq) + 2 Br⁻(aq) + ZnS(s) ⇄ 2 H⁺(aq) + S²⁻(aq) + Zn²⁺(aq) + 2 Br⁻(aq)

In the net ionic equation we include only the ions that participate in the reaction and the molecular species.

ZnS(s) ⇄ S²⁻(aq) + Zn²⁺(aq)
