Calculate the maximum amount of useful work that can be obtained and comment on the spontaneity for the reaction at 25C :
harkovskaia [24]

Answer:

1.41 *10^{3}  kJ/mol

Explanation:

First, we find in the tables the ΔH of formation of each compound. As you can see in the (image 1)

Then we solve the ecuation for ΔH°reaction

ΔH°reaction=∑ΔH°f(products)−∑ΔH°f(Reactants)

ΔH°reaction= (-2* 393.5 - 2*285.8) - (52.4 + 0) kJ/mol

ΔH°reaction = -1.41 *10^3  kJ/mol

Joan needs a 0.053-M solution of HCl, but only has access to 2.12-M HCl, a 10-mL graduated pipet, and a 25-mL volumetric flask.
dmitriy555 [2]

Answer:

Joan should measure 0.625 mL of 2,12 M HCl solution to create her desired solution.

Explanation:

Molarity of HCl Joan has access to = M_1=2.12 M

Volume of 2.12 M of HCl Joan use = V_1=?

Molarity of HCl Joan desired = M_2=0.053 M

Volume of 0.053 M of HCl Joan can prepare = V_2=25 mL

M_1V_1=M_2V_2

V_1=\frac{M_2V_2}{M_1}

=\frac{0.053 M\times 25 mL}{2.12 M}=0.625 mL

Joan should measure 0.625 mL of 2,12 M HCl solution to create her desired solution.
