A particular voltaic cell operates with the reaction: Zn(s)+Cl2(g)--->Zn^2+(aq)+2Cl^-(aq) giving a cell potential of .853 V.
nadya68 [22]

Answer:

The amount of energy liberated will be 49.38 J.

Explanation:

The amount of energy liberated (gibbs free energy) can be calculated using the following equation:

ΔG° = -nFε

n: amount of moles of electrons transfered

F: Faraday's constant

ε: cell potential

20.0 g of Zn is equal to 0.30 mol.

Two electrons are transfered during the reaction.

Therefore, n = 2x0.30 ∴ n = 0.60

ΔG° = - 0.60 x 96.485 x 0.853

ΔG° = 49.38 J

8. How much heat is released when 85.0 g of steam condense to liquid water?
sergeinik [125]

Answer:

199920J

Explanation:

Given parameters:

Mass of steam  = 85g

Unknown:

Heat released when the liquid is condensed  = ?

Solution:

The heat released by the substance is given as;

         H  = mL

H is the heat released

m is the mass

L is the latent heat of steam  = 2352J/g

Heat released  = 85 x 2352  = 199920J

What kind of solution would have a Kb value much greater than 1?
Marta_Voda [28]

Answer:

B. a strongly basic solution

Explanation:

Kb is base dissociation constant, which indicates how completely a base dissociates into its component ions in water. The greater the Kb value, the greater the alkalinity of the solution and vice versa.

Therefore, a solution with a Kb value much greater than 1, indicates a strongly basic solution, while a solution with a Kb value less than 1, indicates a weakly basic solution.
