<u>Answer:</u> The volume of H_2SO_4 comes out to be 10.2625 mL.

<u>Explanation:</u>

To calculate the concentration of acid, we use the equation given by neutralization reaction:

n_1M_1V_1=n_2M_2V_2

where,

n_1,M_1\text{ and }V_1 are the n-factor, molarity and volume of acid which is H_2SO_4

n_2,M_2\text{ and }V_2 are the n-factor, molarity and volume of base which is KOH.

We are given:

n_1=2\\M_1=0.100M\\V_1=?mL\\n_2=1\\M_2=0.0821M\\V_2=25mL

Putting values in above equation, we get:

2\times 0.100\times V_1=1\times 0.0821\times 25\\\\V_1=10.2625mL

Hence, the volume of H_2SO_4 comes out to be 10.2625 mL.

A particular voltaic cell operates with the reaction: Zn(s)+Cl2(g)---&gt;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
