Solution

The skeletal chemical equation is: ${CaC}_{2} (s) + H_{2} O (l) \to Ca {(OH)}_{2} (aq) + C_{2} H_{2} (g)$
Step 1: For balancing a equation the number of elements on both the side should have to be equal. So basically, the number of elements on ( $LHS$ ) should be equal to ( $RHS$ )
Element
Reactant side
Product side
Calcium 1 1
Oxygen 1 2
Carbon 2 2
Hydrogen 2 4
As the number of atoms of Oxygen and Hydrogen are not equal on both the sides.
Step 2: For balancing the chemical equation, just multiply $H_{2} O$ with 2, so that the number of all the elements on $LHS$ be equal to that on the $RHS$ .
Element
Reactant side
Product side
Calcium 1 1
Oxygen 2 2
Carbon 2 2
Hydrogen 4 4
Therefore, the reaction is: ${CaC}_{2} (s) + 2 H_{2} O (l) \to Ca {(OH)}_{2} (aq) + C_{2} H_{2} (g)$

Consider a $70 %$ efficient hydrogen-oxygen cell working under the standard condition at $1$ bar and $298$ K. Its cell reaction is

$H_{2} (g) + \frac{1}{2} O_{2} (g) \to H_{2} O (l)$

The work derived from the cell on the consumption of $1.0 \times 10^{- 3}$ $mol of H_{2} (g)$ is used to compress $1.00 mol$ of a monoatomic ideal gas in a thermally insulated container. What is the change in the temperature (in $K$ ) of the ideal gas?

The standard reduction potentials for the two half-cells are given below

$O_{2} (g) + 4 H^{+} (aq) + 4 e^{-} \to 2 H_{2} O (l)$ , $E^{0}$ = $1.23 V$

$2 H^{+} (aq) + 2 e^{-} \to H_{2} (g)$ , $E^{0}$ = $0.00 V$

Use $F = 96500 {Cmol}^{- 1}$ , $R = 8.314 {Jmol}^{- 1} K^{- 1}$ .
