The balanced form of the chemical equation shown is N₂(g) + 3H₂(g) → 2NH3(g) (option A).

<h3>What is a balanced equation?</h3>

A chemical equation is said to be balanced when the number of atoms of each element on both sides of the equation is the same.

According to this question, the chemical equation between nitrogen and hydrogen is given as follows: N₂(g) + H₂(g) → NH3(g)

The balanced form of the chemical equation shown is N₂(g) + 3H₂(g) → 2NH3(g).

Explanation:

The reaction equation will be as follows.

$CO_{2}(aq) + H_{2}O \rightleftharpoons H^{+}(aq) + HCO^{-}_{3}(aq)$

Calculate the amount of $CO_{2}$ dissolved as follows.

$CO_{2}(aq) = K_{CO_{2}} \times P_{CO_{2}}$

It is given that $K_{CO_{2}}$ = 0.032 M/atm and $P_{CO_{2}}$ = $1.9 \times 10^{-4}$ atm.

Hence, $[CO_{2}]$ will be calculated as follows.

$[CO_{2}]$ = $K_{CO_{2}} \times P_{CO_{2}}$

= $0.032 M/atm \times 1.9 \times 10^{-4}atm$

= $0.0608 \times 10^{-4}$

or, = $0.608 \times 10^{-5}$

It is given that $K_{a} = 4.46 \times 10^{-7}$

As, $K_{a} = \frac{[H^{+}]^{2}}{[CO_{2}]}$

$4.46 \times 10^{-7} = \frac{[H^{+}]^{2}}{0.608 \times 10^{-5}}$

$[H^{+}]^{2}$ = $2.71 \times 10^{-12}$

$[H^{+}]$ = $1.64 \times 10^{-6}$

Since, we know that pH = $-log [H^{+}]$

So, pH = $-log (1.64 \times 10^{-6})$

= 5.7

Therefore, we can conclude that pH of water in equilibrium with the atmosphere is 5.7.

Harman [31]

Answer: 2800 g

Explanation:

$CaCO_3(s)\rightarrow CaO(s)+CO_2(g)$

According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number $6.023\times 10^{23}$ of particles.

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

Given mass = 5 kg = 5000 g

$\text{Number of moles}=\frac{5000g}{100g/mol}=50moles$

1 mole of $CaCO_3$ produces = 1 mole of $CaO$

50 moles of $CaCO_3$ produces = $\frac{1}{1}\times 50=50moles$ of $CaO$

Mass of $CaO=moles\times {\text{Molar mass}}=50moles\times 56g/mole=2800g$

2800 g of $CaO$ is produced from 5.0 kg of limestone.
