NaCl is table salt so you need 4Na and 4 Cl, So Na₄Cl₄

The reaction equation is:
<span>HBr + H₂SO₄ </span>→ <span>SO₂ + Br₂ + H₂O
An oxidizing agent is a substance that itself becomes reduced and oxidizes the other chemical species in the reaction mixture. A reducing agent is similar, except that it becomes oxidized and reduces the other substance.
In the reaction, the valency of bromine changes from -1 to 0, so it is oxidized, making it the reducing agent. The valency of sulfur changes from +6 to +4, so it is reduced, making it the oxidizing agent.</span>
The number of moles of nitrogen gas is 1.0 mole
<u><em>calculation</em></u>
N2 is a molecule therefore;
1 molecule of N₂ = 2 atoms of N
? molecules= 1.2 x10 ²⁴atoms
<em>by cross multiplication</em>
=[( 1.2 x 10²⁴ atoms x 1 molecule) / 2 atoms] = 6 x 10²³ molecules
According to Avogadro's law 1 mole =6.02 x 10²³ molecules
? moles= 6.0 x 10²³ molecules
<em>by cross multiplication</em>
= [(6.0x 10²³ molecules x 1 mole) / 6.02 x10²³ molecules] = 1.0 mole
