Answer:
<em>The grams of hydrogen gas that are released is 0.343 gram</em>
Explanation:
<em>Given that:</em>
<em>2 Na + 2h₂0 ⇒ 2Na0H +N₂</em>
<em>Molecules of Na = 7.9/2.3 = 0.343 mol Na</em>
<em>Now,</em>
<em>2 molecules of Na produces one mole h₂</em>
<em>0.343 mol of Na produce 0.343/2 = 0.1717 mol h₂</em>
<em>h2 = molecules * mw (molecular weight) =0.1717 * 2 =0.343 grams</em>
<em>Therefore the grams of hydrogen gas released is = 0.343 grams</em>

Answer:
B. the rate of the forward reaction equals the rate of the reverse reaction.
Explanation:
Equilibrium -
In a chemical reaction , a point or stage is reached , where the rate of forward reaction , becomes equal to the rate of reverse reaction , is referred to as the stage of equilibrium .
In this very stage the concentration on the reactant as well as product side remains constant .
Hence , from the given information of the question ,
The correct option is b.
