A stable pH is essential for the growth of plants in soil. There are three main important things for the plant growth: (1) nutrients in soil, (2) water, and (3) carbon dioxide. A process called acid leaching may be used to remove the heavy metals which impede the growth of plants.
Hydropower is electricity generated by harnessing the energy of moving water. This kind or energy provides almost one fifth of the world's electricity.

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>
