Answer:
Some bacteria like <em><u>rhizobium</u></em> and <u><em>blue green algae</em></u> are able to fix nitrogen gas from the atmosphere to enrich the soil with nitrogen compounds and increase its fertility. The nitrogen-fixing bacteria and blue green algae are called <u><em>biological nitrogen fixers.</em></u>
Porque la temperatura de la agua es neutral
Answer:
The answer to your question is 2 molecules
Explanation:
Unbalanced chemical reaction
H₂(g) + N₂(g) ⇒ NH₃ (g)
Reactants Elements Products
2 H 3
2 N 1
Balanced chemical reaction
3H₂(g) + N₂(g) ⇒ 2NH₃ (g)
Reactants Elements Products
6 H 6
2 N 2
From the balanced chemical reaction we conclude that when 3 molecules of hydrogen react with one molecule of nitrogen, 2 molecules of ammonia will be formed.
The total atomic number must be the same on each side. The total mass number must be the same on both side.
<span>On the RHS, for the mass number, we have 257 + 4 = 261 (the 4 comes from the 4 neutrons). That means the mass number of the missing piece on the LHS is 261 - 247 = 14. </span>
<span>One the RHS, for the atomic number we have a total of 104 since the 4 neutrons are all neutral. On the LHS, we have this: 104 - 98 = 6. </span>
<span>The missing piece is a nucleus of carbon 14. Done in your style, it is 14/6C</span>
