Answer:
The balanced chemical equation will be "
".
Explanation:
The given equation is:

<u>Step 1:</u>
<u></u>
...(equation 1)
<u>Step 2:</u>
<u></u>
...(equation 2)
On adding "equation 1" and "equation 2", we get
⇒ 
⇒ 
The second step:
⇒ 
The theory of evolution was proposed by Darwin.
2NH₃(g) + CO₂(g) → CO(NH₂)₂(s) + H₂O(l)
is the balanced equation for the synthesis of urea.
Answer:
0.719 moles of NH₃
Explanation:
Molar mass of ammonia 17 g/mol
Mass of amonia = 12.23 g
Mass / Molar mass = Moles
12.23 g / 17 g/mol = 0.719 moles
