Answer:

In thermolysis, water molecules split into their atomic components hydrogen and oxygen. For example, at 2200 °C about three percent of all H2O are dissociated into various combinations of hydrogen and oxygen atoms, mostly H, H2, O, O2, and OH.

Answer with explanation and you’ll get brain list
Gwar [14]

Answer:

Option D.

Explanation:

  • 6H₂ + P₄ → 4PH₃

First we convert the given reactant masses into moles, using their respective molar masses:

  • 4.00 g H₂ ÷ 2 g/mol = 2 mol H₂
  • 6.20 g P₄ ÷ 124 g/mol = 0.05 mol P₄

0.05 moles of P₄ would react completely with (6*0.05) 0.3 moles of H₂. There are more H₂ moles than required, meaning H₂ is in excess and P₄ is the limiting reactant.

Now we<u> calculate how many PH₃ moles could be formed</u>, using the <em>number of moles of the limiting reactant</em>:

  • 0.05 mol P₄ * \frac{4molPH_3}{1molP_4} = 0.2 mol PH₃

Finally we <u>convert 0.2 mol PH₃ into grams</u>, using its <em>molar mass</em>:

  • 0.2 mol PH₃ * 34 g/mol = 6.8 g

So the correct answer is option D.
