Gaseous methane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water . Suppose 9.6 g of methane is
lianna [129]

Answer:

21.6 g

Explanation:

The reaction that takes place is:

  • CH₄ + 2O₂ → CO₂ + 2H₂O

First we<u> convert the given masses of both reactants into moles</u>, using their <em>respective molar masses</em>:

  • 9.6 g CH₄ ÷ 16 g/mol = 0.6 mol CH₄
  • 64.9 g O₂ ÷ 32 g/mol = 2.03 mol O₂

0.6 moles of CH₄ would react completely with (2 * 0.6) 1.2 moles of O₂. As there are more O₂ moles than required, O₂ is the reactant in excess and CH₄ is the limiting reactant.

Now we <u>calculate how many moles of water are produced</u>, using the <em>number of moles of the limiting reactant</em>:

  • 0.6 mol CH₄ * \frac{2molH_2O}{1molCH_4} = 1.2 mol H₂O

Finally we<u> convert 1.2 moles of water into grams</u>, using its <em>molar mass</em>:

  • 1.2 mol * 18 g/mol = 21.6 g

If 6 mol of H, react, how many moles of ammonia will be produced?
PtichkaEL [24]

Moles of Ammonia produced : 4 moles

<h3>Further explanation</h3>

Given

6 mol of H₂

Required

moles of Ammonia

Solution

Reaction

N₂ + 3H₂ → 2NH₃

In chemical equations, the reaction coefficient shows the mole ratio of the reacting compound (reactants and products)

From the equation, mol ratio of H₂ : NH₃ = 3 : 2, so mol NH₃ :

= 2/3 x moles H₂

= 2/3 x 6

= 4 moles
