Answer:

P₄ + 5O₂ → 2P₂O₅

Explanation:

Phosphorus burn in the presence of air and produced diphosphorus pentoxide.

Chemical equation:

P₄ + O₂ → P₂O₅

Balanced chemical equation:

P₄ + 5O₂ → 2P₂O₅

Equation is balanced because there are four phosphorus atoms ans ten oxygen atoms in both side of equation.

Coefficient with reactant and product:

P₄         1

O₂        5

P₂O₅    2

A sample of 4.5 moles of hydrogen is used to react how many grams of nitrogen trihydride will be produced
GaryK [48]

Answer:

51.1 g NH3

The required chemical reaction is given by:

N2 + 3H2 --> 2NH3

4.5 mol H2 × (2 mol NH3/3 mol H2) = 3 mol NH3

molar mass of NH3 is 17.031 g/mol

3 mol NH3 × (17.031 g NH3/1 mol NH3) = 51.1 g NH3

In the balanced equation , CS2 + 3O2 = CO2 + 2SO2 , how many mol of O2 would react with 34.5 mol of CO2?
Arada [10]

<u>Given:</u>

Moles of CS2 (it cannot be CO2 as mentioned in the question, since O2 reacts with CS2 and not CO2) = 34.5 mol

<u>To determine:</u>

Moles of O2 undergoing the reaction

<u>Explanation:</u>

The reaction is-

CS2 + 3O2 → CO2 + 2SO2

Based on the stoichiometry: 3 moles of O2 reacts with 1 mole of CS2

therefore the moles of O2 that would combine with 34.5 moles of CS2 are

= 3 moles O2 * 34.5 moles CS2/1 mole CS2 = 103.5 moles

Ans: Around 104 moles of O2 would react with 34.5 moles of CS2
