Using Dimensional AnalysisExplanation:

Step 1: Define

[RxN - Balanced] CH₄ + 2O₂ → CO₂ + 2H₂O

[Given] 4 mol H₂O

[Solve] x mol O₂

Step 2: Identify Conversions

[RxN] 2 mol H₂O → 2 mol O₂

Step 3: Stoichiometry

Set up conversion: $\displaystyle 4 \ mol \ H_2O(\frac{2 \ mol \ O_2}{2 \ mol \ H_2O})$ Multiply/Divide: $\displaystyle 4 \ mol \ O_2$

Answer from: chrisraptorofficial

Moles of O₂= 4

Further explanation

Given

Reaction

CH₄ + 20₂ → CO₂ + 2H₂O

4 moles of H₂O

Required

Moles of O₂

Solution

In a chemical equation, the reaction coefficient shows the mole ratio of the compounds involved in the reaction, reactants or products

From the equation, mol ratio of H₂O : O₂ = 2 : 2, so moles O₂ :

= 2/2 x moles H₂O

= 2/2 x 24

= 4 moles

Listen base your answer to the question on the information below.propane is a fuel that is sold in rigid, pressurized cylinders. most of the propane in a cylinder is liquid, with gas in the space above the liquid level. when propane is released from the cylinder, the propane leaves the cylinder as a gas. propane gas is used as a fuel by mixing it with oxygen in the air and igniting the mixture, as represented by the balanced equation below.c3h8(g) + 5o2(g) → 3co2(g) + 4h2o() + 2219.2 kja small amount of methanethiol, which has a distinct odor, is added to the propane to consumers detect a propane leak. in methanethiol, the odor is caused by the thiol functional group (–sh). methanethiol, ch3sh, has a structure that is very similar to the structure of methanol.what is the correct structural formula for a molecule of methanethiol
