How many moles of methane are produced when 4.53 mol co2 reacts

ArbitrLikvidat [17]

The reaction formula CH4 + 2O2 → CO2 + 2H2O shows the oxidation of 1 mole of CH4 (Methane) will yield 1 mole of CO2 (Carbon Dioxide). Since 1 mole of CH4 will weigh 12g (for the Carbon) + 4g (1g for each Hydrogen) = 16g, then 32g of CH4 will correspond to 32g / 16g/mole = 2 moles. Therefore the oxidation of 2 moles of CH4 will yield 2 moles of CO2.

What is the volume of 40.0 grams of argon gas at STP ?

MrRa [10]

Answer:

24.9 L Ar

General Formulas and Concepts:

Atomic Structure

Reading a Periodic Table
Moles
STP (Standard Conditions for Temperature and Pressure) = 22.4 L per mole at 1 atm, 273 K

Aqueous Solutions

States of Matter

Stoichiometry

Using Dimensional Analysis

Explanation:

Step 1: Define

[Given] 40.0 g Ar

[Solve] L Ar

Step 2: Identify Conversions

[PT] Molar Mass of Ar - 39.95 g/mol

[STP] 22.4 L = 1 mol

Step 3: Convert

[DA] Set up: $\displaystyle 40.0 \ g \ Ar(\frac{1 \ mol \ Ar}{39.95 \ g \ Ar})(\frac{22.4 \ L \ Ar}{1 \ mol \ Ar})$
[DA] Divide/Multiply [Cancel out units]: $\displaystyle 24.9235 \ L \ Ar$

Step 4: Check

Follow sig fig rules and round. We are given 3 sig figs.

24.9235 L Ar ≈ 24.9 L Ar

The revival of jansenism, which centered on miracles that allegedly happened at the grave of a jansenist priest, is evidence of

lapo4ka [179]

The evidence of the revival of Jansenism is the desire of ordinary people to connect themselves to what they saw as the direct work of God.

<h3>What is Jansenism?</h3>

Jansenism is a theological movement that is done with the mixing of Catholicism. It was active in France's kingdom.

Primarily throughout the seventeenth and eighteenth centuries, Jansenism flourished inside Roman Catholicism before being denounced as heresy in 1653 by Pope Innocent X.

Thus, the yearning of common people to participate in what they perceived as God's direct action is proof of the rebirth of Jansenism.
