How many moles of co2 will be produced from 72.0 g of ch4 assuming o2 is available in excess
Moles of CO₂ produced will be 4.5
<u>Explanation:</u>
CH₄ + 2O₂ → CO₂ + 2H₂O
Molecular weight of CH₄, M = 16
given mass of CH₄, m = 72
moles of CH₄, n = given mass / molecular mass
Therefore, number of moles of CH₄ present is 4.5
According to the balanced equation,
1 mole of CH₄ produces 1 mole of CO₂
4.5 moles of CH₄ will produce 4.5 moles of CO₂
Therefore, moles of CO₂ produced will be 4.5

Dilution of the solution can be calculated by the formula of the molarity and volume. The initial volume of 2.50 M solution was 30 mL.
<h3>What is the relationship between molar concentration and dilution?</h3>Molar concentration or the dilution factor is in an inverse relationship and with an increase in the dilution, the molarity of the solution decreases.
Given,
Initial molarity = 2.50 M
initial volume = ?
Final molarity = 0.750 M
Final volume = 100.0 ml
Substituting values in the formula:
Therefore, 30 mL was the initial volume of the solution before it was diluted.

Explanation:
Mass = volume × density
Mass = 652 cm³ × 21.45 g/cm³
= 13985.4 g

Answer:
The answer is 159.6882.
Assuming you are converting between grams Fe2O3 and mole.
Work allows energy to be transferred from one object to another. To do work, an agent must exert a force on an object over a long distance.
When work is done, energy is transferred from the agent to the object, resulting in a change in the motion of the object (more specifically, a change in the object's kinetic energy).
What is energy?
Energy is essential to human society and has numerous health benefits. However, each energy source poses some health risks. This article examines the health consequences of each major source of energy, focusing on those with the greatest global impact on disease burden. The harvesting and burning of solid fuels, coal, and biomass have the greatest health consequences, primarily in the form of occupational health risks and household and general ambient air pollution. In the world's poorest households, a lack of access to clean fuels and electricity poses a particularly serious health risk. Although energy efficiency has many advantages, energy use is essential to human society and has numerous health benefits.
