Methane (CH4) is the main component of natural gas. It is burned for fuel in a combustion reaction. The unbalanced combustion reaction for methane is shown below.CH4 + O2 CO2 + H2O + heatWhen the reaction is balanced, how many carbon dioxide molecules are produced for every methane molecule burned?A.3B.2C.4D.1

Air contains 79% N2 and 21% O2 on a molar basis. Methane (CH4) is burned with 50% excess air than required stoichiometrically. Assuming complete combustion of methane, the molar percentage of N2 in the products is::

Combustion of hydrocarbons such as methane (CH4) produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the Earth's atmosphere can trap the Sun's heat, raising the average temperature of the Earth. For this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.1. Write a balanced chemical equation, including physical state symbols, for the combustion of gaseous methane into gaseous carbon dioxide and gaseous water.2. Suppose 0.350kg of methane are burned in air at a pressure of exactly 1atm and a temperature of 12.0°C. Calculate the volume of carbon dioxide gas that is produced. Be sure your answer has the correct number of significant digits.L

If methane is burnt in sufficient oxygen the products formed are :A.

KA1 Complete the sentence below.The subscripted number 4 in the chemical formula for methane (CH4) tells us that there are:4 molecules of CH4 atoms of hydrogen in a methane molecule4 atoms of carbon in a methane molecule4 atoms of methane

The image shows the combustion of methane. Which equation represents this chemical reaction? A. CH4 + O2 → CO2 + H2O B. 2CH4 + 2O2 → CO2 + 2H2O C. CH4 + 2O2 → 2CO2 + H2O D. CH4 + O2 → 2CO2 + 2 H2O E. CH4 + 2O2 → CO2 + 2H2O
