Combustion of Methane Concepts

The video tutorial explains how to predict the products of a reaction between methane and oxygen gas. It classifies the reaction as a combustion reaction, resulting in carbon dioxide and water as products. The tutorial also covers balancing the chemical equation for this reaction, emphasizing the exothermic nature of combustion reactions. The process involves recognizing the presence of carbon, hydrogen, and oxygen, which consistently yield CO2 and H2O.

What is the first step in predicting the products of a chemical reaction?

• Classify the type of reaction

• Determine the pressure

• Measure the temperature

• Identify the reactants

What type of reaction occurs when methane reacts with oxygen gas?

• Synthesis

• Decomposition

• Combustion

• Single replacement

Which of the following is a product of the combustion of methane?

• CH4

• O2

• CO2

• N2

Why is water likely to be in a gaseous state during the combustion of methane?

• Because it is endothermic

• Because it is exothermic

• Because it is a solid

• Because it is a liquid

What is the balanced chemical equation for the combustion of methane?

• CH4 + O2 → CO2 + H2O

• CH4 + 2O2 → CO2 + 2H2O

• 2CH4 + O2 → 2CO2 + H2O

• CH4 + O2 → 2CO2 + 2H2O

What is the role of oxygen in the combustion of methane?

• It is an inhibitor

• It is a reactant

• It is a product

• It acts as a catalyst

What consistent products are formed when carbon and hydrogen react with oxygen?

• CO and H2

• C2H6 and H2O

• CH4 and O2

• CO2 and H2O
