Question

this passage describes a chemical reaction. read the passage. then, follow the instructions below. many power plants produce electricity using natural gas, a fuel composed mostly of methane (ch₄). these power plants burn methane at high temperatures and pressures, causing it to combine with oxygen (o₂) in the air. this creates a mixture of hot gases that includes carbon dioxide gas (co₂) and water vapor (h₂o). the energy in this mixture of gases is used to make electricity. complete the table to classify the substances in this chemical reaction. substances: carbon dioxide (co₂), methane (ch₄), oxygen (o₂), water (h₂o), reactant, product

Explanation:

Step1: Identify reactants

Reactants are substances that participate in a chemical - reaction and are consumed. From the passage, methane ($CH_4$) and oxygen ($O_2$) are used up in the reaction, so they are reactants.

Step2: Identify products

Products are substances that are formed as a result of a chemical reaction. Carbon dioxide ($CO_2$) and water ($H_2O$) are formed in the reaction, so they are products.

Answer:

Substance	Reactant	Product
Methane ($CH_4$)	X
Oxygen ($O_2$)	X
Water ($H_2O$)		X
