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. substance reactant product carbon dioxide (co₂) methane (ch₄) oxygen (o₂) water (h₂o)

Explanation:

Reactants are substances that undergo a chemical reaction, and products are the new substances formed. In the described reaction, methane ($\ce{CH4}$) and oxygen ($\ce{O2}$) are the starting materials (reactants) that combine. Carbon dioxide ($\ce{CO2}$) and water ($\ce{H2O}$) are the resulting substances (products) from the reaction.

Answer:

Substance	Reactant	Product
methane ($\ce{CH4}$)	✔️
oxygen ($\ce{O2}$)	✔️
water ($\ce{H2O}$)		✔️
