Question

this passage describes a chemical reaction. read the passage. then, answer the question below. many chemical factories use the haber process to make ammonia (nh₃). in this process, nitrogen gas (n₂) and hydrogen gas (h₂) combine at high temperatures and pressures. ammonia from the haber process can be used as fertilizer for plants. fertilizers are made of compounds containing chemical elements such as nitrogen that help plants grow. in the chemical reaction described in the passage, which of the following are reactants? select all that apply. nitrogen (n₂) hydrogen (h₂) ammonia (nh₃)

Explanation:

To determine reactants, we recall that in a chemical reaction, reactants are the substances that combine to form products. The passage states: "nitrogen gas (N₂) and hydrogen gas (H₂) combine... to make ammonia (NH₃)". So N₂ and H₂ are reactants (they react), while NH₃ is the product (what is made). The original selection incorrectly marked NH₃ as a reactant; it should be unselected.

Answer:

The correct reactants are:

• nitrogen (N₂)
• hydrogen (H₂)

(Note: Ammonia (NH₃) is a product, not a reactant, so it should not be selected.)
