Question

this passage describes a chemical reaction. read the passage. then, answer the question below. some chemical factories use the chloralkali process to make substances from brine, which is a mixture of sodium chloride (nacl) and water (h₂o). in this process, factory workers send currents of electricity through the mixture, causing sodium hydroxide (naoh), chlorine gas (cl₂), and hydrogen gas (h₂) to form. these substances can later be used to create other chemicals like bleach and drain cleaner. in the chemical reaction described in the passage, which of the following are products? select all that apply. sodium chloride (nacl) sodium hydroxide (naoh) hydrogen (h₂) chlorine (cl₂)

Explanation:

In a chemical reaction, reactants are the starting substances, and products are the substances formed. The passage says brine (a mixture of NaCl and H₂O) is used, and electricity through it causes NaOH, Cl₂, and H₂ to form. So NaCl is a reactant (part of brine), while NaOH, H₂, and Cl₂ are products.

Answer:

B. sodium hydroxide (NaOH)
C. hydrogen (H₂)
D. chlorine (Cl₂)
