A student pours exactly 478 mL of hydrochloric acid of an unknown molarity into a beaker and titrates the acid to neutrality using 354 mL of 1.00 M calcium hydroxide base. What is the concentration (M) of the acid?

Which of these describes the rate of this chemical reaction? h2 + cl2 → 2 hcl a. an increase in the concentration of hcl and h2 with time b. an increase in the concentration of hcl with time c. an increase in h2 and cl2 with time d. a decrease in hcl and cl2 with time
