A 134.0 g sample of an unknown metal is heated to 91.0°C and then placed in 125 mL of water at 25.0°C. The final temperature of the water is measured at 31.0°C. Calculate the specific heat capacity of the unknown metal.

The equation below shows the reaction of zinc with hydrochloric acid (hcl). zn (s) + 2 hcl (aq) —> zncl2 (aq) + h2 (g) what will happen if the concentration of hcl is decreased? a. more zncl2 will be produced. b. the reaction rate will slow down. c. the hydrochloric acid will become more acidic. d. the reaction will produce water instead of hydrogen gas.
