250 mL of soda water (assume density of 1.00 g/mL) at 2.30°C was poured into a glass, initially at 24.0°C. The final temperature of the glass and the soda stabilized at 11.8°C. Determine the heat capacity of the glass in J/°C.

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.
