Suppose a 1.25 g sample of CaCO$_3$ is decomposed by heating. How many milliliters of CO$_2$ gas will be evolved if it will be measured at 0.974 atm and 25 $^{\circ}$C (MM of CaCO$_3$ = 100.05 g/mol)

CaCO$_3$ (s) $\longrightarrow$ CO$_2$ (g) + CaO (s)

A 25.0 g piece of metal is heated to 200.0$^\circ$ C and placed in 30.0 g of 25.0$^\circ$ C water. The temperature of the water rises to 41.0$^\circ$ C. What is the specific heat of the metal?
