A 160.0 g-sample of metal at 89.0 degrees celsius is added to 160.0 g of H2O (l) at 13.0 degrees celsius in an insulated container. The temperature risese to 19.1 degrees celsius. Neglecting the heat capacity of the container, what is the specific heat of metal? The specific heat of H2O (l) is 4.18 J/(g*C)
A saturated solution of PbCl2 is found to contain 2.88*10^-2 M chloride ions. What is the correct value of the solubility product
Some MF2 is dissolved in water at 25oC to make a saturated solution. (M is a mystery metal - it's identity can be ignored.) Some of the solution is removed and tested
