A 42.1 g piece of metal was heated up to 97.4 oC and then dropped into a beaker containing 63.0 g of water at 22.0 oC. When the water and metal come to thermal equilibrium, the temperature is 30.10 oC. What is the specific heat capacity of the metal? Specific heat capacity of the water is 4.184 J/(g• oC)

Use the Lewis dot structure (make sure you show all electron pairs) and VSEPR theory to predict which of the following molecules is polar.

A 25.00 mL sample of the sulfuric acid solution was titrated with 45.42 mL of a 0.9598 M solution of sodium hydroxide, NaOH. Use the equation below to find the stoichiometric (mole) ratio and apply it to calculate the molar concentration of the sulfuric acid, H2SO4. H2SO4(aq) + 2 NaOH(aq)   →  Na2SO4(aq) + 2 H2O(l)
