If you start with 163 g of water at 29◦C, how much heat must you add to convert all the liquid into vapor at 100◦C? Assume no heat is lost to the surroundings. Answer in units of kJ.

A typical ice cube has a volume of about 16.0 cm3. Calculate the amount of energy needed to melt the ice cube. (Density of ice at 0.°C = 0.917 g/mL; molar enthalpy of fusion of ice = 6.009 kJ/mol; molar mass of H2O = 18.02 g/mol.)

A chemist determined by measurements that 0.050 moles of aluminum participated in a chemical reaction. Calculate the mass of aluminum that participated in the chemical reaction. Be sure your answer has the correct number of significant digits.

In 1901, Thomas Edison invented the nickel-iron battery. The following reaction takes place in the battery. Fe (s) + 2 NiO (OH) (s) + 2 H2O (l) Fe (OH) 2 (s) + 2 Ni (OH) 2 (aq) How many mole of Fe (OH) 2, is produced when 5.35 mol Fe and 7.

As you move from left to right across the periodic table, the atomic numbers increase decrease stay the same are random

Use the octet rule to predict the formula of the compound that would form between fluorine and iodine, if the molecule contains only one fluorine atom and only single bonds are formed.

64.0 grams of Sulfur Dioxide absorbed 5.00 kJ of heat and immediately evaporated. With this information, calculate its molar enthalpy of vaporization in units kJ/mol.
