Methylhydrazine (CH6N2) is commonly used as a liquid rocket fuel. The combustion reaction is below. When 4.00 g of methylhydrazine is combusted in a calorimeter, the temperature increases from 25.00 oC to 39.50 o C. The calorimeter constant is 7.794 J/oC and the specific heat of methylhydrazine is 2.93 J/g oC. What is the overall heat of the reaction (kJ/mol methylhydrazine)

Cryolite, na3alf6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. start this question by first balance the chemical equation.1.) balance the equation: - alo3(s)+naoh(l)+hf(> na3alf6+h2o(g). 2.) if 17.5 kilograms of al2o3(s), 51.4 kilograms of naoh(l), and 51.4 kilograms of hf(g) react completely, how many kilograms of cryolite will be produced? 3.)which reactants will be in excess, (al2o3, naoh, or hf) 4.)what is the total mass of the excess reactants left over after the reaction is complete in kg?
