Use this equation: N2 + 3 H2 ---> 2 NH3, for the following problems  a) If you used 1 mole of N2, how many moles of NH3 could be produced?   b) If 10 moles of NH3 were produced, how many moles of N2 would be required?  c) If 3.00 moles of H2 were used, how many moles of NH3 would be made?  d) If 0.600 moles of NH3 were produced, how many moles of H2 are required?

Water (2510 g ) is heated until it just begins to boil. if the water absorbs 5.09×105 j of heat in the process, what was the initial temperature of the water?

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?
