Homework Answers
No, As long as we know the mass of A and B as well as the molecular weight of A and B. We can find out the moles of A and B, irrespective of the state they are in.
Furthermore, if we know the stiochiometirc relationship between moles of A and moles of B we can simply convert from moles of A to moles of B irrespective of the state they are in. Moles of a substance do not change when going from one state to another.

Balanced chemical equations, which represent reactions, include coefficients that describe the ratio between the reactants and products. A balanced chemical equation not only describes how many molecules or moles react with each other, but it also embodies the fact that matter and mass are conserved in a reaction. This means that all of the atoms present among the reactants will be present in the same amount among the products. For example, the combustion reaction between methane and oxygen can be...

1) Write the balanced chemical equation for the combustion of hexane, including physical states. Combustion reactions occur during burning, releasing heat and generally accompanied by light. Because of the heat, water will be produced as a vapor. 2 C 6 H 14 (g) + 19 O2(g) → 12 CO 2 (g) + 14 H2O(g) Use the balanced chemical equation above and stoichiometry to solve the following problems. 2) Calculate the maximum number of moles of carbon dioxide that...
