This is what I was given: Answer all of the questions concerning the combustion of table sugar, [tex]C_1_2H_2_2O_1_1(s) + 12O_2 (g)\rightarrow 11H_2O(g) + 12CO_2(g)[/tex] a. If (weird triangle shape thing(what is this thing anyways?))H for this reaction is -5645 kj/mol, how much heat is produced when 2 mol of sugar are burned? b. How much heat is produced when only 3 mol of [tex]O_2[/tex] are available c. Could this combustion reaction ever have a positive (weird triangle shape)H? Explain. I am completely stuck, I have no idea even where to start on this problem, and its due tomorrow. A million thanks to anyone who can help me!!!
