If 114 grams of CS2 are burned in an excess of O2 (an amount sufficient to burn completely all 114 g of CS2), how many moles of SO2 are formed?
What conceptual error did he make? Determine the correct empirical formula for this compound.
The initial rate of a reaction 2A + 3B -> C + 2D was measured using different initial concentrations of A and B. Use the information in the table to determine the rate law for the reaction.
Calculate the integral of dqrev / T for each of the 4 steps in the Carnot cycle of, and sum them to prove that their sum equals zero. This turns out to also be true for any cyclic process that returns the system
