0 0 3. A system containing 2.50 mol of an ideal gas for which Cy. m = 20.65Jmol-'K-'is taken
through the cycle in the following diagram in the direction indicated by the arrows. The
curved path corresponds to PV=nRT, where T=T1=T3.
Calculate q, w, AU, AH and for each segment and for the cycle assuming that the heat
capacity is independent of temperature.

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?
