Consider the reaction that converts pyruvic acid (CH3COCOOH) into gaseous acetaldehyde ( CH3CHO ) and gaseous CO2 , which is catalyzed in aqueous solution by the enzyme pyruvate decarboxylase. Assume ideal gas behavior for CO2 . 98 Chapter 3 | The Second Law: The Entropy of the Universe Increases a. Calculate !rG"(298 K) for this reaction. b. Calculate !rG(298 K) for this reaction at 100 bar. State any important assumptions needed in addition to ideal

Can someone me with 1 to 4 plz. fast

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?
