The reaction for "activation" of a fatty acid ( atp + coa + rcoo- ⇋ rco-coa + amp + ppi has a δg°’ = 4.6 kj/mol. although this reaction is non-spontaneous, it is an essential reaction and thus it does occur within our bodies. the thermodynamic driving force for this reaction is the exergonic hydrolysis of ppi by the enzyme pyrophosphatase. which of the following is not a reason why the hydrolysis of ppi is exergonic?

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?
