Cyclobutane decomposes to ethylene according to the equation c4h8(g) ⟶ 2c2h4(g) determine the order of the reaction and the rate constant based on the following pressures, which were recorded when the reaction was carried out at 430°c in a constant-volume vessel. time (s) pc4h8 (mmhg) 0 400 2,000 316 4,000 248 6,000 196 8,000 155 10,000 122

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?
