Using the bond energies below, calculate an estimate of ahrxn for the gas phase reaction: qx3 + 3h20 => q(oh)3 + 3hx do not enter units with your answer. bond be (kj/mol) q-x 240 o-h 464 q-o 359 h-x 449

Concerning the 10.0 ml of 0.50 m nacl to 100 ml of solution: when a solution is diluted, does it change the number of moles dissolved?

If two atoms are bonded to a central atom with no lone pairs,how will they be arranged

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?
