How many moles of CCI are there in 78.2 g of CCI.? 0.508 moles
12.028 moles
1.55 x 10-4moles
153.8 moles

Why are the trends and exceptions to the trends in ionization energy observed?

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?

Me soon im confused much mass would a mole of hydrogen molecules contain? recall that hydrogen is diatomic. g/mol
