Asingle electron has a charge of 4.5×10−15 z . using zeets and a fictitious unit of mass called the wiggle, w, the charge-to-mass ratio of an electron is 5.4×106 z/w . what is the mass of an electron in wiggles?

Determine the number o moles of ions/atoms/particle in the following: 2.50 miles of k2s (let me know how to do)

What problem would a person have if the nucleic acid in one of his or her cells were damaged?

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?
