PLZ DEAR GOD HELP XD! The equation below shows that one mole of aluminum bromide dissociates completely into one mole of aluminum ions and three moles of the bromide ions. If a solution of aluminum bromide contains 0.65 moles of aluminum ions, and the volume of the solution is 350 mL, what is the molarity of the bromide ions?

Evaluate this exponential expression,8. (2 + 3)2 – 42

In the cathode ray tube experiment, j. j. thomson passed an electric current through different gases inside a cathode ray tube in the presence of an electric field. in which two ways did this experiment change scientists’ understanding of the atom?

Plzz a sample of table sugar (sucrose, c12h22o11) has a mass of 7.801 g. ● a) calculate the number of moles of c12h22o11 in the sample b) calculate the number of moles of each element in c12h22o11 (number of moles of c, number of moles of h & number of moles of o) in the sample. (use your answer from part a as your starting point.) show your work and highlight your final answer. calculate the number of atoms of each element in c12h22o11 (number of atoms of c, number of atoms of h & number of atoms of o) in the sample. (use your answers from part b as your starting for each element.) show your work and highlight your final answer.
