A student wants to make 125 mL of a 0.050 M beryllium chloride solution. a) Calculate the number of grams of beryllium chloride necessary to make the solution.

b) Describe, in detail, how would you make this solution using the appropriate equipment.

c) After the student made the solution, he mixes it with a 2.5 M Pb(NO3)2 solution. Write the net ionic equation for this reaction.

Water is initially present in a state where its molecules are far apart. during a change of state, its molecules slow down. which change of state has most likely taken place? from a gas to a liquid from a liquid to a gas from a solid to a liquid from a gas to a plasma

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?
