Achemist is performing a titration in order to determine the amount of lithium hydroxide, lioh(aq), in 135 ml of an aqueous solution.

(a) if 28 ml of a 0.15 m hcl solution was used as a titrant to reach the equivalence point, what was the concentration of lithium hydroxide in the initial solution?

(b) what was the initial ph of the lithium hydroxide solution?

Plz choose one of the compounds from the table and explain how you know the numbers of atoms in your formula. is it possible for two different compounds to be made from the exact same two elements? why or why not? with a limited number of elements (less than 120 are known), does this mean we also have a small number of compounds or do we have a large number of compounds in this world?

Which compound contains both ionic and covalent bonds? a) hbr b)cbr4 c)nabr d) naoh
