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?

Two metal blocks that have slightly different temperatures are placed next to one another. after five minutes, they both have lower but equal temperatures. according to the law of conservation of energy, what  most likelyhappened? energy was created inside the blocks.energy was destroyed inside the blocks.energy was absorbed into the blocks from outside the system.energy was transferred from the warmer block to the cooler block.
