Two identical blocks are heated to different temperatures. The blocks are placed so that the touch, and heat begins to flow between the blocks. The pair of blocks is insulated, so no
energy escapes.

10-14. (a) when 100.0 ml of weak acid ha were titrated with 0.093 81 m naoh, 27.63 ml were required to reach the equivalence point. find the molarity of ha. (b) what is the formal concentration of a- at the equivalence point? (c) the ph at the equivalence point was 10.99. find pk. for ha. (d) what was the ph when only 19.47 ml of naoh had been added?

Covalent network solids typically have melting points and boiling points. the chemical formula of a network solid indicates in the molecule.
