In a typical chemical reaction the subscript for a particular atom is written

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?

Frictional forces acting on an object are often converted into energy, which causes the temperature of the object to rise slightly.

If a solution had a ph of 7 what is the solution
