Write balanced chemical equations for the complete neutralization reactions that take place when the following acids are titrated with sodium hydroxide (a) hydrochloric acid, (b) acetic acid, and (c) phosphoric acid.

(a)

(b)

(c)

Explanation:

For a reaction involving sodium hydroxide and hydrochloric acid, the balanced equation of reaction is:

For a reaction involving sodium hydroxide and acetic acid, the balanced equation of reaction is:

For a reaction involving sodium hydroxide and phosphoric acid, the balanced equation of reaction is:

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

c. 4.54 x 10–12 j happens to be correct
