Choose the correct net ionic reaction for HNO,+NaOH Tonic Equatons r-or-Ho None of the above e. b. +4

Explanation / Answer

1.

(d) Because it is a polar molecule and able to form intermolecular hydrogen bonds.

2.

(b) Because it is a non polar molecule.

3.

M1V1 = M2V2

M1 * 21.34 = 0.116 * 20.78

M1 = 0.113 M

(b)

4.

M1V1 = M2V2

0.125 * V1 = 0.333 * 10.00

V1 = 26.64 mL

5.

(c) Effusion is process ogmoment of gas molecules through a small hole

6.

(d) Because both HNO3 and NaOH are strong electrolytes and undergo complete ionisation.

7.

CaHPO4

+2 +1 + x + 4 ( - 2 ) = 0

+ 3 + x - 8 = 0

x - 5 = 0

x = + 5

(c)
