Question

1) Name the following covalent compounds (using the naming rules from the text and lecture) (5 points).

N2H4 _____
HBr(aq) ______
N2O _______
C6H6 (l) _______

2) Write the chemical formula. and indicate net charge where relevant compounds, (> points)

Sulfur hexachloride ________
Sulfate _________
Disilicon tetrafluoride ______
Carbonate ________

Answer 1

Carbonate is right the others do not applaud to its potential

Answer 2

Dinitrogen Tetrahydrogen

Hydrogen Monobromide

Dinitrogen Monoxide

Hexacarbon Hexahydrogen

2)Sulfur Hexachloride.SCl6(six should be a subscript) Netcharge = -8.

Sulfate = SO4(4 is subscript) Netcharge = -2

Disilicon Tetrafluoride = S2F4(2 and 4 should be subscript numbers. Net charge = -4.

Carbonate = CO3(3 is subscript). Netcharge= -2.

Step-by-step explanation:

Prefixes for covalent compounds are.

1 - mono

2 - di

3 - tri

4 - tetra

5 - penta

6 - hexa

7 - hepta

8 - octa

9 - nona

10 - deca

Sulfur has a charge of -2. Chlorine has a charge of -1. Hexachloride implies 6 chlorine. 6x -1 = -6. Sulfur is -2. -6+-2=-8.

Sulfate is on a common ion sheet.

Disilicon Tetrafluoride is S2F4= S has a charge of -2. -2x2=-4. F has a charge of -1. -1 x 4=-4 -4+-4=-8.

Carbonate is on a common ion sheet.
