USING LEWIS ELECTRON DOTSG
CROSS.(2)B) WHY DO SUCH
COMPOUNDS CONDUCTS
ELECTRICITY ONLY IN THEIR
AQUEOUS OF FUSED STATE.
(1)C)WHAT WILL BE THE FORMULA
OF THE COMPOUND WHEN P
REACTS WITH OXYGEN (1)D) NAME
THE COMPOUND FORMED WHEN P
DISSOLVES IN WATER. WHAT WILL BE
THE PH RANGE OF THE COMPOUND
FORMED BY P & WATER?(1)​

Answer 1

A.)....op2

p.*o*.p

where... * is cross and . is dot

B) such compounds conduct electricity in fused aqueous state because the electrons that are able to conduct electricity become free to move in aqueous solution than that of the solid state. Also, their velocity increases after the solution become fused.

1)C) PO 1)D) P(OH)2 +H2
