docker41 [41]

3.2 g KClO3

Explanation:

1.1 g C12H22O11 × (1 mol C12H22O11/342.3 g C12H22O11)

= 0.0032 mol C12H22O11

0.0032 mol C12H22O11 × (8 mol KClO3/1 mol C12H22O11)

= 0.026 mol KClO3

Therefore, the minimum amount of KClO3 needed is

0.026 mol KClO3 × (122.55 g KClO3/1 mol KClO3)

= 3.2 g KClO3

Choose the statement below that is TRUE. Question 7 options: The term "strong electrolyte" means that the substance is extremely
Setler [38]

Answer: A weak acid solution consists of mostly nonionized acid molecules.

Explanation:

Strong electrolytes are those solutions which undergo complete dissociation when dissolved in water. The dissociation of strong electrolytes is given by a right arrow.

Weak electrolytes are those solutions which do not undergo complete dissociation when dissolved in water. The dissociation of weak electrolytes is given by a rightleft arrow.

Weak acids are those substances which dissociate partially to give H^+ ions when dissolved in water. Thus most of molecules remain unionized in solutions.

CH_3COOH\rightleftharpoons CH_3COO^-+H^+

Strong acids are those substances which dissociate completely to give H^+ ions when dissolved in water.

HNO_3(aq.)\rightarrow H^+(aq.)+NO_3^-(aq.)
