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
Answer:
1. open
2. open
Explanation:
1. An open system can exchange energy and matter.
2. The ocean is known to be an open system.
Answer: This means to find the number of neutrons you subtract the number of protons from the mass number.
P = nRT/V
P = 3.5 x 10^-3 x 0.082 x 298 /0.5
P = 0.171 m Hg
P = 171 mm Hg
hope this helps
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
ions when dissolved in water. Thus most of molecules remain unionized in solutions.

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