aqueous potassium chloride will react with which of the following? aqueous potassium chloride will react with which of the follo
1 answer:
Answer:
potassium chloride reacts with lead nitrate.
Explanation:
According to solubility rule-
(1) All salts containing nitrate ions () are soluble.
(2) All salts containing halide ions () are soluble except halides of
.
Hence aqueous solution of potassium chloride () reacts with lead nitrate (
) to produce insoluble precipitate of lead chloride (
)
Balanced reaction:
So potassium chloride reacts with lead nitrate.

Answer:
20 molecules of oxygen gas remains after the reaction.
Explanation:
Molecules of ethyne = 52
Molecules of oxygen gas = 150
According to reaction, 2 molecules of ethyne reacts with 5 molecules of oxygen gas.
Then 52 molecules of ethyne will react with:
of oxygen gas.
As we can see that we have 150 molecules of oxygen gas, but 52 molecules of ethyne will react with 130 molecules of oxygen gas. So, this means that ethyne is a limiting reagent and oxygen gas is an excessive reagent.
Remaining molecules of recessive reagent = 150 - 130 = 20
20 molecules of oxygen gas remains after the reaction.
