Jake collected samples of two substances while he was out walking. After taking the samples home, he ran tests and found that on
2 answers:
Answer: One substance which is slippery and conducts electricity in water is probably a base. The other substance which continuously made bubbles of hydrogen gas when Jake dropped magnesium into an aqueous solution of the substance is probably a acid.
Explanation: Bases are those substances which donates ions when dissolved in water. Thus bases produce ions which help in the conduction of electric current.
Bases are slippery in nature and are used in manufacturing of soaps.
Acids are those substances which donates ions when dissolved in water. Thus acids also produce ions which help in the conduction of electric current. Acids are not slippery in nature.
Thus magnesium when dropped into an aqueous solution of the acid releases hydrogen gas.

<u>Answer:</u> 6 moles of will be decomposed.
<u>Explanation:</u>
We are given:
Moles of oxygen gas produced = 9 moles
The chemical equation for the decomposition of follows:
By the stoichiometry of the reaction:
If 3 moles of oxygen gas is produced by 2 moles of
So, 9 moles of oxygen gas will be produced by = of
Hence, 6 moles of will be decomposed.
