select the correct answer from each drop - down menu. identify each substance based on its description. jake collected samples of two substances while he was out walking. after taking the samples home, he ran tests and found that one substance is slippery and conducts electricity in water. these properties made jake conclude that the substance is probably. the other substance continuously made bubbles of hydrogen gas when jake dropped magnesium into an aqueous solution of the substance. jake concluded that the second substance is probably. reset next
Answer
Explanation:
Step1: Analyze first - substance properties
Slippery and conducts electricity in water are properties of bases. Bases dissociate in water to form ions which can conduct electricity, and they feel slippery to the touch.
Step2: Analyze second - substance reaction
When magnesium reacts with an acid in an aqueous solution, it produces hydrogen gas. The reaction is $Mg + 2H^+ \rightarrow Mg^{2+}+H_2\uparrow$. So the substance that produces hydrogen gas when magnesium is dropped into its aqueous solution is an acid.
