Explanation:
Answer:
D) hydrochloric acid.
Explanation:
- The balanced equation for the mentioned reaction is:
<em>Zn(s) + 2HCl(aq) → ZnCl₂(aq) + H₂(g),</em>
<em></em>
It is clear that 1.0 moles of Zn react with 2.0 moles of HCl to produce 1.0 moles of ZnCl₂ and 1.0 mole of H₂.
- From stichiometry; Zn reacts with HCl with (1: 2) molar ratio.
<em>∴ 2.0 mol of Zn (the remaining 2.0 mol is in excess) react completely with 4.0 mol of HCl with (1: 2) molar ratio.</em>
<em />
So,
the limiting reactant is HCl and the excess reactant is Zn.
<em>Thus, the right choice is: D) hydrochloric acid.</em>
Answer:
The answer is
<h2>22 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of liquid = 44 g
volume = 2 mL
The density of the liquid is
We have the final answer as
<h3>22 g/mL</h3>
