Answer:
Iron shavings
Explanation:
A substance that has a fixed chemical composition throughout and a mixture is when two or more substances are combined, but they are not combined chemically.
AlCl3(aq) is an ionic compound which will have the releasing of 3 Cl⁻ ions ions in water for every molecule of AlCl3 that dissolves.
AlCl3(s) --> Al+(aq) + 3 Cl⁻(aq)
[Cl⁻] = 0.54 mol AlCl3/1L × 3 mol Cl⁻ / 1 mol AlCl3 = 1.6 M
The answer to this question is [Cl⁻] = 1.6 M
Answer is
C. 2.07 M
For explanation
M1V1 = M2V2
M2 = (M1V1)/V2
M2 = (1.5M x 345ml) / 250 ml
:. M2 = 2.07 M
