The question here is solved using basic chemistry. CaCl2(aq) is an ionic compound which will have the releasing of 2 Cl⁻ ions ions in water for every molecule of CaCl2 that dissolves.
CaCl2(s) --> Ca+(aq) + 2 Cl⁻(aq)
[Cl⁻] = 0.65 mol CaCl2/1L × 2 mol Cl⁻ / 1 mol CaCl2 = 1.3 M
The answer to this question is [Cl⁻] = 1.3 M
The answer is transition metals.
The volume of the snow decreases. This had happened because the
snow is made up or comprised of water (H2O) and oxygen (O). When the snow starts
melting, the air inside the snow discharges into the atmosphere and the water turn
out to be a puddle on the ground.
