A result of the common ion effect is that the selective precipitation of a metal ion, such as Ag+, is promoted by the addition of an appropriate counter ion (X-) that produces a compound (AgX) with a very low solubility.
Answer:
The answer to your question is: Q = 3153600 Joules
Explanation:
Data
Q = ?
m = 48 kg
T1 = 21°C
T2 = 94°C
Cp = 900 J/g°C
Formula
Q = mCpΔT
Q = (48)(900)(94 - 21) = 3153600 Joules
Answer:
The dissociation equations for NaBr gives Na+ and Br-
The dissociation equations for ZnCl2 gives Zn2+ and 2 Cl-
Explanation:
The following pictures shows that the dissociation of one particle of NaBr produces one particle of Na+ (sodium cation) and one particle of Br- (bromine anion).
The dissociation of one particle of ZnCl2 produces one particle of Zn+2 (Zinc cation) and two particles of Cl- (chlorine anion).
