Answer:
It is A.
Explanation:
I hope this helps have a great day.
The classification of whipped cream is a foam.
So, option C is correct one.
The whipped cream is a colloid and it consists of gas ( dispersed phase ) in liquid ( dispersed medium) system.
Sol is a solid dispersed in the liquid . Examples includes Au , S sol in water , milk of magnesia .
The emulsion is liquid dispersed into the liquid . Example is milk
Foam is a gas dispersed into the liquid . Examples includes whipped cream , shaving cream , foam on the beer .
Gel is the liquid dispersed into the solid . Examples includes , butter , jellies .

Answer:
184.113 g/mol
Explanation: The atomic mass of Mg is 24.3 amu. The atomic mass of bromine is 79.9. Therefore, the formula weight of MgBr2 equals 24.3 amu + (2 × 79.9 amu), or 184.1 amu. Because a substance's molar mass has the same numerical value as its formula weight, the molar mass of MgBr2 equals 184.1 g/mol.
Answer:
2.2×10^8
Explanation:
Cu(OH)2(s)<---------> Cu^2+(aq) + 2OH^-(aq) Ksp=2.2 x 10 ^-20
2H3O^+(aq) + 2OH^-(aq) <-------> 4H2O(l). Kw= 1×10^14
Cu^2+(aq) + 4H2O(l) <--------> [Cu(H2O)4]^2+(aq)
Overall ionic reaction:
Cu(OH)2(s) +2H3O^+(aq) <---------> [Cu(H20)4]^2+(aq)
Equilibrium constant for the reaction: Ksp×Kw= 2.2 x 10 ^-20 × (1/(1×10^-14))^2
Keq= 2.2×10^8
Kw= ion dissociation constant of water
