CaCl₂ + 2 AgNO₃ = Ca(NO₃)₂ + 2AgCl
Calcium Chloride + Silver Nitrate = Calcium Nitrate + Silver Chloride

hope this helps!
Flashlight or smoke detector have simple dry cell or batteries.
The cell are generally of 6 volts.
In these cells Zn acts as anode and graphite electrode acts as cathode.
A mixture of MnO2 and carbon blacks surrounds the graphite cathode
The electrolyte is ZnCl2 and ammonium chloride. This mixture is used as thick paste.
Use Law of Graham.
rate A / rate B = √ (molar mass B / molar mass A)
rate A / rate B = 2.5
molar mass A = 32.0 g/mol
=> (molar mass B / molar mass A) = (rate A / rate B)^2
molar mass B = molar mass A * (rate A / rate B)^2
molar mass B = 32.0 g/mol * (2.5)^2 = 200. g/mol
Answer: 200 g/mol
If you were to add more solute to a solution it would be more concentrated
