Hiii,so the problem is ♀️
Answer;
= 0.054 kg or 54 g
Explanation;
Using the equation; Q = mcΔT where Q is the quantity of heat transferred, m is the mass, c is specific heat of the substance, ΔT is delta T, the change in temperature.
ΔT = 75 - 20 = 55 C.
Solve the equation for m
m = Q/ cΔT
Mass = 12500 / (55 × 4200)
= 0.054 kg or 54 g
It cools down i am 100 percent sure it cools down
I think this is it
Cd(HCO3)2---->CdCO3+H2O+CO2
Sorry if this is wrong
