Answer:
56.6g
Explanation:
Given that :
Mass of water, m1= 300.0 g
Temperature of water, T1= 22°C
Specific heat capacity of water, C= 4.184 J/g°C
Mass of polystyrene, m2=?
Temperature of polystyrene = 94.9
Specific heat capacity of polystyrene, c2= 1.88 J/g°C
Final temperature = 27.7 oC
Heat lost by polystyrene = Heat gained by water
mc(dT) = mc(dT)
m2 * 1.88 * (94.9 - 27.7) = 300 * 4.184 * (27.7 - 22)
m2 * 1.88*67.2 = 300*4.184*5.7
126.336 * m2 = 7154.64
m2 = 7154.64 / 126.336
m2 = 56.631838
Hence, mass of polystyrene = 56.6g
Answer:
- The metal industry uses large quantities of copper sulphate as an electrolyte in copper refining, for copper coating steel wire prior to wire drawing and in various copper plating processes
.
- The mining industry employs it as an activator in the concentration by froth flotation of lead, zinc, cobalt and gold ores
.
- The paint industry uses it in anti-fouling paints and it plays a part in the colouring of glass.
Explanation:
Hello,
In this case, since copper sulphate also known as blue stone, blue vitriol is more commonly found in a pentahydrated cupric sulphate due to its stability. In fact it is often the starting raw material for the production of other varied copper-based salts. Henceforth, you will find three applications.
