Answer:
The rate of flow of nitrogen into the reactor is 2,470.588 kg/h.
Explanation:
Mole percentage of nitrogen gas = 25 mole%
Mole percentage of hydrogen gas = 75 mole%
Average molecular weight of the mixture:
Rate of flow of the stream = 3000 kg/h
Mass of stream in 1 hour = 3000 kg = 3,000,000 g
Moles of stream :
Moles of nitrogen gas in 352,941.17 moles of stream be x
x = 88,235.294 mol
Mass of 8,823,529.4 mole of nitrogen gas:
The rate of flow of nitrogen into the reactor is 2,470.588 kg/h.
Answer:
The gold gains a total of 2.468 kilo-joules of energy.
Explanation:
Total heat or energy gained by the gold is equal to heat applied and heat required to melt the gold completely.
Total energy = Q+ Q'
Heat of fusion of gold =
Mass of gold melted ,m= 12.5 g
Specific heat of gold ,c= 0.1291 joules/gram °C
Change in temperature = ΔT = 1064°C - 26°C = 1038 °C
Heat of applied to the gold = Q
Total energy = Q+ Q'
= 2,468.82 Joule= 2.468 kilo-Joule
The gold gains a total of 2.468 kilo-joules of energy.
