Answer: When an iron nail immersed in the solution of copper sulphate than iron displaces copper from the solution of copper sulphate because iron is more reactive than copper. Therefore copper sulphate solution colour changes from blue to pale green.
Answer: 500000 centimeters
Explanation:
Answer:
0.89 atm is the pressure of the hydrogen gas
Explanation:
We can use the molar fractions to solve this
Sum of molar fractions (hydrogen + water vapor) = 1
Molar fraction = Pressure gas / Total pressure
Molar fraction water vapor = 0.13 atm/1.02 atm = 0.127
1 - 0.127 = 0.873 (Molar fraction H2)
0.873 = Pressure H2 / Total pressure
0.873 = Pressure H2 / 1.02 atm
0.873 . 1.02atm = 0.89 atm
