Answer:
The answer to your question is: Cp = 350.4 J/ kg°C
Explanation:
Data
mass = m = 4.7 g convert grams to kilograms 0.0047 kg
heat= Q = 52.7 J
Temperature = 25 - 57 °C
Formula
Q = mCpΔT solve for Cp
Cp = Q / mΔT
Process
Cp = 52.7 / [(0.0047)(57 - 25)] Substitution
Cp = 52.7 / 0.1504
Cp = 350.4 J/ kg°C
If its oxidised, water and carbon dioxide is formed.
Answer:
H₂: 0.48, N₂: 0.43; Ar: 0.09
Explanation:
First of all, sum all the pressures to know the total pressure in the mixture.
434 Torr + 389.9 Torr + 77.9 Torr = 901.8 Torr
Mole fraction = Pressure gas / Total Pressure
Mole Fraction H₂: 434 Torr /901.8 Torr = 0.48
Mole Fraction N₂: 389.9 /901.8 Torr =0.43
Mole Fraction Ar: 77.9 /901.8 Torr = 0.09
Remember: <u>SUM OF MOLE FRACTION = 1</u>
There are two hydrogen atoms in one molecule of water.
The answer is B) 2
