YOUR ANSWER : ?
In the reaction, Ca + 2H₂O = Ca(OH)₂ + H₂ ; what volume (c.c.) of hydrogen at STP would be liberated, when 8 gm of calcium reacts with excess water? (atomic weight of calcium = 40)
YOUR ANSWER : ?
A vessel of volume 1000 m³ contains air which is saturated with water vapour. The total pressure and temperature are 100 kPa and 20°C respectively. Assuming that the vapour pressure of water at 20°C is 2.34 kPa, the amount of water vapour (in kg) in the vessel is approximately
YOUR ANSWER : ?
What fraction of the total pressure is exerted by oxygen, if equal weights of oxygen and methane are mixed in an empty vessel at 25°C?
YOUR ANSWER : ?
A car tyre of volume 0.057 m³ is inflated to 300 kPa at 300 K. After the car is driven for 10 hours, the pressure in the tyre increases to 330 kPa. Assume air is an ideal gas and Cv for air is 21 J/mole.K. The change in the internal energy of air in the tyre in J/mole is
