The volume of 1 mole water at NTP condition will be 22.4 Litres. State whether the statement is true or false?
False. the condition that volume of 1 mole equals 22.4 Litres is valid only for GASEOUS substances. Water at NTP conditions will not be a gas. The density of water at NTP is 1 g/ml. Therefore, the volume of 1 mole water will be equal to 18 ml. (since 1 mole of water contains 18 gram of water)
Does the condition of equilibrium means that the quantity of reactants will be equal to the quantity of products?
NO! the condition of equilibrium simply means that the rate of forward reaction will be equal to the rate of backward reaction. There is no relation of the condition of equilibrium with the quantity of either reactants or products.
Do you 'always' feel weightless when an elevator is moving downwards?
NO. Feeling weightless or 'weighted' depends on the direction of acceleration and not on the direction of velocity. If acceleration of the elevator is in downward direction, then the person will feel somewhat weightlessness. (which also depends on the value of the acceleration of the elevator)
needs and Rohn will reply soon.
