- In case of a solution (not of a solid in a liquid), whose total volume is less than the sum of the volumes of its components in their pure states, solubility is
- In case of a solution (not of a solid in a liquid), whose total volume is more than the sum of volumes of its components in their pure states, solubility is
- What is the simplest formula of a compound containing 50% of element A (atomic weight = 10) and 50% of element B (atomic weight = 20)?
- Under conditions of equal reduced pressure and equal reduced temperature, substances are said to be in the 'corresponding states'. At equal reduced conditions i.e., at the corresponding state, the __________ of different gases are nearly the same.
- If pH value of an acidic solution is decreased from 5 to 2, then the increase in its hydrogen ion concentration is __________ times.
- The heat capacity of a solid compound is approximately equal to the sum of the heat capacities of the constituent elements. This is the statement of
- In the reaction, represented by Na₂CO₃ + HC₁ → NaHO₃ + NaCl, the equivalent weight of Na₂CO₃ is
- One kg of saturated steam at 100°C and 1.01325 bar is contained in a rigid walled vessel. It lias a volume of 1.673 m³. It cools to 98°C ; the saturation pressure is 0.943 bar ; one kg of water vapour under these conditions has a volume of 1.789 m³. The amount of water vapour condensed (in kg) is
