Which statement generally describes the oxides formed when non-metals burn in oxygen?
They produce acidic oxides.
Non-metals generally form acidic oxides on reacting with oxygen; such oxides can produce acids in water. Some non-metal oxides, such as CO and NO, are neutral exceptions.
Concentration of a solution can be expressed in :
1. Molarity
2. Molality

What will happen to the boiling point of water when a little common salt is added to water and then heated?
Which Statement is correct ?
The pH value of 1 × 10 -8 (M) HCl is:
Tyndall effect is not observed in:
A non-volatile solute, urea ($CO(NH_2)_2$, molar mass $60 \ g/mol$), is dissolved in $180 \ g$ of water ($H_2O$, molar mass $18 \ g/mol$). If the vapor pressure of pure water at a certain temperature is $50 \ mmHg$, what is the vapor pressure of the solution when $18 \ g$ of urea is added?
