42 gm of a mixture of propyne `(C_(3)H_(4))` and oxygen gas is collected in a vessel and fired. The maximum possible mass (in gm) of water formed is-

When 4 gm of a mixture of NaHCO_(3) and NaCl is heated , 0.66 gm CO_(2) gas is evolved . Determine the percentage composition (by mass) of the original mixture.

If 5.6 litres of hydrogen and 22.4 litres of oxygen react in a vessel to form water then the mass of water formed will be?

If 5.6 litres of hydrogen and 22.4 litres of oxygen react in a vessel to form water then the mass of water formed will be?

90 gm mixture of H_(2) and O_(2) is taken In stoichiometric ratio and gives H_(2)O with 50% yield. The produced mass of H_(2)O (in gm) is :

16gm of oxygen (O_(2)) and 3gm of hydrogen (H_(2)) are present in a vessel at 0^(@)C and 760mm of Hg pressure.Volume of the vessel is

16gm of oxygen and 3gm of hydrogen are present in a vessel at 0^@C and 760mm of Hg pressure. Volume of the vessel is

A 50 gm sample which may contain either (H_(2)S)_(4) or SO_(3) or any combination of the two is mixed with 9 gm of water. The maximum oleum labelling possible of the sample formed can be:
