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-

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?

62.5 gm of a mixture of CaCO_(3) and SiO_(2) are treated with excess of HCl and 1.1 gm of CO_(2) is produced. What is mass % CaCO_(3) in the mixture.

Similar to % labelling of oleum ,a mixture of H_(3)PO_(3) and P_(4)O_(6) is labelled as (100 +x)% where x is maximum mass of water which can reacts with P_(4)O_(6) present in 100 gm mixture of H_(3)PO_(3) and P_(4)O_(6) P_(4)O_(6) + H_(2)O rarr H_(3)PO_(3) For such a mixture of P_(4)O_(6) and H_(3)PO_(3) labelled as (100 +x)% . Value of x can lie in range of (maximum and minimum) :

Similar to % labelling of oleum ,a mixture of H_(3)PO_(3) and P_(4)O_(6) is labelled as (100 +x)% where x is maximum mass of water which can reacts with P_(4)O_(6) present in 100 gm mixture of H_(3)PO_(3) and P_(4)O_(6) P_(4)O_(6) + H_(2)O rarr H_(3)PO_(3) If such a mixture is labelled as 127 % , then mass of free P_(4)O_(6) in given 100 g mixture is :

34 gm of a mixture containing N_(2) and H_(2) in 1:3 by mole is partially coverted into NH_(3) . Calculate the molar mass of the mixture (containing remaining N_(2),H_(2) and NH_(3) formed) after reaction if it has been found that the NH_(3) formed required 0.5 moles of H_(3)PO_(4) for complete neutralization 3NH_(3)+H_(2)PO_(4)rarr(NH_(4))_(3)PO_(4) Write nearest integral value.

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
