10 ml of hydrocarbon requries 55 ml of oxygen for complete combustion producing 40 ml of CO_(2) . The formula of the hydrocarbon is:

A cylinder contains either ethylene or propylene 12 ml of gas required 54 ml of oxygen for complete combustion. The gas is

12 ml of a mixture of alkane and alkene having same number of carbon atoms requires exactly 57 ml of oxygen for complete combustion. The name of hydrocarbons if CO_2 formed is 36 ml are

10 mL of a certain hydrocarbon require 25 mL of oxygen for complete combustion and the volume CO_(2) of product is 20 mL. What is the formula of hydrocarbon ?

40 ml of gaseous mixture of CO and ethyne is mixed with 100 ml of O_2 and burnt. The volume of gases after combustion is 105 ml. The composition of the original mixture is

100ml of a mixture of CH_(4) and C_(2)H_(4) were exploded with excess of oxygen. After explosion and cooling, the mixture was treated with KOH , where a reduction of 165 ml was observed. Find the composition of the mixture taken ?

A mixture of H_(2)SO_(4) and H_(2)C_(2)O_(4) (oxalic acid ) and some inert impurity weighing 3.185 g was dessolved in water and the solution made up to 1litre. 10 mL of this solution required 3 mL of 0.1 N NaOH for complete neutralization. In another experiment 100 mL of the same solution in hot condition required 4 mL of 0.02 M KMnO_(4) solution for complete reaction. The mass % of H_(2)SO_(4) in the mixture was:

100 mL of a sample of hard water requires 25.1 mL of 0.02 N H_(2)SO_(4) for complete reaction, The hardness of water ( density 1g//mL) is:

A mixture of H_(2)C_(2)O_(4) and NaHC_(2)O_(4) weighing 2.02 g was dissolved in water and the solution made upto one litre. 10 mL of this solution required 3.0 mL of 0.1 N NaOH solution for complete neutralization. In another experiment 10 mL of same solution in hot dilute H_(2)SO_(4) medium required 4 mL of 0.1N KMnO_(4) for complete neutralization. Calculate the amount of H_(2)C_(2)O_(4) and NaHC_(2)O_(4) in mixture.
