If water sample are taken from sea, rivers or lake, they will be found to contain hydrogen and oxygen in the approximate ratio of `1 : 8`. This indicates the law of :

In the reaction between hydrogen and oxygen gives water vapour, the ratio of volumes is 2:1:2 . This illustrates the law of

Hydrogen and oxygen combine in the ratio of 1:8 by mass of form water.

An organic compound contains carbon, hydrogen, oxygen and nitrogen in the weight ratio 3:1:8:3.5 . Calculate its empirical formula.

The ratio of molecular weight of Hydrogen and Oxygen in water is 1:8. Set up an equation between Hydrogen and Oxygen and draw its graph. From the graph find the quantity of Hydrogen if Oxygen is 12 grams. And quantity of oxygen if hydrogen is 3/2 gms.?

The ratio of molecular weight of hydrogen and oxygen in water is 1 : 8. (The relation between hydrogen and oxygen in linear equations in two variables is). If the quantities of hydrogen and oxygen are ‘x’ and ‘y’.

An oxygen cylinder of volume 30 litres has an initial gauge pressure of 15 atm and a temperature of 27 ^(@)C . After some oxygen is withdrawn from the cylinder, the gauge pressure drops to 11 atm and its temperature drops to 17^(@)C . Estimate the mass of oxygen taken out of the cylinder ( R= 8.31 J mol^(-1) K^(-1) . molecular mass of O_(2) = 32 u ).
