Question

Let us perform some more decomposition reactions as given in hate Activities 1.7 and 1.8. in own words for class 10th​

Answer 1

Answer:

Electricity decomposes water into its component. Hydrogen atoms in water receive an electron from cathode electrode and form hydrogen gas. Similarly, oxygen atoms in water lose electron at the anode and form oxygen gas.

Electricity decomposes water into its component. Hydrogen atoms in water receive an electron from cathode electrode and form hydrogen gas. Similarly, oxygen atoms in water lose electron at the anode and form oxygen gas.We can explain this with the equation below.

Here you can see two molecules of hydrogen gas liberate with one molecule of oxygen. So the volume of hydrogen obtained is double the amount of oxygen.
