Water can be separated into hydrogen and oxygen gas via electrolysis in the following equation. 2H20 -> 2H2 +O2 What type of reaction is this.

D: Decomposition Reaction

Explanation:

A decomposition reaction is a reaction in which a compound breaks down into two or more simpler substances.

The general form of a decomposition reaction is: AB -> A+B.

You just split the nonmetals into a molecule depending on the element.

But they are rules though when doing this reaction. If a element is a diatomic molecule, then you would write a 2 in the subscript.

Diatomic molecules contain two atoms that are chemically bonded

Now let us go back to this problem: 2H2O -> 2H2 + O2

So water or 2H2O split into 2H2 and O2 because hydrogen and oxygen are diatomic elements.

That is how you write the product of a decomposition reaction.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
