Question

Hydrogen can be created by _____ water. If the activation energy is reduced, hydrogen can be produced with a renewable energy source. This renewable energy source is ____.

Answer 1

Hydrogen can be created by decomposed water and solar energy.

Step-by-step explanation:

Hydrogen can be created by a process called electrolysis in which the water is decomposed due to the pass of an electric current. In order to split water, a potential difference of 1.23 volts is required. On the other hand, hydrogen can also be obtained through a renewable energy source which is solar energy. This process is also carried out by the electrolysis but, in this case, the energy used comes from the sun.

Answer 2

Answer 1) Decomposing (Electrolysis)

Explanation :

Hydrogen can be created by decomposing water. Electrolysis which is a method of passing electricity from the water and obtaining the products as hydrogen and oxygen is done by decomposition of water. The water molecule is broken down into its constituents.

Answer 2) Solar energy

Explanation :

If the activation energy is reduced, hydrogen can be produced with a renewable energy source. This renewable energy source is Solar energy.

Solar energy from the sun can be used to lower the energy of activation during the decomposition of water. Solar energy is a renewable energy source as it comes from the sun and is replenish-able unlike fuels which cannot be replenished. The solar energy can be collected and utilized for production of hydrogen.
