Resources can be renewable or nonrenewable based on their replenishing power. Some renewable energy sources are wind, water, and solar energy, and nonrenewable is natural gas, coal, diesel, etc.

<h3>What are renewable and non-renewable sources?</h3>

Renewable resources are the things that can get refilled when they are utilized for the purpose. Nonrenewable resources are the sources that have a short existing period of life.

Some examples of renewable resources are wind, air, groundwater, solar energy, timber, soil, etc. Some nonrenewable resources are coal, petrol, diesel, natural gas, etc.

Renewable resources are present for an infinite time period while the non-renewable get depleted when excessively used. Renewable has less environmental impact than nonrenewable sources as they lack harmful chemicals that causes the environmental imbalance.

Therefore, nonrenewable resources are harmful to the environment compared to renewable resources.

Explain why aluminum does not react with potassium nitrate (KNO3) although it reacts with copper nitrate
Ratling [72]

Answer:

Potassium is more reactive than aluminium, so no reaction takes place. But aluminium is more reactive than copper, so it replaces the copper in copper nitrate

<h3>Explanation:</h3>

More reactive metal compound + less reactive metal

-> no reaction

However

Less reactive metal compound + more reactive metal

-> more reactive metal compound + less reactive metal

This is called substitution reaction where the more reactive metal replaces the less reactive metal in the compound.
