is a resource that can be easily recovered through natural process and can be used again and again. Water, air, and sunlight are some of the renewable energy resources. Even though these resources are in abundance, proper measures should be taken to prevent overexploitation of these resources. - Answer-Renewable natural resources are those resources that take time for Earth to replenish through its natural processes. Humans use these natural resources faster than Earth can replenish them. F...

SALTS All solid salts consist of positive and negative ions, and some of them contain water molecules as well. The water in a lattice is called water of crystallisation. One mole of a hydrated salt always has a certain number of moles of water of crystallisation shown in the formula. For example, hydrated copper sulphate (CuSO4.5H2O) has five moles of water for each mole of the salt. GROUP 1 Group 1 elements are alkali metals. They are metals that are usually stored under oil or argon to s...
