Question

Name the elements water isade of. What are the valencies of these elements ? Work out the chemical formula for water.​

Answer 1

Answer:

water is made with the mixture of hydrogen and carbon..the valency of hydrogen is 1 and oxygen is 2. so, the formula by cross over method is H2O.. Water is made of two elements. Hydrogen and Oxygen.

Answer 2

Water is made with the mixture of hydrogen and carbon..the valency of hydrogen is 1 and oxygen is 2. so, the formula by cross over method is H2O.. Water is made of two elements. Hydrogen and Oxygen.

Chemical formula of water:-

The molecular formula for water is H2O. One molecule of water consists of one oxygen atom covalently bonded to two hydrogen atoms. There are three isotopes of hydrogen. The usual chemical formula for water assumes the hydrogen atoms consist of the isotope protium (one proton, no neutrons)
