For the following questions consider a water molecule, H2O. a. What type of bond is formed between the oxygen and the hydrogen atoms? b. Describe how these bonds form. c. Explain why there are two hydrogen atoms for each oxygen atom.

b. Polar hydrogen bond - They are polar in nature due to the unequal sharing of the electrons , hydrogen has a partial positive charge and the oxygen has a partial negative charge .

The bonds that are covalent in nature are responsible for a new molecule formation , but hydrogen bonds can not .

c. According to the balanced chemical equation , i.e. ,

1 O₂ + 2 H₂ → 2 H₂O

One molecule of oxygen reacts with two molecules of hydrogen to give the product as water .

This is about type of bonds between elements that make water molecules.

A) Polar Covalent Bond

B) Because of unequal sharing of valence electrons

C) Because left hand side must balance out with right hand side

A. The type of bond that will be formed between the oxygen and hydrogen atoms of the water molecule is called Polar covalent bond.

B. Polar covalent bond is formed between the hydrogen and oxygen because the sharing of valence electrons between them is unequal since hydrogen has 1 valence electron and oxygen has 6 valence electrons.

C. To solve this, we need to write a balanced equation;

1(O₂) + 2H₂ → 2H₂O

In chemical equations, the left hand side must balance out with the right hand side. Thus, that's why the right hand side has 2 hydrogen atoms for one oxygen atom.
