Step-by-step explanation:
a. the bond between the oxygen and hydrogen atoms is the Polar covalent bonds .
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 .
