Hint: Try to recall that a molecule of water is made up of two hydrogen atoms and one oxygen atom and the bond between hydrogen and oxygen atom is referred to as covalent bond. Now, by using this you can easily find the correct option from the given ones.
Complete answer:
* It is known to you that a water molecule is made up of matter. It contains atoms. There are two hydrogen atoms and one oxygen atom.
* Water has two chemical components, oxygen and hydrogen, which gives us the formula .
* When hydrogen gas is burned in presence of oxygen gas, then water is formed. The reaction is as follows: .
* The reaction of hydrogen with oxygen to form water is a very exothermic reaction showing that water is a much more stable molecule than hydrogen and oxygen.
Therefore, from above we can easily conclude that option C is the correct option to the given question.
Additional information:
Other methods by which water is formed synthetically are as follows:
* By elimination reactions from molecules that contain hydrogen and oxygen in the right proportion.
* By catalytically combining oxygen and hydrogen to provide power sources in non-polluting fuel cells that produce only water as the waste product.
Note:
It should be remembered that in a liquid state, water molecules are held together by intermolecular hydrogen bonding. Each oxygen atom can form two H-bonds by using each of its two lone pair of electrons. Thus, in a liquid state water exists as an associated liquid.
