Answer: Option (b) is the correct answer.
Explanation:
A covalent bond is defined as the bond that is formed by sharing of electrons between the two chemically combining atoms.
For example, in a molecule.
As the valency of each carbon atom is 4, valency of each hydrogen atom is 1, and valency of each oxygen atom is 2.
So, in each one outermost electron of carbon atom is shared by each one outermost electron of hydrogen atom.
The fourth outermost electron is shared by one outermost electron of oxygen atom and the other outermost electron of oxygen atom is shared by the hydrogen atom of -OH.
Hence, we can conclude that there are total 5 covalent bonds present in the formation of methyl hydroxide ( or methanol).

Answer: The correct answer is mass number.
Explanation:
An isotope is a chemical compound of the same element which only differ in the number of neutrons. The number of protons and electrons remain same for two isotopes. This means isotopes have different mass number but have same atomic number.
When we write an isotope, the number at the end of the isotope's name is the mass number.
When writing an isotope: Chlorine-35, the number 35 represents the atomic mass and not atomic number.
Hence, the correct answer is mass number.
If the burner doesn't light after several strikes, turn the gas off at the source. Verify that you are generating sparks when striking the striker, and check that the barrel is all the way down and the needle valve is open by the specified amount. If these check out, the problem may be insufficient gas flow.
