Answer:
carbon has four unpaired electrons in its valence shell . hydrogen having one unpaired electron in its valence shell comes to bond with carbon by sharing a pair of electrons .since carbon needs 4 electrons to be stable, 4 hydrogen atoms take part in the bond . It's a covalent bond because the difference between the electronegativity of carbon and hydrogen is quite small .
Answer:
Number of protons equals the number of neutrons
Mass (kg) = force (N) / acceleration (m/s).

Answer:
1)objects in parallel experience the same potential difference.Therefore the voltmeter is connected in parallel to the object for which we want to calculate the P.d
2}objects in series in a circuit experiance
the same current thus they have to be in series to have the same exact current
