Answer: Option (d) is the correct answer.
Explanation:
Atomic number of carbon is 6 and its electronic distribution is 2, 4. Therefore, in order to become stable and completely fill its octet carbon readily share its valence electrons with another atom.
For example, 
A carbon atom is also able to form a double double with valence electrons of other atom.
Thus, we can conclude that a carbon atom has a strong tendency to share electrons.
Answer:
BBB millipedes have two sets of legs on each segment.
Explanation:
The energy change if 84.0 g of CaO react with excess water is 98KJ of heat is released.
calculation
heat = number of moles x delta H
delta H = - 65.2 Kj/mol
first find the number of moles of CaO reacted
moles = mass/molar mass
the molar mass of CaO = 40 + 16= 56 g/mol
mass = 84 g
moles therefore = 84 g/56 g/mol =1.5 moles
Heat is therefore = 1.5 moles x -65.2 = - 97.8 Kj = -98 Kj
since sign is negative the energy is released
