A tetrahedral carbon is sp3 hybridized while a linear carbon is sp hybridized.
Carbon is a chemical element with the symbol C and atomic number 6. It is a non-metal and is tetravalent. That atom donates four electrons to form a covalent chemical bond. It belongs to group 14 of the periodic table. Carbon makes up only about 0.025% of the Earth's crust.
Carbon is used in some form in almost every industry in the world. It is used as fuel in the form of coal, methane gas, and crude oil (used to make gasoline). It is used to manufacture all kinds of materials, including plastics and alloys such as steel (a combination of carbon and iron). Carbon is an essential element for all life forms on earth. Carbon uptake and release are part of all plant and animal life, whether these life forms take up carbon to help make food or release carbon as part of respiration. Carbon is in constant motion from place to place.

1 mole Ni ------------- 6.02x10²³ atoms
?? moles Ni ----------- 5x10²⁵ atoms
1 x ( 5x10²⁵ ) / 6.02x10²³ =
=> 83.05 moles
Answer: i) 
ii) 
iii) 
iv) 
v) 
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The balanced chemical reactions will be:
i)
ii)
iii)
iv)
v)
