At high temperature, carbon reacts with water to produce a mixture of `CO` and `H_(2)`.
`C + H_(2) O overset ("Heat heat")rarr CO + H_(2)`
`CO` is separated from `H_(2)` and then used to separate `Ni` from `CO` by forming a volatile compound, nickel tetracarbonyl `(Ni(CO)_(4))`.
`Ni + 4CO rarr Ni(CO)_(4)`
(a) Formation of volatile `Ni(CO)_(4)` and its subsequent heating give pure `Ni`. Name the process involved.
(b) How many moles of `Ni(CO)_(4)` could be obtained from `CO` produced by the reaction of `75.0 g` is carbon ?

Explanation

### Step-by-Step Solution

**(a)** The process involved in the formation of volatile nickel tetracarbonyl `(Ni(CO)₄)` and its subsequent heating to yield pure nickel is known as the **Mond Process**. This process is used for the purification of nickel by forming a volatile compound that can be decomposed to obtain pure nickel.

**(b)** To calculate how many moles of `Ni(CO)₄` could be obtained from the carbon monoxide produced by the reaction of `75.0 g` of carbon, we follow these steps:

1. **Determine the moles of carbon (C)**:
- Molar mass of carbon (C) = 12 g/mol
