1 answer:
Following reaction shows the preparation of Nitrile from Amide. In this reaction Thionyl Chloride (SOCl₂)is reacted with Amide, which produced nitrile along with SO₂ and HCl gas. The importance of this reaction is the removal of byproducts (i.e SO₂ and HCl). As both SO₂ and HCl are gases so no extra workup is required to remove them. The mechanism of reaction is as follow,

The cost of painting the traffic sign of 7.065 square feet is approximately equal to 25 dollar.
<u>Explanation:</u>
The cost of painting the circular traffic sign is given as 3.50 dollar per square feet. The diameter of the traffic sign is 36 inch, then its radius will be inches.
But as the cost is given in unit of feet, we have to convert the radius from inches to feet.
1 inches = 0.0833 feet
18 inches = 18 × 0.0833 feet
So, the radius of the traffic sign will be approximately equal to 1.5 feet.
The area of the traffic sign will be square feet.
So, if the cost of painting 1 square feet of traffic sign is 3.50 dollar, then
cost of painting 7.065 square feet of traffic sign = 3.50 × 7.065 = 24.7 dollar.
Thus, the cost of painting the traffic sign of 7.065 square feet is approximately equal to 25 dollar.
