The height of the bin is 29.9m.
The quantity of space enclosing a three-dimensional shape's exterior is its surface area.
The total surface area of the cylinder formula is simply the sum of the base surface area and the lateral surface area.
The radius of the cylinder, r = 5m
Surface area = 1099 m²
∴ A = 2πrh + 2πr²
Therefore, the height of the bin is 29.9m.

Answer:
a) No molecules of hydrogen
b) four molecules of ammonia
c) four left molecules of nitrogen.
Explanation:
The balanced reaction between nitrogen and hydrogen molecules to give ammonia molecules is:
Thus one molecule of nitrogen will react with three molecules of hydrogen to give two molecules of ammonia.
We have six molecules of each nitrogen and hydrogen in the closed container and they undergo complete reaction it means the limiting reagent is hydrogen. For six molecules of nitrogen, eighteen molecules of hydrogen will be required.
So six molecules of hydrogen will react with two molecules of nitrogen to give four molecules of ammonia.
The product mixture will have
a) No molecules of hydrogen
b) four molecules of ammonia
c) four left molecules of nitrogen.
