Answer:
Sample response:
The costs of using both renewable and nonrenewable resources depend on the extent of the use. If renewable resources are managed wisely, the use of the resource will not exceed the rate at which it is replenished. In this instance the cost of using renewable resources can be minimized, if not entirely eliminated. The cost of using nonrenewable resources is harder to minimize because nonrenewable resources cannot be replenished at the rate at which they are used. The environmental impact of using nonrenewable resources such as fossil fuels is greater than just the loss of the resource itself. Other impacts such as acid rain, global warming, and atmospheric pollution can result from the use of nonrenewable resources.

Answer: 1.875 moles
Explanation:
2 NaN3(s) → 2 Na(s) + 3 N2(g)
From the equation above, Sodium azide has a chemical formula of NaN3 while nitrogen gas has a chemical formula of N2.
Therefore, If on decomposition
2 moles of NaN3 produce 3 moles of N2
1.25 mol of NaN3 produce Z moles of N2
To get the value of Z, cross multiply
Z x 2 moles = 3 moles x 1.25 moles
2 moles•Z = 3.75 moles²
Divide both sides by 2 moles
2 moles•Z/2 moles = 3.75 moles²/2 moles
Z = 1.875 moles
Thus, 1.875 moles of N2 are produced by the decomposition of 1.25 mol of sodium azide
