Do you know what each item in the central hazardous waste storage area is for?

- Bucket liner: a second layer of protection in the hazardous waste containers; they should be sealed with a knot.

- Hazardous bucket label: identifies facility and waste information and must be placed on used hazardous waste containers.

- Zip-tie tags: these are used to close and label bucket liners.

- Chemical bags: plastic bags used to store hazardous waste. They have a zip-type closure and should only store one hazardous waste item.

- Hazardous waste management chart: a job aid which displays how to determine a spill category and how to store hazardous waste until it is picked up.

Explanation:

Hello,

Hazardous waste is a type of waste that could be harmful for the health or the environment . Such waste could exhibit the following threats: ignitability , reactivity , corrosivity  and toxicity

Hazardous wastes may be found in gaseous, liquid or solid forms. They can not be disposed of by typical methods like other by-products of our daily life. Based on the physical state of the waste, treatment and solidification processes might be required.

For the given options on the attached picture, each items match as follows:

- Bucket liner: a second layer of protection in the hazardous waste containers; they should be sealed with a knot.

- Hazardous bucket label: identifies facility and waste information and must be placed on used hazardous waste containers.

- Zip-tie tags: these are used to close and label bucket liners.

- Chemical bags: plastic bags used to store hazardous waste. They have a zip-type closure and should only store one hazardous waste item.

- Hazardous waste management chart: a job aid which displays how to determine a spill category and how to store hazardous waste until it is picked up.

n2(g) + 3h2-> 2nh3(g)   this is the balanced equation

note the mole ratio between n2, h2 and nh3.   it is 1 : 3 : 2   this will be important.

moles n2 present = 28.0 g n2 x 1 mole n2/28 g = 1 mole n2 present

moles h2 present = 25.0 g h2 x 1 mole h2/2 g = 12.5 moles h2 present

based on mole ratio, n2 is limiting in this situation because there is more than enough h2 but not enough n2.

moles nh3 that can be produced = 1 mole n2 x 2 moles nh3/mole n2 = 2 moles nh3 can be produced

grams of nh3 that can be produced = 2 moles nh3 x 17 g/mole = 34 grams of nh3 can be produced

note:   the key to this problem is recognizing that n2 is limiting, and therefore limits how much nh3 can be produced.
