Answer:
- 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.
Best regards.
Answer: at the temperature of the experiment is 0.56.
Explanation:
Moles of = 0.35 mole
Moles of = 0.40 mole
Volume of solution = 1.00 L
Initial concentration of =
Initial concentration of =
Equilibrium concentration of =
The given balanced equilibrium reaction is,
Initial conc. 0.35 M 0.40 M 0 M 0M
At eqm. conc. (0.35-x) M (0.40-x) M (x) M (x) M
Given: (0.35-x) = 0.19
x= 0.16 M
The expression for equilibrium constant for this reaction will be,
Now put all the given values in this expression, we get :
Thus at the temperature of the experiment is 0.56.
