4 0

Answer:

The least similar to a real gas found in the environment would be B.

Explanation:

Standard Ambient Temperature/Pressure (SATP) is at 298.15K and 101.3kPa. It describes standard conditions and is often used for measuring gas density and volume using the Ideal Gas Law. The values least similar to theses ones would be the least similar in the gases in the environment.

Do you know what each item in the central hazardous waste storage area is for?
Sonbull [250]

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.

How much heat is produced by combustion 125 g of methanol under standard state condaitions?
timurjin [86]

Answer:

Explanation:

For the reaction ,

2CH₃OH   +   3O₂   →   2CO₂  +  4 H₂O

For the above reaction ,

the change in enthalphy is calculated as

Δ Hrxn = Δ H°f (products) - Δ H°f (reactants)

In case the compound is in its standard state , enthalphy of formation is zero

Hence ,

for the above reaction ,

ΔHrxn =( 2 * Δ H° (CO₂ ) + 4 * Δ H° (H₂O )) - [ ( 2 *Δ H°CH₃OH  ) + (3 * Δ H° O₂ )]

Δ H° (CO₂ ) = -393.5kJ /mol

Δ H° (H₂O ) = - 241.8 kJ /mol

Δ H°CH₃OH = -239.2kJ /mol

Δ H° O₂  = 0

putting the corresponding values ,

ΔHrxn =( 2 * -393.5kJ /mol + 4 *- 241.8kJ /mol) - [ ( 2 *-239.2kJ /mol  ) + (3 *0 )

ΔHrxn = -1275.8 kJ /mol

Moles of methanol,

Moles is denoted by given mass divided by the molecular mass ,  

Hence ,  

n = w / m

n = moles ,  

w = given mass ,  

m = molecular mass .

From the question ,

w = 125 g

as we know ,

m = 32 g /mol

n = 125 g /  32 g /mol = 3.906 mol

From , the reaction , 2 mol produces -1275.8 kJ /mol heat ,

Now using unitary method ,

1 mol produces = -1275.8 kJ /mol / 2  heat ,

3.906 mol produces = -1275.8 kJ /mol / 2 * 3.906 heat

3.906 mol produces = 249.7 kJ
