What may indicate that the pressure within a container is increasing and that container failure may be imminent?

brilliants [131]

Answer:

An increase in the intensity of sounds or fire issuing from a relief valve.

<h2>What does "contents under pressure" mean?</h2>

Propane serves as the propellant in all aerosols. R-12, a Freon that was the previous propellant, has been outlawed because it harms the ozone layer above the poles. Propane and R-12 share the same pressure-temperature characteristics.

Propane's boiling point is quite low. It desires a boil-off at ambient temperature. And it continues to do so until the pressure inside a closed container rises to roughly 150 psi (give or take depending on temperature), at which time the boiling point is raised high enough to cause the substance to stop boiling.

"Contents Under Pressure" is exactly what the notice indicates. Paint, hairspray, lubricant, wasp and hornet spray, among other liquids, can be found within an aerosol can, which is a pressure vessel. By inspecting the bottom, you may determine whether a vessel is a pressure vessel. If it is dished in like a bowl, it has the same pressure-holding end as a huge propane tank, with the exception that the curve on the latter has an outward orientation. On aerosol canisters, it is inward because they must sit upright for ease. A circular bottom just cannot accomplish that. But the top resembles an outer hemisphere more or less.

Thank you,

If you had excess chlorine, how many moles of of aluminum chloride could be produced from 25.0 g of aluminum? Express your answe

m_a_m_a [10]

Answer:

A. From 25,0 g of aluminium you will produce 0,927 moles of aluminium chloride

B. From 30,0 g of chlorine gas you will produce: 0,282 moles of aluminium chloride

Explanation:

a. The reaction that you have in this problem is:

3 Cl₂ + 2 Al → 2 AlCl₃

25,0 g of aluminium are:

25,0 ₓ $\frac{1mole}{26,98g}$ = 0,927 moles

As Al:AlCl₃ ratio is 1, from 25,0 g of aluminium you will produce: 0,927 moles of aluminium chloride

b. 30,0 g of chlorine gas are:

30,0 ₓ $\frac{1mole}{70,90g}$ = 0,423 moles of Cl₂

As Cl₂:AlCl₃ ratio is ³/₂:

0,423 moles of Cl₂ ₓ $\frac{2 molesAlCl_3}{3 molesCl_2}$ = 0,282 moles of aluminium chloride

Thus, from 30,0 g of chlorine gas you will produce: 0,282 moles of aluminium chloride

I hope it helps!
