Answer:

See notes on LeChatlier's Principle I gave you yesterday.

Explanation:

Remember chemical see-saw => Removing Fe⁺³ makes the reactant side of the see-saw lighter causing the balance to tilt right then shift left to establish a new equilibrium with new concentration values. Such would result in a decrease in FeSCN⁺² concentration and increases in Fe⁺³ and SCN⁻ concentrations to replace the original amount of ppt'd Fe⁺³. => Answer Choice 'B' ... Also, see attached => Concentration effects on stability of chemical equilibrium .

A sample of sulfur has a mass of 232 grams. How many moles of sulfur are in the sample? 7.24 mol of S 7.235 mol of S 8.00 mol of

galben [10]

Answer:

7.235 mol of S are in the given sample

Explanation:

Number of mol calculated as follows:

Number of mol = amount in g / molar mass

Given that amount of sulfur = 232 grams.

Molar mass of sulfur = 32.065 g/ mol

Therefore the number of S is calculated as follows:

Number of mol = 232 grams/ 32.065 g/ mol

= 7.235 mol

7.235 mol of S are in the given sample

Liquid nitrogen is cold and can be used to cool objects to -196°C. If you put the bottle of warm air in liquid nitrogen at this

shtirl [24]

Answer:

It will boil.

Literally, every liquid has a boiling point, unless it chemically decomposes before it gets to that point (which liquid nitrogen certainly doesn't). At normal atmospheric pressure, it can be 'heated' to -196 C. At that point, any heat you put into it will go into boiling liquid nitrogen into nitrogen gas. At higher pressures, the same thing will happen at a higher temperature. Once all the liquid is boiled, the gas will continue to rise in temperature as long as heat is being added.

In terms of shape and volume, how can a gas be defined ?

Gnoma [55]

Particles in a gas are far apart compared to a solid or liquid, allowing it not to have a definitive shape or volume. This also means that gases can fill any container and be easily compressed.
