A sample of 1.00 moles of oxygen at 50°C and 98.6 kPa, occupies what volume?

Chemistry
1 answer:
enyata [817]3 years ago
5 0

Answer:

27.22 dm³

Explanation:

Given parameters:

number of moles = 1 mole

temperature= 50°C, in K gives 50+ 273 = 323K

Pressure= 98.6kpa in ATM, gives 0.973 ATM

Solution:

Since the unknown is the volume of gas, applying the ideal gas law will be appropriate in solving this problem.

The ideal gas law is mathematically expressed as,

Pv=nRT

where P is the pressure of the gas

V is the volume

n is the number of moles

R is the gas constant

T is the temperature

Input the parameters and solve for V,

0.973 x V = 1 x 0.082 x 323

V= 27.22 dm³

Summarize the relationship between an electron's energy level and its location in an atom
FromTheMoon [43]

Answer:

The further an electron is from the nucleus. the greater its energy level.

Explanation:

When an electron is close to the nucleus, it is at as low an energy level as it can get.

We must put energy into an electron to pull it away from the attraction of a nucleus.

So, electrons that are further from the nucleus are at higher energy levels.
