Pressure of the nitrogen gas is 2290 kPa.

<u>Explanation:</u>

Using the ideal gas equation, we can find the pressure of the gas using the equation as,

PV = nRT

Where P is the pressure = ?

V is the volume = 3,456 ml = 3.456 L

n is the number of moles = $\frac{given mass}{molar mass}  = $\frac{45.2g }{14 g/mol}  = 3.2 mol

R is the gas constant  = 0.08205 L atm  K⁻¹ mol⁻¹

T is the temperature = 25 + 273 = 298 K

Now, rewriting the equation, we will get,

P = $\frac{nRT}{V}

= $\frac{3.2 \times 0.08205\times 298 K }{3.456 L}

= 22.6 atm

Now Pressure in 22.6 atm is converted as 2290 kPa.

what concept from chemistry was the most challenging and why? what can you do to learn more about this concept as you progress t
qwelly [4]

The most difficult concept will be the concept of patient drug tolerance because there are many drugs that have different side effects for different patients. Therefore, it is necessary to understand the response of certain drugs to different patients. This will help avoid wrong drug combinations. This can cause side effects.

To learn more about this concept, you need to do your homework on these different drugs and the tolerance reactions you may experience, and attend some drug tolerance seminars, where the speaker will give you more ideas . And a further explanation of the concept.

Another topic in chemistry that is most tough to understand is moles. We can understand this concept by understanding the fact mole is an amount of a substance which may be atoms, molecules, ions, etc which have exactly 6.02214076 * 1023 'elementary entities' of the substance.

Consider the reaction: AB As the reaction proceeds, the concentration of A drops from 0.625 M to 0.100 Min 11.6 seconds. What is
prisoha [69]

Answer:

0.045 M/s

Explanation:

Given:

Initial concentration of A = 0.625 M

Final concentration of A = 0.100 M

Total time taken for the change of concentration = 11.6 seconds

The average rate of reaction is calculated as:

= \frac{\textup{Change in concentration of A}}{\textup{Time taken for the change}}

on substituting the respective values, we get

= \frac{0.625-0.100}{\textup{11.6}}

or

The average rate of reaction = 0.045 M/s

Mashcka [7]

Answer:

Atomic Oribal

Explanation:

There are four basic types of electron orbitals – s, p, d, and f. (Visual representations can be found in the tutorial above.) The s subshell is a spherical orbital which can contain up to two electrons. Each energy level has one s subshell.
