What is the final pressure (expressed in atm) of a 3.05 L system initially at 724 mm Hg and 298 K, that is compressed to a final

Hey there!:

V1 = 3.05 L

V2 = 3.00 L

P1 = 724 mmHg

P2 = to be calculated

T1 = 298 K

T2 = 273 K

Therefore:

P1*V1  / T1  = P2*V2 / T2

P2 = ( P1*V1 / T1  )   * T2 / V2

P2 = 724 * 3.05 * 273 / 298 * 3.00

P2 = 602838.6 / 894

P2 = 674.31 mmHg

1 atm ----------- 760 mmHg

atm ------------- 674.31 mHg

= 674.31 * 1 / 760

= 0.887 atm

Hope this helps!

Which type of force occurs between two objects at a distance?
agasfer [191]

Answer:

Gravitational force of attraction.

Explanation:

When two bodies of masses 'm' and 'M' are separated by a distance 'r', then both the bodies experience a force of attraction towards each other. This force of attraction is called gravitational force. It is a weak force but it always act between two bodies that have mass.

The magnitude of the gravitational force is directly proportional to product of the masses and inversely proportional to the square of the distance between the masses.

This means that as the distance between the bodies is increases, the gravitational force between the bodies decreases and vice versa.

The gravitational force of attraction is given as:

F_g=\frac{GmM}{r^2}\\\\G\to \textrm{Universal Gravitational constant}

Consider the reaction below that has a Keq of 8.98 X 10-2. The initial concentration of A and B is 1.68 M. Calculate the equilib
DaniilM [7]

Answer:

[C] = 0.4248M

Explanation:

                   A     +     B      ⇄     2C

C(i)          1.68M      1.68M         0.00

ΔC              -x            -x             +2x

C(eq)      1.68-x       1.68-x          2x

Keq = [C]²/[A][B] = (2x)²/(1.68 - x)²= 8.98 x 10⁻²

Take SqrRt of both sides => √(2x)²/(1.68 - x)² = √8.98 x 10⁻²

=> 2x/1.68 - x = 0.2895

=> 2x = 0.2895(1.68 - x)

=> 2x = 0.4863 - 0.2895x

=> 2x + 0.2895x = 0.4863

=> 2.2895x = 0.4863

=> x = 0.4863/2.2895 = 0.2124

[C] = 2x = 2(0.2124)M = 0.4248M in 'C'

What is the IUPAC name for this molecule above?<br>with explanation step​
Lelechka [254]

Answer:

3,4–diethylheptane

Explanation:

To name the compound given in the question above, the following must be obtained:

1. Determine the functional group of the compound.

2. Determine the longest continuous carbon chain. This gives the parent name of the compound.

3. Identify the substituent groups attached to the compound.

4. Give the substituent groups the lowest possible count by naming them alphabetically.

5. Combine the above to obtain the name of the compound.

Now, we shall name the compound given in the question above as follow:

1. The compound belongs to the alkane family since it has only single bonds.

2. The longest continuous carbon chain is 7 i.e the parent name of the compound is heptane.

3. The substituent group attached to the compound is ethyl (–CH2CH3). There are two ethyl groups attached to the compound.

4. The two ethyl group is at carbon 3 and 4 (i.e number from the right to the upper branch chain).

5. The name of the compound is:

3,4–diethylheptane.

If the empirical formula for a compound is NO2 and the molecular mass is 230.05 g/mol, what is the molecular formula for the com
PilotLPTM [1.2K]

Answer: \text{N}_{5}\text{O}_{10}

Explanation:

  • The atomic mass of nitrogen is 14.0067 g/mol.
  • The atomic mass of oxygen is 15.9994 g/mol.

This means the molecular mass of nitrogen dioxide is 14.0067+2(15.9994)=46.0055 g/mol.

Dividing this molecular mass of the compound we need to find, we get that

\frac{230.05}{46.0055} \approx 5.

So, the final answer is \boxed{\text{N}_{5}\text{O}_{10}}
