Calculate the concentration of CO2 in water at 25 degrees Celsius when the pressure of CO2 over the solution is 4.5 atm. At 25 d
OLEGan [10]

Answer : The concentration of CO_2 is, 0.12 M

Explanation :

Using Henry's law :

C_{CO_2}=k_H\times p_{CO_2}

where,

C_{CO_2} = concentration of CO_2 = ?

p_{CO_2} = partial pressure of CO_2 = 4.5 atm

k_H = Henry's law constant  = 3.1\times 10^{-2}mol/L.atm

Now put all the given values in the above formula, we get:

C_{CO_2}=3.1\times 10^{-2}mol/L.atm\times (4.5atm)

C_{CO_2}=0.1395M\approx 0.12M

Thus, the concentration of CO_2 is, 0.12 M

Name the following structure
Paraphin [41]

Answer:

2–butyne.

Explanation:

To name the compound given above, we must determine the following:

1. Determine the functional group of the compound.

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

3. Locate the position of the functional group by giving it the lowest possible count.

4. Combine the above to obtain the name.

Thus, we shall name the compound as follow:

1. The compound contains triple bond (C≡C). Therefore, the compound is an alkyne.

2. The longest chain is carbon 4. Thus the parent is butyne.

3. The triple bond (C≡C) is located at carbon 2 when we count from either side.

4. The name of the compound is:

2–butyne
