Carbon dioxide gas occupies a volume of 20.0 L at 308K and 2.30 atm. What volume would it occupy at 416 K and 5.40 atm?

Brrunno [24]

Answer : The final volume of gas is, 11.5 L

Explanation :

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

where,

$P_1$ = initial pressure of gas = 2.30 atm

$P_2$ = final pressure of gas = 5.40 atm

$V_1$ = initial volume of gas = 20.0 L

$V_2$ = final volume of gas = ?

$T_1$ = initial temperature of gas = 308 K

$T_2$ = final temperature of gas = 416 K

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

$\frac{2.30atm\times 20.0L}{308K}=\frac{5.40atm\times V_2}{416K}$

$V_2=11.5L$

Therefore, the final volume of gas is, 11.5 L

sesenic [268]

Here we have to chose the correct statement which affect the discovery of the atomic number on the periodic table.

The discovery of the atomic number of the elements: C. It allowed the elements to be placed in strict order of increasing atomic number.

The use of X-ray determined the atomic number or number of electrons present in an element. The number of electrons is the basis of generate the periodic table, where the elements are arranged in terms of the number of electrons present in the atom in early stage of periodic table.

However in later the modern periodic table generated, which has group and period in terms of their property. Although the strictness on the increasing number of electrons are followed.

Dafna1 [17]

In the dark waters just below the photic zone, because of cellular respiration, the concentration of dissolved carbon dioxide is higher relative to dissolved oxygen.
In cellular respiration living organisms use oxygen and release carbon dioxide, because there is little or no light there is no photosynthesis and oxygen is little produced.
