Answer:
77.14 atm of pressure should be of an acetylene in the tank.
Explanation:
[tex]2C_2H_2+5O_2\rightarrow 4CO_2+2H_2O[/tex]
According to reaction, 2 moles of acetylene reacts with 5 moles of oxygen.
Moles of oxygen=[tex]n_1[/tex]
Moles of acetylene =[tex]n_2[/tex]
[tex]\frac{n_1}{n_2}=\frac{5 mol}{2 mol}=\frac{5}{2}[/tex]
Volume of large tank with oxygen gas, [tex]V_1 = 5.00 L[/tex]
Pressure of the oxygen gas inside the tank = [tex]P_1=135 atm[/tex]
[tex]RT=\frac{P_1V_1}{n_1}[/tex] ..[1]
Volume of small tank with acetylene gas ,[tex]V_2= 3.50 L[/tex]
Pressure of the acetylene gas inside the tank = [tex]P_2=?[/tex]
[tex]RT=\frac{P_2V_1}{n_2}[/tex] ..[2]
Considering both the gases having same temperature T, [1]=[2]
[tex]\frac{P_1V_1}{n_1}=\frac{P_2V_2}{n_2}[/tex]
[tex]P_2=\frac{P_1V_1\times n_2}{V_2\times n_1}[/tex]
[tex]=\frac{135 atm\times 5.00 L\times 2}{3.50 L\times 5}=77.14 atm[/tex]
77.14 atm of pressure should be of an acetylene in the tank.
The study of chemicals and bonds is called chemistry. There are two types of elements are there and these are metals and nonmetals.
The correct answer is 77.14atm
What are moles?
- The mole is the base unit of the amount of substance in the International System of Units.
- It is defined as exactly 6.02214076×10²³ elementary entities, which may be atoms, molecules, ions, or electrons.
According to the question, the balanced reaction is
[tex]2C_2H_2+5O_2------>4CO_2+ 2H_2O[/tex]
Moles will be:- [tex]\frac{5}{2} = 2.5[/tex]
The ideal equation is
[tex]RT= \frac{P_1V_1}{n_1} \\\\RT= \frac{P_2V_2}{n_2} \\\\\\= \frac{P_1V_1}{n_1} = \frac{P_2V_2}{n_2} \\[/tex]
Hence, the value of P will be
[tex]P_2 =\frac{135*5*2}{3.5*5} \\[/tex]
The value of P will be 77.14atm
Hence, the correct answer is 77.14.
