The initial pressure of a mixture of C6H6 and an excess of H2 in a rigid vessel is 1.21 atm. A catalyst is introduced. After the
KengaRu [80]

Answer:

mole fraction of C6H6 = 0.613 atm

Explanation:

The equation for this reaction is :

          C_6H_6 _{(g)} + 3H_2_{(g)} \to C_6H_{12}_{(g)}

Initial      P₁            P₂             0

Final        0           P₂ -P₁/2      P₁

After completion of the reaction;

P₁  +  P₂  = 1.21 atm                    ----- (1)

P₂  -  P₁/2 +  P₁ = 0.839 atm

P₂ + P₁/2 = 0.839 atm          ----- (2)

Subtracting (2) from (1); we have:

P₁/2 = 0.371

P₁ = 0.742 atm

From(1)

P₁  +  P₂  = 1.21 atm

0.742 atm + P₂  = 1.21 atm

P₂  = 1.21 atm - 0.742 atm

P₂  = 0.468 atm

Thus, the partial pressure of C6H6 = 0.742 atm

∴

Partial pressure = Total pressure × mole fraction of C6H6

mole fraction of C6H6 = Partial pressure /  Total pressure

mole fraction of C6H6 = 0.742 atm / 1.21 atm

mole fraction of C6H6 = 0.613 atm

Suppose that you measure a pen to be 10.5 cm long. Convert this to meters.
Svetach [21]
If the pen is 10.5cm long, it is 0.105 meters. This can be worked out by considering that there are 100cm's in 1 meter, so you need to divide 10.5 by 100. You then move the decimal place 2 places to the right (because of the two zeros), which leads you to your answer of 0.105.

Given the following equation: 2 K + Cl2---> 2 KCl How many moles of K are needed to react with 0.5 moles of C
djverab [1.8K]

Answer:

1 mol of K

Explanation:

The reaction is:  2K  +  Cl₂  →  2KCl

2 moles of potassium react with 1 mol of chlorine to make the salt, potassium chloride

If you see the stoichiometry from reactants, 2 moles of K need 1 mol of Cl₂ to react, so 1 mol of Cl₂ needs 2 moles of K, to react too.

We can make a rule of three, to reach the answer:

1 mol of Cl₂ needs 2 moles of K to react

Then, 0.5 moles of Cl₂ must react with (0.5 . 2) / 1 =  1 mol of K

Calculate the molar concentration of 4.75 moles of NaCl in<br> 0.50 liters of water?
worty [1.4K]

Answer:

9.5 m

Explanation:

First, divide 4.75 m by the 0.50 l

4.75/0.50

This leaves you with 9.5 m
