Explanation:
Hello, at first the moles of oxygen gas are required:
Now, based on the ideal gas equation, we solve for the temperature:
Best regards.
Answer:
The volume of hydrochloric acid increases.
Explanation:
- Le Châtelier's principle states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.
- Increasing the volume of water vapors:
will increase the the concentration of the products side, so the reaction will be shifted to the left side (backward) to suppress the increase in the concentration of water vapors by addition.
So, The volume of hydrochloric acid increases, the rate of backward reaction increases, the rate of forward reaction decreases, and the volume of chlorine decreases.
<em>So, the right choice is: The volume of hydrochloric acid increases.</em>

Answer:
18moles of H20
Explanation:
C5H12 + 8O2 —> 5CO2 + 6H2O
From the balanced equation,
1mole of C5H12 were consumed to produce 6moles of H2O.
Therefore, if 3 moles of C5H12 were consumed, it will produce = 3 x 6 = 18moles of H20
The <u>actual yield of iron (Fe)</u> in moles is <u>0.207 mol.</u>
Why?
Since we know the <u>chemical equation</u>, and how much Fe is produced, we can calculate the actual yield of iron in moles using the following equation:
From the statement, we know that there are <u>11.6 g of Fe.</u>
We also know the molar mass of the Fe which is:
Now, calculating we have:
Hence, we have that the<u> </u><u>actual yield of iron (Fe)</u> in moles is<u> </u><u>0.207 mol.</u>
Have a nice day!
