Consider the following balanced equation for the following reaction:
Sidana [21]

<u>Answer:</u> The actual yield of the carbon dioxide is 47.48 grams

<u>Explanation:</u>

For the given balanced equation:

15O_2(g)+2C_6H_5COOH(aq.)\rightarrow 14CO_2(g)+6H_2O(l)

To calculate the mass for given number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

Theoretical moles of carbon dioxide = 1.30 moles

Molar mass of carbon dioxide = 44 g/mol

Putting values in above equation, we get:

1.30mol=\frac{\text{Theoretical yield of carbon dioxide}}{44g/mol}\\\\\text{Theoretical yield of carbon dioxide}=(1.30mol\times 44g/mol)=57.2g

To calculate the theoretical yield of carbon dioxide, we use the equation:

\%\text{ yield}=\frac{\text{Actual yield}}{\text{Theoretical yield}}\times 100

Theoretical yield of carbon dioxide = 57.2 g

Percentage yield of carbon dioxide = 83.0 %

Putting values in above equation, we get:

83=\frac{\text{Actual yield of carbon dioxide}}{57.2}\times 100\\\\\text{Actual yield of carbon dioxide}=\frac{57.2\times 83}{100}=47.48g

Hence, the actual yield of the carbon dioxide is 47.48 grams

Which process lets convection plays a role in the water cycle?
Sergio039 [100]
The best and most correct answer among the choices provided by your question is the third choice or letter C. 

Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it. Convection plays a role in the water cycle when "<span> gases cycle up and down based on air pressure."

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

the smell spreads immediately after you burn agarbatti in this example what is your condition about intermolecular force
Sloan [31]
Intermolecular force for solids is high. Whereas low in gases. The smell of agarbatti spreads immediately because the molecules of air diffuses very fastly.
