Consider the following balanced equation for the following reaction:
balandron [24]

<u>Answer:</u> The amount of carbon dioxide formed in the reaction is 47.48 grams

<u>Explanation:</u>

For the given chemical equation:

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

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

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

Percentage yield of carbon dioxide = 83 %

Theoretical yield of carbon dioxide = 1.30 moles

Putting values in above equation, we get:

83=\frac{\text{Actual yield of carbon dioxide}}{1.30moles}\times 100\\\\\text{Actual yield of carbon dioxide}=\frac{1.30\times 83}{100}=1.079moles

To calculate the number of moles, we use the equation:

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

Molar mass of carbon dioxide = 44 g/mol

Moles of carbon dioxide = 1.079 moles

Putting values in above equation, we get:

1.079mol=\frac{\text{Mass of carbon dioxide}}{44g/mol}\\\\\text{Mass of carbon dioxide}=(1.079mol\times 44g/mol)=47.48g

Hence, the amount of carbon dioxide formed in the reaction is 47.48 grams

Determine the moles of oxygen gas (O2) needed to completely react with 1.975 moles of hydrogen gas (H2).
Pavlova-9 [17]

Answer:

0.9875 mole O₂

Explanation:

Rxn => H₂ + ¹/₂O₂ => H₂O

from above reaction, 1 mol H₂ requires ¹/₂ mol O₂ then 1.975 mol H₂ requires   ¹/₂(1.975 mol)O₂ or 0.9875 mol O₂.
