Explanation:
Complete question
Write a balanced chemical equation to represent the combustion of CH3CH2CH2CH2CH3
Solution
The given compound is pentane
C5H12
The empirical equation representing combustion of pentane is
C5H12 + O2 --> CO2 + H2O
We will first balance the carbon atoms
C5H12 + O2 --> 5CO2 + H2O
Now we will balance the Hydrogen molecule
C5H12 + O2 --> 5CO2 + 6H2O
Now we will balance the oxygen molecule
C5H12 + 8O2 --> 5CO2 + 6H2O
Answer:
Percent yield = 7.1%
Explanation:
The general reaction of the problem is:
Ca(OH)₂ + CO₂ → H₂O + CaCO₃
To solve this question we need to find theoretical yield using the amount of carbon dioxide added because:
Percent yield = Actual yield (3.22g) / Theoretical yield * 100
Theoretical yield is the maximum amount of product that could be obtained. To find it we need to convert the mass of CO₂ to moles. The moles of CO₂ = Moles of CaCO₃:
<em>Moles CO₂ -Molar mass: 44.01g/mol):</em>
20.0g * (1mol / 44.01g) = 0.454 moles CO₂ = Moles of CaCO₃ produced
<em>Mass CaCO₃ = Theoretical yield -Molar mass: 100.09g/mol-:</em>
0.454 moles * (100.09g / mol) = 45.5g of CaCO₃ = Theoretical yield.
Replacing:
Percent yield = 3.22g / 45.5g * 100
<h3>Percent yield = 7.1%</h3>
The answer is C 5m. Thanks
Answer:
either deposition or physical weathering
Answer:
Consequently, what happens when gas obtained by heating slaked lime and ammonium chloride is passed through copper sulphate solution? The HCl in the gas mixture will form hydrochloric and the H+ will react with some of the NH3(aq), forming NH4^+, and with some of the SO4^2-, forming HSO4^-.
