Water, H2O, has a higher boiling point than methane, CH4. TRUE FALSE

determine the percent yield for carbon dioxide if 4.50 moles of propane yielded 7.64 moles of carbon dioxide

ira [324]

Answer:

Percent yield = 57%

Explanation:

Given data:

Number of moles of propane = 4.50 mol

Number of moles of carbon dioxide = 7.64 mol

Percent yield = ?

Solution:

Chemical equation:

C₃H₈ + 5O₂ → 3CO₂ + 4H₂O

Now we will compare the moles of propane and carbon dioxide.

C₃H₈ : CO₂

1 ; 3

4.50 : 3×4.50 = 13.5 mol

Percent yield:

Percent yield = actual yield / theoretical yield × 100

Percent yield = 7.64 mol / 13.5 mol × 100

Percent yield = 0.57× 100

Percent yield = 57%

How many moles of AgNO3 must react to form 0. 854 mol Ag? mol AgNO3.

babunello [35]

The moles of silver nitrate required to form 0.854 mol silver ion has been 0.854 mol.

The balanced chemical equation for the dissolution of silver nitrate has been:

$\rm AgNO_3\;\rightarrow\;Ag^+\;+\;NO_3^-$

The aqueous solution of silver nitrate has been dissociated into the constituent silver and nitrate ions.

In a balanced chemical equation, the coefficient has been equivalent to the moles of each reactant forming the moles of product.

From, the balanced equation,

$\rm 1\;mol\;AgNO_3=1\;mol\;Ag$

The given moles of Silver has been 0.854 mol. Thus, the moles of silver nitrate required has been given as:

$\rm 1\;mol\;Ag^+=1\;mol\;AgNO_3\\0.854\;mol\;Ag^+=0.854\;\times\;1\;mol\;AgNO_3\\0.854\;mol\;Ag^+=0.854\;mol\;AgNO_3$

The moles of silver nitrate required to form 0.854 mol silver ion has been 0.854 mol.
