Julli [10]

When energy depleted elements associated with a proton are accepted by an organic molecule the process is called Fermentation.

Fermentation is a metabolic process that causes a chemical change inside body by the actions of enzymes.

The main purpose of fermentation is to generate NAD+ and 32 ATP in the presence of oxygen.

Fermentation allows cells to survive without using ATP.

If you obtained 2.50 moles of CuSO4 from the reaction of CuO and H2SO4, but the theoretical yield was 3.19 moles, what was the p
IceJOKER [234]

Answer:

  • 78.4%

Explanation:

Just as context, write the chemical equation and the mole ratios

1) <u>Balanced chemical equation</u>:

  • CuO (s) +  H₂SO₄ (aq) → CuSO₄ (aq) + H₂O (l)

2) <u>Therotetical (stoichiometric) mole ratios</u>:

  • 1 mol CuO : 1 mol  H₂SO₄  : 1 mol CuSO₄  : 1 mol H₂O

You can calculate the percent yield from the amount of CuSO₄ obtained and the theoretical yield

3) <u>Percent yield</u>

  • Definition:

         Percent yield = (actual yield / theoretical yield)×100

  • Theoretical yiedl (given): 3.19 moles CuSO₄

  • Actual yield (given): 2.50 moles CuSO₄

  • Calcualtion:

Substitute the values in the formula:

  • Percent yield = (2.50 moles CuSO₄ / 3.19 moles CuSO₄)×100 = 78.4%

Given : Density of Bromine = 3.12 g/mL
Formula : Density = Mass / Volume

Part A :
Given Volume = 125 mL
Density = Mass / Volume
So, Mass = Density x Volume
= 3.12 x 125
= 390 grams

Part B :
Given mass = 85.0 gm
Density = Mass / Volume
So, Volume = Mass / Density
= 85 / 3.12
= 27.24 mL
