Calculate the percent yield when 500 grams of carbon dioxide react with an excess of water to produce 640 grams of carbonic acid
Eddi Din [679]

Answer:

The answer to your question is 90.8%

Explanation:

Balanced Reaction

                         CO₂  +   H₂O   ⇒    H₂CO₃

Process

1.- Calculate the theoretical production of H₂CO₃

Molecular mass of CO₂ = 12 + 32 = 44 g

Molecular mass of H₂CO₃ = 2 + 12 + 48 = 62 g                          

                          44 g of CO₂  ----------------  62 g of H₂CO₃

                        500 g of CO₂ ---------------    x

                           x = (500 x 62) / 44

                           x = 704.54 moles of H₂CO₃

2.- Calculate the percent yield

Formula

Percent yield = \frac{experimental amount}{theoretical amount} x 100

Substitution

Percent yield = \frac{640}{704.54} x 100

Result = 90.8 %

What are the products of cyclic electron flow during the light reactions of photosynthesis?
Lynna [10]

Answer:

Cyclic electron flow uses just PS I and creates ATP.

Explanation:

Photo-system is known as light-absorbing complexes which are present on the thylakoid membrane of the photosynthetic organisms. A molecule called P700 which is present on PS l and absorb light of approximately 700 nm.

Cyclic electron flow has excited electrons from the photochemical reaction center (P700) in Photo-system I that is passed from Ferrodoxin to the cytochrome complex and back to the photochemical reaction center. Cyclic electron flow only uses PS I and produces ATP, not O2 or NADPH.

Compared with the energy it takes to separate oxygen and hydrogen from water. How much energy is released when they recombine?.
Stolb23 [73]

The same amount of energy is released when they recombine.

<h3>How to separate oxygen and hydrogen from water?</h3>
  • Electrolysis is a promising choice for without carbon hydrogen creation from inexhaustible and atomic assets.
  • Electrolysis is the method involved with utilizing power to part water into hydrogen and oxygen.
  • This response happens in a unit called an electrolyzer.
  • Electrolyzers can go in size from little, apparatus size hardware that is appropriate for limited scope dispersed hydrogen creation to huge scope, focal creation offices that could be tied straightforwardly to sustainable or other non-ozone depleting substance radiating types of power creation.
<h3>How Does it Work?</h3>

Like energy components, electrolyzers comprise of an anode and a cathode isolated by an electrolyte. Different electrolyzers capability in various ways, fundamentally because of the different kind of electrolyte material included and the ionic species it conducts.
