The Nernst equation allows us to predict the cell potential for voltaic cells under conditions other than the standard conditions of 1M, 1 atm, 25°C. The effects of different temperatures and concentrations may be tracked in terms of the Gibbs energy change ΔG. This free energy change depends upon the temperature & concentrations according to   ΔG = ΔG°  +  RTInQ  where ΔG° is the free energy change under conditions and Q is the thermodynamic reaction quotient. The free energy change is related to the cell potential  Ecell by ΔG= nFEcell

so for non-standard conditions
              -nFEcell = -nFE°cell  + RT InQ

or
   
              Ecell  =  E°cell - RT/nF (InQ) 

which is called Nernst equation.

C6H12O6 + 6O2 + 38ADP + 38Pi => 6CO2 + 6H2O + 38ATP is the chemical equation for
Jobisdone [24]

Answer:

C6H12O6 + 6O2 + 38ADP + 38Pi => 6CO2 + 6H2O + 38ATP is the chemical equation for cellular respiration

Explanation:

Cellular respiration is the process by which cells breakdown glucose molecules to produce energy in the form of ATP molecules and release waste products such as carbon dioxide and water molecules. Cellular respiration involves a series of reaction pathways such as glycolysis, pyruvate oxidation, citric acid cycle and the oxidative phosphorylation pathway.

The first step of glycolysis breaks down a glucose molecule to release two pyruvate molecules.

In pyruvate oxidation, two molecules of pyruvate are oxidized to acetyl-CoA molecules.

In the citric acid cycle, the acetyl-CoA molecules are used to produce the electron carriers NADH and FADH2.

In the oxidative phosphorylation pathway, NADH and FADH2 donate their electrons to oxygen and ATP molecules are produced using the energy of electron transfer and proton-pumping.

The overall equation for cellular respiration is given as:

C6H12O6 + 6O2 + 38ADP + 38Pi => 6CO2 + 6H2O + 38ATP

How many moles are in 442.8 g of strontium carbonate (SrCO3)?
GuDViN [60]

Answer:

3 moles

Explanation:

SrCO3

Mass = 442.8g

Molar mass = (87.6 + 12 * [16*3]) = 147.6g/mol

Number of moles = mass / molar mass

Number of moles = 442.8 / 147.6

Number of moles = 3

Write the difference between isomerism and allotropy with one example each.
fredd [130]

Answer:

hope it helps ..

Explanation:

Allotropes can be defined as different types of compounds made out of the same single element but in different chemical formulas and different arrangements. Isomers can be defined as the chemical compounds that have a similar molecular formula but with different structural formulae. Graphite and Diamond.
