What is the strongest IMF for SeO2?

Joe Ford

What is the strongest IMF for SeO2?

(b) SeO2 has stronger intermolecular forces than SO2. Both SO2 and SeO2 have dipoles due to the bent shape of the molecules, but the bonds between oxygen and selenium are more polar than the bonds of SO2 because selenium is less electronegative than sulfur is.

What is the oxidation number of Cl in NOCl?

So, the oxidation number of N and Cl in NOClO4 are +3 and +7 respectively.

What is the oxidation number of S in H2SO5?

+6

How do you balance MnO4 C2O4?

The balanced half-reaction now becomes MnO4(-) + 8 H(+) + 5 e → Mn(2+) + 4 H2O, where e represents an electron. The oxidation half-reaction similarly becomes C2O4(2-) – 2e → 2 CO2. Balance the overall reaction by ensuring that the number of electrons in the oxidation and reduction half-reactions are equal.

Are all oxidation reactions redox?

An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron. Redox reactions are common and vital to some of the basic functions of life, including photosynthesis, respiration, combustion, and corrosion or rusting.

Is photosynthesis a redox reaction?

Photosynthesis is light-driven redox chemistry. Molecular redox signalling, the coupling of gene expression to electron transfer, is now implicated in the adaptation of photosynthesis to variation in light quality and quantity.

What are some common redox reactions?

The five main types of redox reactions are combination, decomposition, displacement, combustion, and disproportionation.

What happens during carbon fixation?

Carbon fixation is the process by which inorganic carbon is added to an organic molecule. Three molecules of CO2 along with ATP, NADPH, and water are needed for a full turn of the cycle and the production of a glyceraldehyde 3-phosphate (Ga-3P) molecule for use by the cell in making starch or sugar.

What is the final product of the Calvin cycle?

glucose

Is carbon fixation the same as Calvin cycle?

The Calvin cycle uses the energy from short-lived electronically excited carriers to convert carbon dioxide and water into organic compounds that can be used by the organism (and by animals that feed on it). This set of reactions is also called carbon fixation.

What are the 3 products of the light reaction?

Light reactions harness energy from the sun to produce chemical bonds, ATP, and NADPH. These energy-carrying molecules are made in the stroma where carbon fixation takes place. The light-independent reactions of the Calvin cycle can be organized into three basic stages: fixation, reduction, and regeneration.

Where does light reaction occur?

The light reaction takes place in the thylakoid discs. There, water (H20) is oxidized, and oxygen (O2) is released. The electrons freed up from water are transfered to ATP and NADPH. The dark reaction occurs outside of the thylakoids.

What are the 4 steps of light reactions?

Here are the basic steps:

  • Light absorption in PSII. When light is absorbed by one of the many pigments in photosystem II, energy is passed inward from pigment to pigment until it reaches the reaction center.
  • ATP synthesis.
  • Light absorption in PSI.
  • NADPH formation.

What are the 3 phases of Calvin cycle?

The Calvin cycle reactions can be divided into three main stages: carbon fixation, reduction, and regeneration of the starting molecule.

Why is it called C3 cycle?

The carbon and oxygen required for this process are obtained from CO2, and the energy for carbon fixation is derived from the ATP and NADPH produced during the photosynthesis process. The conversion of CO2 to carbohydrate is called Calvin Cycle or C3 cycle and is named after Melvin Calvin who discovered it.

Why is the Calvin cycle called a cycle?

The cycle is light-independent because it takes place after the energy has been captured from sunlight. The Calvin cycle is named after Melvin C. Calvin, who won a Nobel Prize in Chemistry for finding it in 1961.
