What is an example of a reduction reaction performed by cells in which hydrogen is NOT to added to the reduced compound?
An example of a reduction reaction where hydrogen is not added to the reduced compound is the reduction of iron(III) to iron(II) by vitamin C. In this reaction, vitamin C acts as a reducing agent by donating electrons to iron(III) without the addition of hydrogen.
When organisms began using photosynthesis what gas was added to the atmosphere as a result?
Oxygen is one of the products of photosynthesis and is the gas that rose in abundance in the atmosphere due to the process of photosynthesis.
How do the two photosystems work together to capture energy from sunlight?
Photosystem 2 transports the electrons from water and oxygen and Hydrogen ions across the Thylakoid membrane. Photosystem 1 produces NADPH with the electrons being added to NADP. ADP is changed to ATP when the Hydrogen ions flow through ATP synthase. I hope this helps! :)
Why does the atomic radius change as electrons are added to a shell?
The atomic radius decreases as electrons are added to a shell because the increasing number of electrons increases the electrostatic force of attraction between the electrons and the nucleus, pulling the electrons closer to the nucleus and reducing the atomic radius.
Why do atoms get smaller when more electrons are added?
Adding more electrons to an atom results in increased electron-electron repulsion, which causes the electrons to be pulled closer to the nucleus to minimize this repulsion. As a result, the atomic radius decreases as more electrons are added.
In photosynthesis redox reactions ultimately transfer electrons from where?
§Photosynthesis, like respiration, is a redox (oxidation-reduction) process -Water molecules are split apart by oxidation, which means that they lose electrons along with hydrogen ions (H+) -Then CO2 is reduced to sugar as electrons and hydrogen ions are added to it This means that the electrons are moved from a water molecule to a carbon dioxide molecule. H2O >> CO2
Which element is added to NAD to reduce it?
Hydrogen ions and a pair of electrons are added to NAD+ to reduce it to NADH. This reduction reaction is important in cellular respiration for the generation of ATP.
What is the molecule that's split in the photosynthesis to provide electrons?
H20 is split into H2 and 02. The 02 (oxygen) leaves the plant through the stroma, and the H2 (hydrogen) goes through ATP synthase to become ADP and then another phosphate group is added for it to become ATP.
What is the equation that shows how nadp is changed into nadph?
NADP+ accepts and holds 2 high-energy electrons along with a hydrogen ion (H+).
What is the role of redox reaction in photosynthesis?
In photosynthesis, redox reactions play a crucial role in transferring electrons from water to carbon dioxide, converting them into oxygen and glucose. This electron transfer is essential for the production of energy in the form of ATP and NADPH, which are used in the synthesis of carbohydrates in plants.
How many electrons are needed to fill valence shell in hydrogen?
The atomic number for hydrogen (H) is 1 in the Periodic Table of Elements and it has that number of electrons (Valence & otherwise). Hence H2O for water since Oxygen O needs 2 electrons added to its valence electrons to make the stable compound WATER.
What is the source of oxygen gas given off during photosynthesis?
The Hydrogen ion is added to take the place of the energized electron in the light reaction of photosynthesis. The Hydrogen electron is taken from an H2O molecule. The oxygen is released as a waste product and the rest of the Hydrogen goes off to do work as energy is released.
What is an example of a reduction reaction performed by cells in which hydrogen is NOT to added to the reduced compound?
An example of a reduction reaction where hydrogen is not added to the reduced compound is the reduction of iron(III) to iron(II) by vitamin C. In this reaction, vitamin C acts as a reducing agent by donating electrons to iron(III) without the addition of hydrogen.
What happens when a metal is added to an acid?
When a metal is added to an acid, a chemical reaction can occur which results in the production of hydrogen gas and a salt specific to the metal and acid used. The metal atoms donate electrons to the hydrogen ions in the acid, leading to the formation of hydrogen gas bubbles. This reaction is a common way to test the reactivity of metals.
What is the definition for reduction in chemistry?
Reduction in chemistry refers to a chemical reaction in which a substance gains electrons, either by accepting hydrogen atoms or by losing oxygen atoms. This process results in a decrease in the oxidation state of the substance.
How can hydrogen be added to water?
Hydrogen can be added to water through a process called electrolysis, where an electric current is passed through water to separate it into hydrogen and oxygen gases.
What is the charge if you have more electrons?
the charge on an Ion is - if electrons have been added :)
