A substance that shows a decrease in oxidation number during chemical reaction?
A substance that shows a decrease in oxidation number during a chemical reaction is being reduced. Reduction involves a decrease in the oxidation number of an element. This indicates a gain of electrons by the substance.
How can you tell which substance gets oxidized and which gets reduced in a chemical reaction?
You simply look at the ions. Here, let me explain:2Cl- (l) --> Cl2(g) + 2e- would be an example of oxidation since electrons are being lost.Ca2+ (l) + 2e- --> Ca(s) would be an example of reduction since electrons are being gained.Here's one helpful mnemonic for remembering this:LEO- lose electrons oxidationGER- gain electrons reduction"LEO the lion says GER."Hope this helps! ^_^
Is photosynthesis in leaves a chemical or physical change?
Photosynthesis is a chemical reaction. Using Sunlight, water, and carbon dioxide, plants can produce high energy sugars and oxygen. Here is the formula:Sunlight + 6H2O + 6CO2 ----> C6H12O6, 6O2
What does the term reduced mean in a chemical reaction?
In a chemical reaction, the term "reduced" refers to a substance gaining electrons or decreasing its oxidation state. This results in a decrease in the number of positive charges on the atom or molecule. Reduced substances are often involved in redox reactions where they act as electron acceptors.
A substance that can not be reduced to a simpler substance by chemical means?
An "element"
When chalk is crushed is it a physical or chemical property?
Crushing chalk is a physical change, not a chemical change. Physical changes alter the form or appearance of a substance without changing its chemical composition. So, when chalk is crushed, it remains the same substance chemically but in a smaller form.

What is the relationship between oxidising agent and the reduced substance?
Its the substance reduced which is termed to be an oxidizing agent. When a substance is reduced, it loses electrons that are taken up by another substance thereby oxidizing another substance (oxidising agent).

Is photosynthesis is chemical or physical change?
ChemicalCO2 is reduced into glucose. Water is oxidized into Oxygen.Also energy transformation occurs. Light energy transforms into chemical energy
When a substances gains electrons is it reduced?
Yes when any substance gains electrons , that substance is now then reduced.
Is electroplating physical or chemical change?
Electroplating involves a combination of physical and chemical changes. The metal ions (chemical change) in the solution are reduced and deposited onto the object's surface using electricity (physical process).
What is the degree of reduction for the chemical reaction taking place in this experiment?
The degree of reduction for a chemical reaction is the number of electrons gained by the atoms of a substance. It indicates how much the atoms have been reduced in terms of their oxidation state.
