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 chemical reaction takes place when bleaching a stain?
This action involve a chemical reaction.
When chemical X is reduced which of these expressions would be an accurate representation of its reduced state?
XH
The substance that accepts electrons from another substance is the?
In a redox reaction, the substance that accepts electrons is said to be the substance reduced. This substance is also likely the oxidizing agent, since oxidation is the loss of electrons.
What substance is transported as reduced hemoglobin in the blood?
Hydrogen Ion :-)
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?
I would say it is a physical change the chalk is being reduced to a smaller size. It still remains chalk.
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).
What chemical reaction takes place when bleaching a stain?
This action involve a chemical reaction.
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.
What is a reduced compound?
A reduced compound is a compound that came into contact with another chemical, experienced a chemical reaction, and lost an electron in the reaction. Reduced compounds are often oxidized.
What chemical change occurs when more reactive substance replaces a less reactive substance in a compound?
reduction or oxidation example: (this isn't a real reaction) ClO + CS4 --> CO + ClS4 the chorine has been reduced, because the carbon is more reactive the carbon has been oxidised, because it is more reactive oxidation = the addition of oxygen reduction = the subtraction of oxygen
What is meaning of word element in dictionary?
A substance composed of atoms having an identical number of protons in each nucleus. Elements cannot be reduced to simpler substances by normal chemical means.
When chemical X is reduced which of these expressions would be an accurate representation of its reduced state?
XH
Why a substance that oxidised is called a reducing agent and why a substance that is reduced is called an oxidising agent?
It is because when a substance is oxidized, it loses electrons which are taken up by other so that is gets reduced.This is why it is called reducing agent. Similarly, the substance reduced is called oxidizing agent.
