Diffusion is the flow of a compound from an area of higher to lower concentration. In a cell water freely diffuses in and out of the cell dependent on the concentration of solutes while larger charged ions and other chemicals have specific channels and carriers. Changing concentration is a chemical change.

How does a chemical equation show that a chemical reaction has occurred?
A chemical equation shows that chemical reaction has occurred as new substances have been formed from the reagents. A chemical equation has two sides before reaction and after reaction, if there is any change from the before reaction side to the after reaction side, it indicates that a chemical reaction has just occurred.
Is flammability a physical property or a chemical property?
chemical property.Flammability is a chemical property (reaction with oxygen=oxydation).
Which action forms a different chemical substance?
Any chemical reaction produce a new substance.
What are the two attributes of a catalyst?
A catalyst must change the rate of a chemical reaction. It must be unchanged at the end of the reaction.
What is the speed at which a reaction occurs called?
The chemical term is reaction rate.
Is rust diffusion?
In chemistry diffusion is the passage of particles across a membrane. Diffusion does not relate to the rusting of iron (Fe). Rust itself is an oxidation reaction, rather than diffusion. Oxidation involves the chemical reaction of Fe to atmospheric oxygen (O) to form iron oxides (FeO)s.
Are substances broken down during the diffusion process?
Diffusion refers to the moving of a solute from an area of high concentration to an area of low concentration. No chemical reactions take place BECAUSE of diffusion. It is possible that something could be diffusing WHILE undergoing a chemical reaction, but the processes would be unrelated.
Is diffusion a chemical reaction or a change of state?
Diffusion is a change of state. A good example of diffusion is when you can smell something cooking that is in another room. Moisture in the food evaaporates and the gas formed is diffused and you can smell it. I'm not sure that I'm right but i learnt about diffusion in science recently ;-)
Is fertilizer chemical or physical reaction?
Fertilizer typically involves a chemical reaction when applied to soil. The components in the fertilizer interact with the soil and plants to provide essential nutrients for growth. Physical processes such as dissolving and diffusion also play a role in the uptake of nutrients by plants.
How Keq affect diffusion?
The equilibrium constant (Keq) reflects the ratio of concentrations of products to reactants at equilibrium in a chemical reaction. While Keq itself does not directly affect diffusion, it influences the concentration gradients that drive diffusion. When a reaction reaches equilibrium, the concentrations stabilize, impacting the net movement of molecules. Thus, changes in Keq can indirectly affect the diffusion rates by altering the concentration differences across a membrane or barrier.
When two gases are mixed what is it called?
When two gases are mixed together, it is referred to as a gas mixture. This is because the gases are physically combined, retaining their individual properties without a chemical reaction taking place.
What is a chemical change also referred to as?
Chemical reaction
What has the author A Fasano written?
A. Fasano has written: 'Problems in Nonlinear Diffusion' -- subject- s -: Diffusion processes, Reaction-diffusion equations, Congresses
How does an engine have a chemical reaction?
Combustion is a chemical reaction.
Is chemical reaction alive?
No. A chemical reaction is not alive.
What is the relation between reaction time and radius of the unreacted core when chemical reaction controls?
When a chemical reaction controls the rate of reaction, the reaction time is often inversely related to the radius of the unreacted core. As the radius increases, the volume of unreacted material grows, leading to longer diffusion paths for reactants to reach the core. Consequently, larger unreacted cores result in slower overall reaction rates and longer reaction times. This relationship is critical in understanding reaction kinetics, particularly in heterogeneous reactions involving solid reactants.
What chemical is formed in a chemical reaction?
A new chemical substance is formed during a chemical reaction by rearranging the atoms of the reactants. The products of a chemical reaction have different properties compared to the original reactants.
