“This shift from kelp to turf is analogous to a terrestrial forest transitioning into a grassland,” said the study’s lead ...

Researchers at the University of Sydney have successfully performed a quantum simulation of chemical dynamics with real ...

Instead, the atoms rearrange themselves to form new chemicals. This is known as a chemical change. The other kind of change in chemistry is a physical change, which is when a substance changes ...

The speed of a chemical reaction is affected by temperature, concentration, particle size and the presence of a catalyst. It can be calculated by measuring changes in reactants/products.

The lesson can also be used to lay a foundation for learning about changes in state and chemical changes which can be further developed in later grades. If water is cooled enough it can change to ice.

Both chemical changes generating electric currents and chemical reactions triggered by the passage of electricity can be considered electrochemical reactions. Hypochlorite is in wide industrial ...

Students explore the concept that chemical reactions involve the breaking of bonds between atoms in the reactants, and the rearrangement and rebonding of these atoms to make the products. Students ...

Every autumn we revel in the beauty of the fall colors. The mixture of red, purple, orange and yellow is the result of chemical processes that take place in the tree as the seasons change from summer ...
