Electric potential energy
... The term “high voltage” means that there is a “high potential (high likelihood)” that electricity will move from a high to a low potential. Potential by itself cannot harm you. It is a measure of the pressure on the charges and the likelihood that charges will move from an object labeled “high volta ...

Describing Chemical Reactions
... balance a chemical equation, you may have to use coefficients. A coefficient is a number placed in front of a chemical formula in an equation. It tells you how many atoms or molecules of a reactant or a product take part in the reaction. Many chemical reactions can be classified in one of three cate ...

How do we predict chemical change?
... Not every combination of substances will lead to the formation of new compounds via a chemical reaction. How can we predict when a chemical process takes place? One approach could be to compare the relative stability of reactants and products. We might expect that chemical reactions will proceed in ...
