This equation can be interpreted in two different ways: 1 molecule of methane and 2 molecules of oxygen produce 1 molecule of carbon dioxide and 2 molecules of water 1 mole of methane and 2 moles of oxygen produce 1 mole of carbon dioxide and 2 moles of water For the purposes of this ...
Whether a perfume fragrance comes from a flower or a lab, the molecules you smell and enjoy are an example of organic chemistry. The cosmetics industry is a lucrative sector of organic chemistry. Chemists examine changes in the skin in response to metabolic and environmental factors, formulate pr...
As much as a car is a single unit made up of many parts, a molecule is a unit made up of atoms bonded around each other in certain fixed geometries. Shapes influence the physical and chemical properties and consequently much of the chemistry of a molecule. While molecules may be mono...

The word cohesion comes from the Latin wordcohaerere, which means "to stick together or stay together." In chemistry, cohesion is a measure of how well molecules stick to each other or group together. It is caused by the cohesive attractive force between like molecules. Cohesion is an intrin...

In chemistry there are usually two types of changes that can take place: physical and chemical. Physical are those that are usually less difficult and can usually be undone easily, even if over time. Chemical change, however, takes place when the internal make-up or the molecules of the obj...

In chemistry and biology, a macromolecule is defined asa moleculewith a very large number of atoms. Macromolecules typically have more than 100 component atoms. Macromolecules exhibit very different properties from smaller molecules, including their subunits, when applicable. ...
