For instance, breathable oxygen gas O2 is an example of a molecule (but, not a compound), while carbon dioxide CO2, the gas we exhale, is an example of a molecule that is a compound.Answer and Explanation: A substance is a material that has constant or uniform chemical and physical comp...
In a chemistry class, the teacher is teaching students about chemical substances and their properties. Today, the focus is on two important substances: substance A and substance B.Substance A has a melting point of 80°C and a boiling point of 210°C. It is a color - less liquid at roo...

1 请教一句关于as a result of which的从句 原句:We may define chemistry as the science in which we deal with the chemical change in matter as a result of which it is possible to form a new substance. 句子的意思我能明白:我们可以说,化学是论述物质化学变化的科学,通过化学变化可能形成新的物质....
In chemistry, a mole is a quantity used relate reactants to products in stoichiometric equations. A mole of any substance is equal to 6.02 x 10^23 particles -- usually atoms or molecules -- of that substance. For a given element, the mass (in grams) of o
colligative property, in chemistry, any property of a substance that depends on, or varies according to, the number of particles (molecules or atoms) present
Concentration in chemistry is the amount of substance in a specific volume or space. There are different ways to calculate concentration, like molarity, mass concentration, and volume percent. Concentrated solutions have lots of solute, while dilute solutions have more solvent and less solute. ...
