Methods of Balancing Chemical Equations
Balancing by inspection: Consider the example: We notice that there are 2 nitrogens on both the left and right sides, so nitrogen is already balanced.…

Law of Conservation of Energy
The law of conservation of energy is one of the basic laws of physics and therefore governs the microscopic motion of individual atoms in a…
Dalton’s Law of Partial Pressures
Key Concepts Partial pressure of a gas in a mixture of gases is the pressure which that gas would exert if it were the only…
What is Dalton’s Law?
Dalton’s Law: The pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases. Concepts One of…
What is The Law of Conservation of Mass?
The mass of the substances entering into a reaction equal the mass of the substances formed as a result of the reaction. (M.V. Lomonosov, 1748, A.…
What is Charles’s Law?
Charles’s Law: At constant pressure, the volume of a confined gas is directly proportional to the absolute temperature. V = kT Charles’s law is an…
What is Avogadro’s Law?
“Equal volumes of gases under identical temperature and pressure conditions will contain equal numbers of particles (atoms, ion, molecules, electrons, etc.)” Avogadro’s law is an…
Avogadro’s Law Example Problem
Question: Three balloons are filled with different amounts of an ideal gas. One balloon is filled with 3 moles of the ideal gas, filling the…
What is Atomic Mass Unit?
Atomic Mass Unit is defined as a mass exactly equal to one-twelve the mass of one carbon-12 atom. One atomic mass is also called one…
Explain Boyle’s Gas Law
“At constant temperature, the volume of a confined gas is inversely proportional to the pressure to which it is subjected”. (PV = k) The law…
