• Balancing Ionic Equation: Mole Course (13)

  

  The ionic equation simplifies chemical reactions by omitting spectator ions, focusing solely on reacting ions.

• Balancing Chemical Equation: Mole Course (12)

  

  Balancing chemical equations involves ensuring an equal number of atoms on both sides, accounting for the transformation of reactants into products through bond breaking and formation.

• Calculating Formal Charge of Polyatomic Ions: Mole Course (11)

  

  Formal charge in compound ions is calculated by subtracting unshared electrons and half of shared electrons from valence electrons.

• Ionic Compounds: Moles course (10)

  

  An ionic compound is a chemical compound formed by the electrostatic attraction between positively charged ions (cations) and negatively charged ions (anions). Ionic compounds typically consist of metal cations and nonmetal anions, and they are held together by ionic bonds.

• The Molecular and Empirical Formulas: Moles course (9)

  

  The molecular formula is a formula that defines both the type and number of atoms in a compound. We use molecular formulas for writing balanced equations and calculating molar masses.

• Percentage composition by mass: Moles course (8)

  

  Percent composition by mass, also known as mass percent or w/w%, refers to the relative amount of each element present in a compound expressed as a percentage of its total mass.

• Significant figures: Moles Course (7)

  

  The number 0.042 has two significant figures (4 and 2), and it has two leading zeros. Whereas, 0.420 has three significant figures (4, 2, and 0), with one leading zero and one trailing zero.

• The Stoichiometry of A Reaction (Moles Course: 6)

  

  The stoichiometry of a reaction defines the precise quantitative relationship between the reactants and products, calculated through the balanced chemical equation.

• How to Calculate The Mass of A Substance (Moles Course: 5)

  

  The stoichiometry of a chemical reaction describes how much reactants and products are present in moles.

• The Mole and Avogadro’s Constant (Moles Course: 4)

  

  You will learn how to calculate moles, understand the importance of the Avogadro constant, and find the number of atoms in given substance quantities.

• How to Obtain Accurate Relative Atomic Mass? (Moles Course: 3)

  

  Accurate relative atomic mass can be obtained through the use of a mass spectrometer that measures the mass and abundance of isotopes within an element. The data generated by the mass spectrometer is then used to calculate the average atomic masses of all isotopes.

• Masses of Atoms and Molecules (Moles Cours: 2)

  

  Relative atomic mass is the average mass of an atom of an element, compared to 1/12th the mass of a carbon-12 atom. Relative molecular mass is the sum of the relative atomic masses of the atoms in a molecule.
