In this unit, we begin to name and write compounds and learn how to write out and balance chemical equations.
Chemists need to write out formulas and equations to solve chemistry problems. Example- CO2 Mass, C + O + O 12.011 + 15.994 + 15.994 43.999 Practice Compute the mass of the following compounds round to nearest tenth & state type of bond: NaCl 23 + 35 = 58 Ionic Bond C2H6 24 + 6 = 30 Covalent Bond Na(CO3)2 23 + 2(12 + 3x16) = 123 Ionic & Covalent electron shells Atomic number = number of Electrons Electrons vary in. Balancing chemical equation is the process of equalising the number of each element in the reactants to the products.įundamentals of Chemistry | Chemical Formulas & Composition Stoichiometry | Chemical Equations & Rxn Stoichiometry | Types of Chemical Reactions | | Atomic Structure | Chemical Periodicity | Chemical Bonding | Molecular Structure/Covalent Bonding Theories | Molecular Orbital Theory | The LHS consists of the reactants and the RHS consists of the products.
