PPT-Chemical Formulas TEKS 8.5 D and 8.5 F

Recognize that chemical formulas are used to identify substances and determine the number of atoms of each element in chemical formulas containing subscripts Recognize whether a chemical equation containing coefficients is balanced or not and how that relates to the law of conservation of mass. Chemical Butyl Acetate Chemical Butylated Hydroxytoluene Chemical Coal ar Chemical Cocamide DEALauramide DEA Chemical Diazolidinyl Urea Chemical Ethyl Acetate Chemical Formaldehyde Chemical P Formulas. Chemical Formulas represent compounds.. Oxidation Numbers are used to determine the ratio in which elements combine to form compounds.. Understanding Chemical. Formulas.

This means that whatever elements go into a chemical equation (Reactants) must also come out of the chemical equation (Products).
