Chemical Equations

Use the standardized names and symbols of common elements and compounds to write accurate chemical formulae and fully balanced chemical equations.

Write and balance chemical half-equations.

Use chemical symbols to construct the distinct formulae of base elements, simple covalent compounds, and ionic compounds.

Differentiate between the three states of matter in chemical equations using appropriate state symbols and represent aqueous solutions appropriately.

Recognize that atoms of each specific element are represented by a unique chemical symbol.

Understand that compounds are formed exclusively from elements undergoing chemical reactions, combining in fixed proportions, and represent them using symbols.

Recall that compounds can only be separated back into individual elements through further chemical reactions.

Describe how chemical reactions always result in the formation of new substances and frequently involve a detectable change in energy.

Construct accurate word equations for all specific chemical reactions outlined in the specification.

Use a supplied periodic table to identify the names and symbols of the first 20 elements, elements in Groups 1, 7, and 0, and construct appropriate equations.
