Chem: Lesson 6

It consists of symbols and formulas representing a chemical reaction.

• Chemical Equation

• Chemical Reaction

• Chemical Structure

• Chemical Balancing

In a chemical equation, the original species at the left side of arrow are called reactants and the species formed as a result of the reaction written at the right side of arrow called as products.

• True

• False

A process in which one set of chemicals is mixed and transformed into a new set of chemicals.

• Chemical Equation

• Chemical Reaction

• Chemical Structure

• Chemical Balancing

Written between the symbols and/or formulas of reactants or products

• (+)

• (--->) or (=)

• (⇌)

• (g)

Left side- read as "combine with" or "reacts with" right side- read as "and' or "plus"

• (+)

• (--->) or (=)

• (⇌)

• (g)

Means "yields" or "produce"; separates reactants from products.

• (+)

• (--->) or (=)

• (⇌)

• (g)

Use for reversible reactions in place of a single arrow.

• (+)

• (--->) or (=)

• (⇌)

• (g)

Indicates a gaseous reactant or product.

• (+)

• (--->) or (=)

• (⇌)

• (g)

Indicates a solid reactant or product.

• (s)

• (l)

• Delta above an arrow

• H2O above an arrow

Indicates a liquid reactant or product.

• (s)

• (l)

• Delta above an arrow

• H2O above an arrow
