“produces.” Chemical Equations (2)
• The physical states of the reactants
and products are provided in the
equation.
– A (g) following a formula tells us the
substance is a gas. Solids are
described with (s). Liquids are
described with (l). When a substance
is dissolved in water, it is described
with (aq) for “aqueous,” which means
“mixed with water.” Chemical Equations (3)
• The relative numbers of particles of
each reactant and product are
indicated by numbers placed in front
of the formulas.
– These numbers are called coefficients. An
equation containing correct coefficients is
called a balanced equation.
– If a formula in a balanced equation has no
stated coefficient, its coefficient is understood
to be 1. Chemical Equations (4)
• If special conditions are
necessary for a reaction to tak...
