unit 6 - writing and balancing chemical equations
... In chemistry, we use symbols to represent the various chemicals. Success in chemistry depends upon developing a strong familiarity with these basic symbols. A chemical equation is an expression of a chemical process. For example: AgNO3(aq) + NaCl(aq) AgCl(s) + NaNO3(aq) In this equation, AgNO3 is ...
