Foundation reading 10 of 17 · ~4 min
Read physical-state symbols
Your goal: Recognize solid, liquid, gas and aqueous labels in a reaction.
A focused reading from Balancing Chemical Equations. Reading time is a Chem Help estimate.
Optional prerequisite review
Review if useful. These suggestions never lock a step.
State symbols
(s), (l), (g) and (aq) describe the physical state under the stated conditions. They do not affect atom balancing, but they carry chemical information, especially for precipitation and gas-forming reactions later in the course. Include them when the question supplies them.
