For the phases of each compound, we have to put the appropriate symbol below as a subscript of the formula of the compound:
solid - (s)
liquid - (l)
gas - (g)
aqueous - (aq)
First, we take note of the list below for compounds that should be diatomic.
H N F O I Cl Br
Oxygen (O) belongs to this list so we know its diatomic.
Gaseous acetylene (C2H2) reacts with oxygen gas to form gaseous carbon dioxide and gaseous water. Express your answer as a chemical equation. Identify all of the phases in your answer.
Chlorine gas reacts with aqueous potassium iodide to form solid iodine and aqueous potassium chloride. Express your answer as a chemical equation. Identity all of the phases in your answer.
