4fe₂o₃
4fe₂o₃
\yields\ or \produces\

eacts with\
used to represent \aqueous\ or \solutions\
used to represent \solids\
used to represent \gaseous\
used for liquid water or molten metals (any liquids not aqueous)
chemical formula (s) → (g) + (aq) coefficients () subscripts

Explanation:

Step1: Analyze "4Fe₂O₃" (coefficient)

The number 4 in front of \( \text{Fe}_2\text{O}_3 \) is a coefficient, so match "4Fe₂O₃" (with 4 as coefficient) to "coefficients".

Step2: Analyze "Fe₂O₃" subscripts

The numbers 2 and 3 in \( \text{Fe}_2\text{O}_3 \) are subscripts, so match the part with subscripts (like the circled 2 and 3) to "subscripts".

Step3: Analyze "Fe₂O₃" (chemical formula)

\( \text{Fe}_2\text{O}_3 \) is a chemical formula, so match the boxed \( \text{Fe}_2\text{O}_3 \) to "chemical formula".

Step4: Analyze "yields"

"yields" or "produces" is represented by \(
ightarrow \), so match to "→".

Step5: Analyze "reacts with"

"reacts with" is represented by \( + \), so match to "+".

Step6: Analyze "aqueous"

"Aqueous" is represented by (aq), so match "used to represent 'aqueous' or'solutions'" to "(aq)".

Step7: Analyze "solids"

"Solids" are represented by (s), so match "used to represent'solids'" to "(s)".

Step8: Analyze "gaseous"

"Gaseous" is represented by (g), so match "used to represent 'gaseous'" to "(g)".

Step9: Analyze "liquid water/molten"

Liquid water or molten metals (non - aqueous liquids) are represented by (l), so match "used for liquid water OR molten metals (any liquids not aqueous)" to "(l)".

Answer:

• \( \boldsymbol{4}\text{Fe}_2\text{O}_3 \) → coefficients
• \( 4\text{Fe}_{\boldsymbol{2}}\text{O}_{\boldsymbol{3}} \) → subscripts
• \( 4\boldsymbol{\text{Fe}_2\text{O}_3} \) → chemical formula
• "yields" or "produces" → \(

ightarrow \)

• "reacts with" → \( + \)
• used to represent "aqueous" or "solutions" → (aq)
• used to represent "solids" → (s)
• used to represent "gaseous" → (g)
• used for liquid water OR molten metals (any liquids not aqueous) → (l)
