Question

identify the information that can be included in a chemical equation. check all of the boxes that apply.
□ how long the reaction takes to occur
□ the states of the reactants and products
□ the temperature and pressure at which the reaction was carried out
□ the relative amounts of reactants and products
□ the actual mass of product that is produced by the reaction
□ the type of catalyst that is used to speed up the reaction
□ the possibility that the reaction can go in both directions
done

Explanation:

• "how long the reaction takes to occur": Chemical equations don't show reaction time.
• "the states of the reactants and products": Can be included (e.g., (s), (l), (g), (aq)).
• "the temperature and pressure at which the reaction was carried out": Can be noted (e.g., Δ for heat, pressure symbols).
• "the relative amounts of reactants and products": Shown by coefficients.
• "the actual mass of product that is produced by the reaction": Chemical equations show relative, not actual mass.
• "the type of catalyst that is used to speed up the reaction": Can be written above/below the arrow.
• "the possibility that the reaction can go in both directions": Shown by a double arrow for reversible reactions.

Answer:

• the states of the reactants and products
• the temperature and pressure at which the reaction was carried out
• the relative amounts of reactants and products
• the type of catalyst that is used to speed up the reaction
• the possibility that the reaction can go in both directions
