What else can I help you with?
Why can you not use an equals sign for a chemical equation?
An equals sign is not used in a chemical equation because it implies a mathematical equality, while a chemical equation represents a chemical reaction where atoms are rearranged to form new substances. Instead, chemical equations use an arrow to indicate the direction of the reaction.
When does heat equal enthalpy in a chemical reaction?
Heat equals enthalpy in a chemical reaction when the reaction is carried out at constant pressure.
When does the change in enthalpy equal heat in a chemical reaction?
The change in enthalpy equals the heat in a chemical reaction when the reaction occurs at constant pressure.
