what colour change occurs during the calcium and hydrochloric acid reaction
A catalyst undergoes no chemical change during a chemical reaction.
The enthalpy of a chemical reaction is the change of heat during this reaction.
The enthalpy of a chemical reaction is the change of heat during this reaction.
Bruxism
A gas released during a chemical reaction is a chemical change.
To calculate the change in enthalpy during a chemical reaction, subtract the sum of the enthalpies of the reactants from the sum of the enthalpies of the products. This difference represents the change in enthalpy for the reaction.
During an exothermic reaction, the temperature increases because heat is released as a byproduct of the reaction.
The enthalpy of a chemical reaction is the change of heat during this reaction.
The enthalpy of a chemical reaction is the change of heat during this reaction.
