Significance of delta sign

Postby 104730551 » Sun Jul 02, 2017 12:28 pm

In a chemical equation, we know a delta sign indicates that the reaction is heated. How might this impact the problem overall?

In Chem 14A it does not have much significance in problem solving.

In thermodynamics (Chem 14B) it would be informative.

The significance of a delta sign is to show that a reaction is heated or that it is a combustion reaction. I think it's also important to mention that in a combustion reaction, it's common to have oxygen gas (O2) as a reactant and the products of carbon dioxide (CO2) and water (H2O). During discussion my TA told me that the delta on top of the reaction arrow isn't essential in chem14A, but will be in future chemistry classes like organic chemistry :)
