What is deltaHc?

Enthalpy change of combustion definition. The enthalpy change that occurs when one mole of a compound is completely combusted in excess oxygen under standard conditions. e.g. methane deltaHc. CH4(g) + O2(g) -> CO2 (g) + 2H2O (l) deltaHc= -891.

What’s the difference between Delta HF and Delta HC?

delta Hf is (-1000) delta Hc is (+1000) Please confirm or correct me, thanks! For the most part, and for the DAT, the heat of formation can be assumed to be negative and the heat of combustion is also negative. some heat of formations can be positive or neutral.

What’s the difference between Delta 8 and Delta 9 THC?

And with huge advances in Hemp science, scientists have figured out how to concentrate the Delta 8-THC content in Hemp while at the same time minimize the Delta 9-THC content to under the legal limit. This leaves us with a Hemp extract oil that is anywhere from 90%-98% pure Delta 8-THC, while keeping the Delta 9-THC percentage at essentially 0%.
