What does a delta symbol mean in a reaction?
The delta symbol in a chemical equation stands for "change". Since you have to break and reform the bonds between atoms in molecules to have a chemical reaction there is going to be a change, whether it be in the thermal energy, chemical energy, phase of the matter etc.
Why is triangle symbol used in chemical reaction?
A triangle symbol in a chemical reaction formula means that there is heat supplied to the reaction. The triangle is typically placed above the arrow between reactants and products. Sometimes the word "heat" is also written above the arrow.
How to calculate the heat of reaction in a chemical reaction?
To calculate the heat of reaction in a chemical reaction, you can use the formula: H (Hf products) - (Hf reactants), where H is the heat of reaction, Hf is the standard heat of formation, and the symbol means to sum up the values for all products and reactants. This formula helps determine the amount of heat released or absorbed during a chemical reaction.
