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.
In the chemical reaction that takes place in the lighting of a match activation energy is supplied by?
The activation energy in the chemical reaction of lighting a match is supplied by the heat generated when the match is struck against the striking surface. This heat is enough to break the chemical bonds in the match head, leading to combustion and the release of energy in the form of light and heat.
What is the bomb calorimetry formula used to calculate the heat released during a chemical reaction?
The bomb calorimetry formula used to calculate the heat released during a chemical reaction is Q mcT, where Q is the heat released, m is the mass of the substance, c is the specific heat capacity, and T is the change in temperature.
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.
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.

What is the small triangle above the horizontal arrow in a chemical equation?
It means heat was supplied to make the reaction occur.

The bomb calorimetry formula used to calculate the heat released during a chemical reaction is Q mcT, where Q is the heat released, m is the mass of the substance, c is the specific heat capacity, and T is the change in temperature.
What is the chemical formula of a exothermic reaction?
Impossible to answer. Exothermic reaction is just one of the two possible chemical reactions: either exothermic or endothermic. (No difference but heat release)
What is the relationship between the heat of reaction and the chemical reaction?
The heat of reaction is the amount of heat released or absorbed during a chemical reaction. It is a measure of the energy change that occurs as reactants are converted into products. The relationship between the heat of reaction and the chemical reaction is that the heat of reaction indicates whether a reaction is exothermic (releases heat) or endothermic (absorbs heat).
What is a heat reaction?
This the heat released during a chemical 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.
Is endothermic a chemical reaction?
Yes. A chemical reaction which absorbs heat during the reaction. The opposite to exothermic which releases heat during the reaction.
What is the relationship between the heat of reaction and a chemical reaction?
The heat of reaction is the amount of heat energy released or absorbed during a chemical reaction. It is a measure of the reaction's energy change. The relationship between the heat of reaction and a chemical reaction is that the heat of reaction indicates whether a reaction is exothermic (releases heat) or endothermic (absorbs heat). This information helps us understand the energy changes that occur during the reaction.
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.
A chemical reaction that gives off heat is most likely to be what?
An endothermic reaction is one that consumes heat.
