# How to write a thermochemical equation

## What information does the thermochemical equation give?

Contents

AND thermochemical equation it consists of two parts: a balanced chemical equation and a change in one or more thermodynamic quantities (e.g., temperature, energy, or enthalpy) that occurs when the change occurs. Balanced equation can describe either a physical change (as in example shown) or chemical change.

## How to explain the thermochemical equation with an example?

Such equation which contains information about heat change is called a thermochemical equation. In this case, it is very important to indicate the physical condition of the different species involved. Examples is: (i) C (s) + O2 (g) → CO2 (g); AH = -393.5 kJ.

## What is a thermochemical equation, give two examples?

Explanation: Such an equation which contains information about heat change is called a thermochemical equation. In this case, the physical indication is very important country the different species involved. Examples is: (i) C (s) + O2 (g) → CO2 (g); AH = -393.5 kJ.

## What does a thermochemical reaction mean?

Thermochemistry is the study of energy and heat related to chemicals reactions and / or physical changes. AND reaction it can release or consume energy, and a phase change can do the same, for example during melting and boiling.

## What are the two types of thermochemical reactions?

Endothermic reactions they absorb heat, and are exothermic reactions release heat. Thermochemistry combines the concepts of thermodynamics with the concept of energy in the form of chemical bonds.

## What is a balanced thermochemical equation?

Thermochemical equations are balanced chemical equations which include the physical states of all reactants and products, and energy change. If energy is a reactant, the reaction is endothermic, but if energy is a product, the reaction is exothermic.

## What is an Enthalpy Graph?

some enthalpy graph shows information about a chemical reaction such as initial energy level, how much energy needs to be added to activate the reaction and final energy. some enthalpy graph is deleted from enthalpy on the y axis, and the time or reaction progress on the x axis.

## What does the exothermic equation look like?

General equation by exothermic the reaction is: Reagents → Products + Energy. If the energy produced in exothermic the reaction is released as heat, which causes the temperature to rise.
