Why is it important to show chemical reactions in a balanced form? To prove the law of conservation of mass. Compare the energy required to break the bonds of the reactants and the energy released when products form in an exergonic
Exergonic reaction
An exergonic reaction is a chemical reaction where the change in the free energy is negative (there is a net release of free energy), indicating a spontaneous reaction. For processes that take place under constant pressure and temperature conditions, the Gibbs free energy is used wherea…
How do you write a balanced chemical reaction?
- Know whats going to happen in the reaction BEFORE writing the equation. ...
- Decide if the reaction is reversible of not. ...
- Write out your products and reactants and leave plenty of space before each species for working out the stoichometry / balancing the species.
- Here’s the fun part. ...
What does it mean to balance a chemical reaction?
To balance a reaction means to make the number of atoms the same on both the reactants and products side. To do so, coefficients need to be added to the chemical equation. This balances the atoms, making the number of atoms the same on both the reactants and products side.
Why must chemical reactions always balance?
Why must chemical equations be balanced? It’s the law! Matter cannot be created or destroyed in chemical reactions. This is the law of conservation of mass. In every chemical reaction, the same mass of matter must end up in the products as started in the reactants. Balanced chemical equations show that mass is conserved in chemical reactions.
How to predict and balance chemical reactions?

Why are chemical reactions important?
It's because of chemical reactions that human beings (and all other animals) reproduce, digest, grow, heal, and think.
Why do we have chemical reactions?
In addition: Chemical reactions are how new forms of matter are made. While nuclear reactions also may produce new matter, nearly all the substances you encounter in daily life are the result of chemical changes.
Why do we observe chemical reactions in space?
By observing chemical reactions in outer space, we are able to identify and describe other planets. We can even determine which planets and moons are likely to be able to sustain life.
What are the elements that make up matter?
Elements are the basic substances that make up matter in the universe. Each element is a chemical. Elements that form bonds are called molecules. An oxygen molecule, for example, has two oxygen atoms. Chemical reactions occur when molecules interact and change.
Chemical Reactions Are Balanced
Have you ever watched an ice cube melt? It's pretty cool, right? As that solid form of water changes temperature, it melts into a puddle of liquid water right in front of you. This is what we call a physical change, which is when a substance changes its physical phase but not its chemical composition.
Components of a Chemical Equation
The 'ingredients' of a chemical reaction, or substances that react are called the reactants. Easy enough, right? These appear on the left side of the equation. Your finished cake side of the equation, the newly formed substances, are called the products. They're what you produce during the reaction.
Balancing Chemical Equations
Now that you know what a chemical equation is, and that is has to be balanced, let's look at a real-world example of how we would go about balancing a chemical equation. You may recall that photosynthesis is the process of converting sunlight into chemical energy.
