The number of reactants atoms must be equal to the number of products atoms.
Yes, chemical equations must be balanced due to the law of conservation of matter/mass.
Chemical equations are representative for chemical reactions.
Both balanced and unbalanced chemical equations represent the chemical reactions that take place between reactants to form products. The key difference is that balanced equations have an equal number of atoms of each element on both sides, while unbalanced equations do not.
Balanced chemical equations demonstrate the conservation of mass and atoms in a chemical reaction. They show the ratio of reactants and products involved in a reaction and help predict the outcomes of chemical reactions.
No - they are usually balanced by changing the numbers before the molecules.
the law of conservation of mass.
They are necessary for accurate chemical calculations.
Properly balanced equations are necessary in chemistry to accurately represent the conservation of mass and atoms in a chemical reaction. Balanced equations ensure that all reactants are accounted for and that the number of atoms remain the same on both sides of the reaction.
Proteins have a very complicate chemical formula but not a "balanced chemical equation".
A balanced equation is when the amount of molecules reacting are equal to the amount of molecules being produced. Chemical equations must be balanced because no energy/mass is ever lost when a reaction takes place. This is because atoms are simply arranged.
Yes.
Chemical equations are always balanced to satisfy the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Balancing equations ensures that the number of atoms of each element on the reactant side is equal to the number of atoms of the same element on the product side.
