1. You cannot change the subscript just to help you balance the equation. You can only balance an equation by using whole-number coefficients written at the beginning of a substance.
2. If no subscript is present, you can't just add one to help you balance the equation for same reason listed above.

Where can you compare balancing chemical equation in real life?
We can compare balancing chemical equation to a mother and her children. She should be fair in giving the things that her children want. She should be equal. :)
How do you banlance chemical equations?
You add whole number coefficients before each substance in the equation as needed until the number of atoms on the reactant side equals the number of atoms on the product side. For example, in the unbalanced equation: Cu + AlCl3 --> CuCl2 + Al, the number of copper and chlorine atoms on one side does not equal the other side. However, by adding coefficients to make the equation read 3Cu + 2AlCl3 --> 3CuCl2 + 2Al, everything adds up. Things to remember: balancing a chemical equation upholds the Law of Conservation of Mass, which states that matter cannot be created or destroyed; and also the coefficients in a balanced chemical equation represent mole ratios.
How is balancing an equation and law of conservation of mass?
Balancing an equation means ensuring that the number of atoms of each element is equal on both sides of the equation. This process is essential to satisfy the law of conservation of mass, which states that mass cannot be created or destroyed in a chemical reaction. Balancing an equation ensures that the total mass of the reactants equals the total mass of the products, maintaining this fundamental law.
Is things that rot a chemical change or a physical change?
Rotting is a chemical change because it involves the breakdown of organic molecules into simpler substances through chemical reactions. This process cannot be reversed and results in the formation of new compounds.
How is a balanced equation similar to a recipe?
The aré alike because a chemical symbol tells you what to put together to make a molecule like a recipe tells you what to mix together to make food or a drink
What symbolic representation of a chemical reaction?
A chemical reaction can be symbolically represented using a chemical equation, where reactants are shown on the left side and products are shown on the right side. The equation includes chemical formulas of the substances involved and indicates the balance of atoms before and after the reaction.

What do you call the things on the left-hand side of an equation?
If you are referring to a chemical equation, the items on the left hand side are called the reactants.
What is a shorthand way of writing a chemical reaction?
A chemical reaction is always written with the reactants (the things you mix together to do the reaction) on the left and the products (the stuff you get) on the right. In between is an arrow pointing right to indicate that the reactants react and become the products. Catalysts are sometimes listed above the arrow. And don't forget to balance the equation.

What is the scientific equation?
Scienitifc equation is a equation that has lots of scientifical things
Why cant the subscripts of a chemical equation be changed?
The subscripts in a chemical equation represent the number of atoms of each element involved in the reaction. Changing the subscripts would alter the stoichiometry of the reaction, resulting in a different chemical compound being formed. This would violate the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Therefore, the subscripts in a chemical equation must remain constant to accurately represent the reactants and products involved.
What is a reactant in a chemical equation?
A reactant is something that reacts with another thing(s) in a word equation to make something else (the things made are the 'products'). So an example is:CARBON + OXYGEN -> CARBON DIOXIDE + WATERCarbon and oxygen are the reactants and carbon dioxide and water are the products.This word equation as a symbol equation is:C + O2 -> CO2 + H20
What two things must we remember when balancing chemical equations?
When balancing chemical equations, it is important to remember to adjust coefficients (not subscripts) to ensure that the number of atoms of each element is equal on both sides of the equation. Additionally, it's crucial to balance one element at a time and to double-check the final equation to confirm that it is balanced.
Write the word equations and chemical equation for the reactions of sodium with oxygen?
The word equations for the reactions of sodium with oxygen are: "sodium + oxygen → sodium oxide" and "sodium + oxygen → sodium peroxide." The chemical equation for the formation of sodium oxide is 4Na + O2 → 2Na2O, and for the formation of sodium peroxide is 2Na + O2 → Na2O2. These reactions illustrate the different oxidation states of sodium when it reacts with oxygen.
Where do bacteria get the energy they need from?
