Matter is conserved in a chemical reaction, meaning nothing "disappears" when compounds react. Accordingly, the number of atoms you start with has to be the number of atoms you end with. Similarly, no element can become another element, so there must be the same number of each kind of atom at the start and at the end.
If you don't balance the equation, you cannot use it to calculate yield. When you balance the equation, you are applying the law of 'Conservation of Mass' or as some like to include 'Conservation of Mass and Energy'.

How Chemical equations are balanced by changing the subscripts of the molecule true or false?
False. Chemical equations are balanced by changing the coefficients in front of the chemical formulas, not the subscripts within the formulas. The number of atoms of each element must be equal on both sides of the equation to ensure that mass is conserved.
What is a balanced chemical equation Why should chemical equations be balanced?
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.
What is balanced chemical equations demonstrate?
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.
Why must chemical equations must be balanced?
Chemical equations need to be balanced to satisfy the law of conservation of mass, which states that mass is neither created nor destroyed in a chemical reaction. Balancing the equation ensures that the same number and types of atoms are present on both sides of the reaction, maintaining mass consistency.
Why does the law of conservation of mass dictate the chemical equations be p why does the law of conservation of mass dictate the chemical equations be balanced?
The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction, only rearranged. In order to adhere to this law, chemical equations must be balanced to ensure that the same number of each type of atom is present on both the reactant and product sides of the equation. This balancing of chemical equations ensures that mass is conserved throughout the reaction.
Is chemical equations required to be balanced?
Yes, chemical equations must be balanced due to the law of conservation of matter/mass.
What is the formula for chemical equations is balanced?
The number of reactants atoms must be equal to the number of products atoms.
How Chemical equations are balanced by changing the subscripts of the molecule true or false?
False. Chemical equations are balanced by changing the coefficients in front of the chemical formulas, not the subscripts within the formulas. The number of atoms of each element must be equal on both sides of the equation to ensure that mass is conserved.
Why must chemical equations be balanced using coefficients?
The number of atoms in the reactant and products must be equal to obey the law of conservation of mass.
What is a balanced chemical equation Why should chemical equations be balanced?
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.
What is a chemical equation balanced does it show?
Chemical equations are representative for chemical reactions.
What do balanced and unbalanced chemical equations share in common?
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.
What is balanced chemical equations demonstrate?
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.
Are chemical equations balanced by changing the subscripts of the molecules?
No - they are usually balanced by changing the numbers before the molecules.
Balanced equations reflect the law of conservation of?
Balanced equations reflect the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction, only rearranged. This means that the total mass of the reactants must equal the total mass of the products in a chemical reaction.
Why must chemical equations must be balanced?
Chemical equations need to be balanced to satisfy the law of conservation of mass, which states that mass is neither created nor destroyed in a chemical reaction. Balancing the equation ensures that the same number and types of atoms are present on both sides of the reaction, maintaining mass consistency.
