This is because according to the law of conservation of mass mass can neither be created nor destroyed in a chemical reaction. to prove this statement correct a chemical equation should be balanced
Chemical equations must be balanced because of the law of conservation of matter/mass, which states that in a chemical reaction, matter is neither created nor destroyed. This means that the numbers of atoms of each element in the reactants are the same as in the products, but they are rearranged to form new substances with different chemical and physical properties. Consider the equation for photosynthesis. The gas carbon dioxide reacts with water to produce the sugar glucose and the gas oxygen. If you count the number of atoms of each element on both sides of the equation, they are equal. The only thing that changed was the arrangement of the atoms.
6CO2 + 6H2O → C6H12O6 + 6O2.
To show that none of it was either created or destroyed; to also show that it was an equal equation on both sides , in which it obeys the law of conservation of mass.
An unbalanced equation represents mass either appearing or disappearing. Since tht is impossible, the equation must be balanced.
please help me

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.
B. accurate chemical calculations
False. They are balanced by changing the coefficients.

Yes, chemical equations must be balanced due to the law of conservation of matter/mass.
balanced.
Chemical equations are representative for chemical reactions.
Yes
the law of conservation of mass.

Balanced and unbalanced chemical equations have the same elements on both sides, they have just been recombinded to form new products from the reactants.

They are necessary for accurate chemical calculations.

No - they are usually balanced by changing the numbers before the molecules.
