: List how many atoms of each element are on the reactant (left) and product (right) sides.
The foundation of balancing equations is the . This scientific principle states that matter cannot be created or destroyed in a closed system. In chemistry terms, the atoms you start with (reactants) must equal the atoms you end with (products)—they just get rearranged into new substances. The Anatomy of an Equation what is a balanced chemical equation
H2+O2→H2Ocap H sub 2 plus cap O sub 2 right arrow cap H sub 2 cap O : List how many atoms of each element
Now, there are 4 Hydrogen atoms and 2 Oxygen atoms on both sides. The "account books" are closed, and the mass is conserved! 3 Steps to Balance Any Equation what is a balanced chemical equation
