In a chemical reaction, which is what a chemical equation represents, the numbers of atoms of each element are the same in the reactants and the products. This is because, in a chemical reaction, the atoms in the reactants are not changed, they are simply rearranged into new compounds in the products. Therefore, matter is neither created nor destroyed. This is why it's important to balance a chemical equation properly so that the numbers of atoms of each element is equal on both sides.
Ca+O2>CaO2
true
False
Mass of reactants (at the right) is equal to the mass of products at the left.
because the total mass of the reactions in a chemical reaction is the same as the total mass of the products.
a balanced chemical equation according to the law of conservation of mass is that equation in which both the products side atoms are equal to the reactants side atoms.BEfore and after the chemical reaction.
The law of conservation of mass means that the same number of each atom must be present on both sides of the equation, so that the mass of the reactants equals the mass of the products.
The mass of reactants is equal to the mass of products.
A chemical equation must respect the law of mass conservation.
In a balanced chemical equation, the number of atoms of each element are the same on both sides; they are just rearranged. This is due to the conservation of mass.
4Fe + 3O2 -> 2Fe2O3
Ca+O2>CaO2
true
The law of conservation of mass, which states that in a closed system, mass is neither created nor destroyed, it can only change form. This means that in a chemical reaction that takes place in a closed system, the mass of the reactants equals the mass of the products.
A balanced chemical reaction obeys the law of conservation of mass, because the same number of atoms of each element must appear on both sides of the equation for the reaction, and in any actual reaction, the same exact atoms will be found on both sides of the equation.
The law of conservation of mass states that in any chemical reaction, matter is neither created nor destroyed. Therefore, in a balanced chemical equation you must have the same number of atoms of each element 1) on either side of the equation.1) ImprovementAlso the conservation of 'Elements' comes into my mind: it is necessarily for a well balanced equation. If we sort out 'Nuclear Reactions' then this is a true case!
