What is balancing a chemical equation so that the same number of atoms of each element is found in both the reactants and the products is an example of what?
the law of conservation of matter (or mass)
Why does a chemical equation have to be balanced?
Balancing Chemical Equations is absolutely essential if you want to determine quantities of reactants or products. An unbalanced chemical equation gives only the identify of the beginning reactants and the final products using the appropriate formulas as well as the conditions of temperature, physical state, and pressure conditions under which the reaction is to operate under. However an unbalanced equation can say nothing about the quantities involved until the equation has been balanced. A balanced equation assures that the conservation law of matter is obeyed. The total mass of reactants must equal the total mass of products. A balanced equation tells you the proportional quantities of each substance involved.
How does law of the conservation of mass apply to chemical reactions?
The Law of Conservation of Mass applies to chemical changes. When considering a chemical change this would mean that the total mass of all of the reactants in the chemical reaction is equal to the total mass of products in the chemical reaction.
If a chemical equation is not balanced it violates what law?
If a chemical equation is not balanced, it implies that one side of the equation has more mass than the other side. Therefore, it violates the Law of Conservation of Mass.
Why is it important to balance an equation?
being able to write a balanced equation for a reaction is very important. By balancing an equation we can tell how much material we will need to start with, what the likely products to form, and how much of these products will form
Which law physical science must be followed when balancing chemical equations?
the law of conservation of mass
The balancing of chemical equations is dictated by?
Chemical equations usually do not come already balanced. A balanced equation has equal numbers of each type of atom on each side of the equation.A chemical equation is balanced by balancing the number of atoms on products and reactants side.
What chemical equations violates the law of conservation of energy?
Any chemical equations violates the law of conservation of energy.
What have you learned after balancing chemical equations?
being able to write a balanced equation for a reaction is very important. By balancing an equation we can tell how much material we will need to start with, what the likely products to form, and how much of these products will form
Why chemical equations need to be balanced according to the law of the conservation of mass?
becasuse atoms are never gained or lost in a chemical reaction
How does balancing equations relate to the conservation of mass and how was the law verified?
The mass of reactants is equal to the mass of products.
What is the law of conservation mass and how is it connected to balancing chemical equations?
The law of conservation of matter/mass states that in a closed system matter is neither created nor destroyed. This means that the same number and kind of atoms in the reactants are also present in the products, which is why a chemical equation must be balanced.
Is chemical equations required to be balanced?
Yes, chemical equations must be balanced due to the law of conservation of matter/mass.
Why should chemical equation be balaced?
Equations should be balanced because of a basic scientific law known as the Law of Conservation of Mass. The Law simply means that all the mass you start with in a chemical reaction should be present at the end. Balancing the equation allows scientists to mathematically predict how much matter there should be at the end of a reaction.
What is true of the total mass of reactants compared to the total mass of products?
The two are equal. The Law of Conservation of Mass state that in a chemical reaction matter is neither created nor destroyed. That is the whole point of balancing chemical equations.
Balanced chemical equations demonstrate?
the law of conservation of mass.
What are chemical equations based on?
They are based on the chemical composition of reactants and products; law of mass conservation.
