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
In a redox reaction the numbers of some of the elements changes from the reactants to the products?
In a redox reaction the OXIDATION numbers of some of the elements change from the reactants to the products. The numbers of atoms each element never changes in any chemical reaction.
Will new atoms form when a reactant breaks down in to two or more products?
No. New molecules will form, or a molecule will break down into its component atoms. A chemical reaction never creates or consumes atoms; it only changes how they are bonded to one another.
What happens when a compound undergoes a chemical reaction?
When a compound undergoes a chemical reaction, it is forever altered. It can never go back to the way it was before the reaction took place.
How is a chemical equation defined?
When a chemical reaction occurs, it can be described by an equation. This shows the chemicals that react (called the reactants) on the left-hand side, and the chemicals that they produce (called the products) on the right-hand side. The chemicals can be represented by their names or by their chemical symbols. Unlike mathematical equations, the two sides are separated by an arrow, that indicates that the reactants form the products and not the other way round. Any chemical change in substance whether combination, decomposition, displacement or arrangement of the molecules of the substance which involves the transformation of matter into a new substance is termed as chemical equation.
Is it possible to entirely stop a chemical reaction from happening?
A chemical reaction can end when the limiting reagent runs out, but atomic motion; i.e. the motion of atoms and of subatomic particles within atoms, never stops.
Is energy created when atoms are destroyed in a chemical reaction?
Atoms are never created or destroyed in a chemical reaction. There are the same number of each type of atom both before and after a chemical reaction. Atoms are never created of destroyed; the molecules are just re-arranged in their bonding with each other.
What is never gained or lost in a chemical reaction?
Matter is never lost or gained in a chemical reaction. A chemical reaction cannot destroy or create atoms, it merely rearranges how they are connected and arranged in new molecules. While the atoms rearrange, energy is released (such as through light, fire or heat), or absorbed, (such as when plants use sunlight to make sugar out of carbon and water). Some atoms may evaporate, making the resulting product seem lighter or smaller, such as when coal or wood burns, but the atoms themselves are not destroyed.
How a balanced chemical equation really illustrate that mass is never lost or gained in a chemical reaction?
The kinds of atoms and the number of each kind are the same on both sides of a balanced chemical equation.
A chemical reaction creates something that has never existed in any form before?
Generally no. Unless the chemical reaction involves nuclear fission or fusion, you can only rearrange existing components; you cannot create new atoms.
Is it possible to convert atoms of one element to atoms of another?
According to Dalton's atomic theory chemical reactions occur when atoms are separated, joined, or rearranged. Atoms of one element, however, are never changed into atoms of another element as a result of a chemical reaction (it is possible only during nuclear reactions and radioactive disintegration).
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
In a redox reaction the numbers of some of the elements changes from the reactants to the products?
In a redox reaction the OXIDATION numbers of some of the elements change from the reactants to the products. The numbers of atoms each element never changes in any chemical reaction.
Are atoms created or distroyed in a chemical?
i think that in nuclear reactions but in normal reaction not created and destroyedAdded:No, never created or destroyed. Only in nuclear reactions some atoms may change in other atoms (by decay or fusion) but still not (totally) distroyed.
Will new atoms form when a reactant breaks down in to two or more products?
No. New molecules will form, or a molecule will break down into its component atoms. A chemical reaction never creates or consumes atoms; it only changes how they are bonded to one another.
Why are atoms never created or destroyed during a chemical reaction-?
The Law of Conservation of Mass states that matter cannot be created nor destroyed. Since atoms comprise matter, any reaction must involve the same number of atoms on the reactants side and the product side.
How does a balanced chemical equations how that mass is never lost or gained in a chemical reaction?
if you balanced the equation correctly then the sum of the reactants will equal the sum of the the products because if there is the same amount of atoms on the reactants and the products obviously none is lost.
