Why must the number and type of atoms be the same in the products of a chemical reaction as in the reactants?

Why must the number and type of atoms be the same in the products of a chemical reaction as in the reactants?

The law of conservation of matter says that matter cannot be created or destroyed. In chemical equations, the number of atoms of each element in the reactants must be the same as the number of atoms of each element in the products. There are two oxygen atoms in the reactants and two atoms of oxygen in the product.

Why must the reactants equal the products in both mass and number of each element?

Every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. Therefore, there must be the same number of atoms of each element on each side of a chemical equation.

Why do the reactants and products need to be balanced?

According to the law of conservation of mass, the mass of the reactants should be equal to the mass of the products when a chemical reaction occurs. The chemical equation needs to be balanced so that it follows the law of conservation of mass.

Why must the number of atoms on either side of the arrow be equal to each other in a chemical equation?

A: All chemical equations must be balanced. This means that there must be the same number of each type of atom on both sides of the arrow. That’s because mass is always conserved in chemical reactions. Count the number of hydrogen and oxygen atoms on each side of the arrow.

How do you calculate reactants?

The reacting materials (reactants) are given on the left, and the products are displayed on the right, usually separated by an arrow showing the direction of the reaction. The numerical coefficients next to each chemical entity denote the proportion of that chemical entity before and after the reaction.

Why are reactants equal to the number of products?

The number of reactants atoms must be equal to the number of products atoms. Why the number of atoms of reactants must equal the number of atoms of products formed? Only then it will obey the law of conservation of mass. How do you kow when a chemical equation is balanced? The number of atoms for reactants and products must be equal.

How does the number of atoms of each reactant compare?

In the chemical equation, how do the number of atoms of each element in the reactants compare to the number of atoms of each element in the products? Atoms of the reactant (s) must equal the atoms of the product (s).

How does stoichiometry describe the relationship between reactants and products?

Chemical reactions are balanced by adding coefficients so that the number of atoms of each element is the same on both sides. Stoichiometry describes the relationship between the amounts of reactants and products in a reaction.

Why are reactants needed in a balanced equation?

Therefore, in a balanced equation each side of the chemical equation must have the same quantity of each element. Chemical equations A chemical equation shows what reactants are needed to make specific products.
