Why must reactants mass the same as products?

The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant.... see details ›

Why do the amount of reactants and products not change?

All reactions tend towards a state of chemical equilibrium, the point at which both the forward process and the reverse process are taking place at the same rate. Since the forward and reverse rates are equal, the concentrations of the reactants and products are constant at equilibrium.... see details ›

Why is the total mass of reactants equal to the total mass of products?

"In a chemical reaction, the total mass of the reactants is equal to the total mass of the products" This means there is no change in mass during a chemical reaction.... view details ›

What is the purpose of balancing chemical reaction equations?

The purpose of balancing chemical reactions is to conserve the mass of the system. The answer is B) law of conservation of mass. The process is done by appending proper coefficients to the substances in the solution in order to have an equal number of atoms per element on each side of the equation.... see details ›

What is the most important thing about balancing chemical equations?

This is important because a chemical equation must obey the law of conservation of mass and the law of constant proportions, i.e. the same number of atoms of each element must exist on the reactant side and the product side of the equation.... view details ›

Why is it so important to balance the equation before answering any questions about it?

Why is it important to balance a chemical equation before proceeding to answer questions about it? It's important to balance a chemical equation because there must be an equal number of atoms on both sides of the equation to follow the Law of the Conservation of Mass.... continue reading ›

What will happen if number of protons and electrons not equal?

When the number of electrons does not equal the number of protons, the atom is ionized. (The atom is then called an ion).... read more ›

What happens if the number of electrons and protons in an atom is not equal?

In an electrically neutral ATOM, the number of electrons equals the number of protons. However, an ION is an atom (or group of atoms) which has either gained or lost some electrons, so for an ION the number of electrons does not equal the number of protons.... see details ›

Why is the atomic number more appropriately equal to the number of protons?

The atomic number equals the charge on the nucleus. It therefore also equals the number of protons in the nucleus and also equals numerically the number of electrons in the neutral atom.... read more ›

What is the relation between the number of atoms of the reactants and products?

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.... continue reading ›

Do the number of atoms stay the same in a chemical reaction?

In a chemical reaction the total mass of all the substances taking part in the reaction remains the same. Also, the number of atoms in a reaction remains the same. Mass cannot be created or destroyed in a chemical reaction.... see more ›

Why should the number of atoms of each element remain constant?

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 before and after a chemical reaction.... read more ›

How do you count the number of atoms in the reactant side and the product side of the equation?

A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction is equal on the reactant and product side.... see more ›

Why two atoms of the same element Cannot have different atomic numbers but can have different mass numbers?

Every atom of an element will have the same number of protons in its nucleus. This is how we set apart different elements. Therefore, if two elements were to have the same mass numbers but a different atomic number, they cannot be considered atoms of the same element.... continue reading ›

Why doesnt changing the number of neutrons in an element change its chemistry?

Neutrons and protons do not take part in chemical reactions, only electrons do. So changing the number of neutrons or protons would just result in a change in the physical properties of the atom as neutrons and protons give the physical characteristic of an atom.... see details ›

Do atoms of the same element always have the same number of neutrons?

The number of neutrons can be different, even in atoms of the same element. Atoms of the same element that contain the same number of protons, but different numbers of neutrons, are known as isotopes.... view details ›

Why the number of atoms in both reactant and product is equal according to the law of conservation of mass?
