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.... read more ›

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

The atoms in the reactants are shown on the left side of the equation. The atoms in the products are shown on the right side of the equation. Because atoms are rearranged and not created or destroyed, the number of atoms of each different element must be the same on each side of the equation.... see details ›

Do reactants and products have the same number of molecules?

The number of atoms is conserved during the reaction. However, you will also see that the number of molecules in the reactants and products are not the same. The number of molecules is not conserved during the reaction.... see more ›

Why the mass of the products and reactants are the same?

Mass of reactants is equal to mass of products if the reaction has same number of atoms of different elements on either side of the chemical equation respectively.... see details ›

Why do the numbers of atoms have to stay the same?

Because atoms of an element has, essentially, the same number of protons.... read more ›

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.... continue reading ›

Why are the number and types of atoms on the reactant side equal to the number and types of atoms on the product side?

According to the Law of Conservation of Mass (Matter), atoms are neither created nor destroyed when chemical reactions take place. Therefore, the number of atoms of each element must be identical on the reactant (left) and the product (right) sides of a balanced chemical reaction.... see details ›

Why are the number of atoms on each side of the chemical equation the same?

3. The law of conservation of mass must be satisfied. Atoms are neither created nor destroyed in ordinary chemical reactions. Therefore, the same number of atoms of each element must appear on each side of a correct chemical equation.... read more ›

Why do the number of atoms on each side of the equations have to be equal?

The bonds between atoms in the reactants are rearranged to form new compounds in chemical reactions, but none of the atoms disappear and no new ones are formed. As a consequence, chemical equations must be balanced, meaning that the number and kinds of atoms must be the same on both sides of the reaction arrow.... see more ›

Does the product or reactant have more atoms?

Explain that mass is conserved in a chemical reaction.

There are the same number of each type of atom on both the reactant side and the product side of the chemical equation we explored.... see more ›

When reactants and products are equal?

Equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time. Usually, this state results when the forward reaction proceeds at the same rate as the reverse reaction.... view details ›

Do reactants and products have to be equal?

The amount of reactants and products do not have to be equal. However, after equilibrium is attained, the amounts of reactants and products will be constant.... view details ›

What is the main similarity between products and reactants?

Similarities Between Reactants and Products

Reactants and products can be atoms, ions or molecules. Both reactants and products are present in the reaction mixture. Reactants and products can be used to determine the rate of a chemical reaction.... read more ›

Is there any reason the products mass should equal the reactants mass?

Explanation: According to the Law of Conservation of Mass, mass cannot be created or destroyed. Therefore in any chemical reaction the mass of the products must equal the mass of the reactants.... see details ›

Why are all atoms equal?

An atom contains equal numbers of protons and electrons . Since protons and electrons have equal and opposite charges , this means that atoms are neutral overall.... continue reading ›

What does same number of atoms mean?

So, if the atomic number of atoms is the same, the number and therefore mass of the protons would also be the same. But we know that if the mass number of the atoms is different, the number of neutrons is different.... see more ›

What number is always the same for atoms of the same element?

Atoms of the same element always have the same number of protons, same Z, but often have different numbers of neutrons, therefore, different mass numbers.... read more ›

Do reactants have fewer atoms than products?

Point out that the type and number of atoms in the reactants and in the products are exactly the same. This is an important concept in chemistry: In a chemical reaction, all the atoms in the reactants end up in the products. When an equation of a chemical reaction is written, it is “balanced” to show this.... read more ›

Why do the concentrations of the products and reactants remain constant?

The rates of both the forward and the reverse reactions are equal and thus the rate at which the products are formed is the same as the rate at which the reactants are produced. Thus, the concentrations of the products and the reactants remain constant.... read more ›

Why does the number of atoms not change in a chemical reaction?

The total number of atoms does not change in a chemical reaction. This is commonly known as the Law of Conservation of Matter. Because matter cannot be created or destroyed, atoms can only rearrange themselves in a chemical reaction.... see details ›

Why do the number of atoms for each element in the reactants side have to balance the number of atoms that are present in the products side?

Explanation: According to the Law of Conservation, all atoms of the reactant(s) must equal the atoms of the product(s). As a result, we need to balance chemical equations.... continue reading ›

Why are there the same number of particles after a reaction?

Remember that in a chemical reaction, matter is neither created nor destroyed and atoms cannot change their identity (e.g. a carbon atom can't become an Iron atom); this means that you have to have the same number of each type of atom on each side of the chemical equation.... see more ›

Why do all atoms of the same element contain the same number of neutrons?

Atoms of the same chemical element do not always have the same mass because, although the number of protons in the nucleus is the same for all atoms of the same element, the number of neutrons is not. Most elements as they occur naturally on earth are mixtures of several isotopes.... continue reading ›

Why do we do the same thing to both sides of an equation?

It comes down to what the equals sign means. It means, as @MaliceVidrine says, that the two things mentioned on either side of the equation are the same thing. If you do something to the left side, you have presumably changed it.... see more ›

What does it mean when both sides of an equation are the same?

Sometimes people refer to this as keeping the equation “balanced”. If you think of an equation as being like a balance scale, the quantities on each side of the equation are equal, or balanced.... read more ›

Are the numbers of atoms in the reactants are the same on the product side how does the chemical change affect the composition of material?

The reactants and products in a chemical reaction contain the same atoms, but they are rearranged during the reaction. As a result, the atoms end up in different combinations in the products. This makes the products new substances that are chemically different from the reactants.... read more ›

How do you find the number of atoms in a reactant?

To find out the number of atoms: MULTIPLY all the SUBSCRIPTS in the molecule by the COEFFICIENT. (This will give you the number of atoms of each element.)... read more ›

What type of reaction if the reactants and products have same phase?

An equilibrated system that contains products and reactants in a single phase is a homogeneous equilibrium; a system whose reactants, products, or both are in more than one phase is a heterogeneous equilibrium.... see more ›

Do products and reactants have the same energy?

In an endothermic reaction, the products have more stored chemical energy than the reactants. This is represented by the graph on the left in the Figure below. In an exothermic reaction, the opposite is true. The products have less stored chemical energy than the reactants.... see details ›

How are reactants related to products?

The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.... see more ›

What is the difference between reactants and products quizlet?

The reactants are the substances that start the chemical reaction. The products are the substances that are produced in the chemical reaction.... continue reading ›

What is difference between reactants and products and example?

The primary difference between reactants and products is that reactants are consumed during the reaction, whereas products are produced as a result of the reaction.... see details ›

What states that the mass of reactants must always equal the mass of products?

The law of conservation of mass states that, during a chemical reaction, the total mass of the products must be equal to the total mass of the reactants.... read more ›

Why must all chemical equations be balanced?

Can a product be more than the reactant?

Sure. The products can't have more energy than the reactants. But they can have more volume. There is no conservation law for that.... view details ›

What are reactants and products short answer?

A reactant is a substance that is present at the start of a chemical reaction. The substance(s) to the right of the arrow are called products. A product is a substance that is present at the end of a chemical reaction.... read more ›

What is the relationship between reactant and product?

Explanation: The products have less energy than the reactants. The energy given off is experienced as heat and sometimes also light.... view details ›

What is the relationship between the amount of reactants and products?

Based on the Law of Conservation of Mass, which states that matter is neither created nor destroyed in a chemical reaction, every chemical reaction has the same elements in its reactants and products, though the elements they are paired up with often change in a reaction.... read more ›
