How do you balance a chemical equation for kids?

To balance chemical equations, think of both sides as a balance that can totter. When one side is heavier it falls and the other rises. The Chemical equation is the same thing: When the equation is balanced, neither the identities nor the mass of both the reactants and the products remain unchanged.

What coefficients are needed to balance the chemical equation?

To be useful, chemical equations must always be balanced. Balanced chemical equations have the same number and type of each atom on both sides of the equation. The coefficients in a balanced equation must be the simplest whole number ratio. Mass is always conserved in chemical reactions.

Why do we need to balance chemical equation?

A chemical equation should always be balanced because the law of conservation of mass states that matter can neither be created nor destroyed so in a chemical equation the total mass of reactants must be equal to the mass of products formed i.e. the total number of atoms of each element should be equal on both the …

What are the four steps to balancing a chemical equation?

Step 1: Make a Table. In a chemical equation there are subscripts and coefficients.

Step 2: Determining and Balancing the First Element. Pick an element that appears in one molecule on the left side and in one molecule on the left.

Step 3: Balancing Hydrogen.

Step 4: Balancing Oxygen.

Why is it important to balance a chemical equation for kids?

we need to balance a chemical equation because “law of conservation of mass” state that mass can neither be created nor destroyed in a chemical reaction. So number of elements involved in a chemical reaction should remain same at reactant and product side.

Is Zn HCl ZnCl2 H2 balanced?

Explanation: The equation has one reactant’s atom(s) given to the other reactant, causing a single replacement. Zinc reacts with HCl to form ZnCl2(aq) & H2(g). Balanced equation: Zn(s) + 2 HCl(aq) = H2(g) + ZnCl2(aq).
