What is an unbalanced chemical equation?
If the number of atoms of each element in reactants is not equal to the number of atoms of each element present in product, then the chemical equation is called unbalanced chemical equation.
What is a balanced chemical equation define?
Balanced chemical equation – A chemical equation in which the number of each type of atom is equal on the two sides of the equation. Subscripts – Part of the chemical formulas of the reactants and products that indicate the number of atoms of the preceding element.
What is balance chemical equation class 10?
Answer: The representation of a chemical reaction in the form of substances is known as a chemical equation. The equation in which the number of atoms of all the molecules is equal on both sides of the equation is known as a balanced chemical equation.
What is an example of a balanced chemical equation?
A balanced chemical equation occurs when the number of the atoms involved in the reactants side is equal to the number of atoms in the products side. In this chemical reaction, nitrogen (N2) reacts with hydrogen (H) to produce ammonia (NH3). The reactants are nitrogen and hydrogen, and the product is ammonia.
What is balanced chemical equation and why it should be balanced?
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 …
How do you write a balanced chemical equation?
Write a balanced chemical equation for. Sodium(s) + hydrochloric acid(aq) → sodium chloride(aq) + hydrogen(g) Solution: Step 1: Convert the chemical names into chemical formulas. Place them based on the chemical equation and write the state symbols.
What chemical equation is properly balanced?
The balanced chemical equation for this combustion reaction is: Now this equation is stoichiometrically balanced: it is balanced with respect to charge as well as mass. For every carbon atom reactant particle, there is a carbon atom product particle; the same for hydrogen; and the same for oxygen.
Why should all chemical equations be balanced?
Balancing a chemical equation is important because it shows the ratio of elements needed for the reaction to proceed properly. This allows scientists and researchers to use mathematical formulas to determine how much of one reactant is needed to produce the product.
How do you know if a chemical equation is balanced?
A chemical equation is balanced when the number of atoms of each type on each side of the equation is the same.
