What is the meaning of balanced equation?
A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side. Balancing chemical equations is a process of trial and error.
What is the rule for a balanced equation?
A balanced chemical equation has the same number of atoms of each element on both sides of the reaction arrow.
How do you write a balanced chemical equation?
Identify the reactants and the products in the reaction and write their chemical formulae. Write the equation by putting the reactants on the left of the arrow and the products on the right. Count the number of atoms of each element in the reactants and the number of atoms of each element in the products.
What is balance chemical equation class 10?
4. Balanced Chemical Equation: A balanced chemical equation has number atoms of each element equal on both left and right sides of the reaction. To obey this law, the total mass of elements present in reactants must be equal to the total mass of elements present in products.
What is the other name of balanced equation?
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. Also Known As: Balancing the equation, balancing the reaction, conservation of charge and mass.
How do you balance an equation algebraically?
The strategy for balancing chemical equations algebraically is as follows:Write a different letter coefficient in front of each compound in the equation.Write algebraic expressions or rules for each element that equate its atoms on the LHS and RHS.
What do you balance first in a chemical equation?
The first step in balancing a chemical equation is to identify your reactants and your products. Remember, your reactants are on the left side of your equation. The products are on the right side.
What are 3 examples of a chemical reaction?
Common Chemical ChangesThe rusting of iron.Combustion (burning) of wood.The metabolism of food in the body.Mixing an acid and a base, such as hydrochloric acid (HCl) and sodium hydroxide (NaOH)Cooking an egg.Digesting sugar with the amylase in saliva.Mixing baking soda and vinegar to produce carbon dioxide gas.
What are the rules for writing chemical equations?
Writing Chemical EquationsIn a chemical equation, the reactants are written on the left, and the products are written on the right.The coefficients next to the symbols of entities indicate the number of moles of a substance produced or used in the chemical reaction.
What is a balanced chemical equation Why should?
Why should chemical equations be balanced? Answer: According to this law, mass can neither be created nor be destroyed in a chemical reaction and obeying this law total mass of the elements or molecules present on the reactant side should be equal to the total mass of elements or molecules present on the product side.
