How would you describe a chemical equation?
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side with a plus sign between the entities in both the reactants and the products and an arrow that …
What is balanced chemical equation class 10th?
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 meant by balanced chemical equation why chemical equations are 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 …
What is a balanced chemical equation write 3 Characteristics of a balanced chemical equations?
The 3 characteristics of balanced equation is : 1) We can get equal no. of atoms on both the sides. 3) Desired stoichiometry of the reactant and product is determined to calculate the required amount of reactant and desired result of product.
How can you tell if a chemical equation is balanced or unbalanced?
A balanced chemical equation has an equal numbers of atoms of different elements in the side of reactants and products. An unbalanced chemical equation has an unequal number of atoms of one or more elements in the reaction.
How can you tell 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. Which means if you have 12 hydrogens on the left hand side of the equation, you must have 12 hydrogens on the right hand side, if there are 4 oxygens on the left,…
What are the steps in balancing a chemical equation?
Steps to Balancing Chemical Equations 1. Count the number of atoms of each element in the reactants and the products. List each element and how many atoms it has underneath the reactants and products. 2. To balance out the atoms add in coefficients. 3. Make sure that there are equal numbers of atoms for each element on both sides of the equation.
What are the rules in balancing chemical equations?
Identify each element found in the equation.
What is the formula for balancing chemical equations?
Therefore, the balanced chemical equation is C 3 H 8 + 5O 2 → 3CO 2 + 4H 2 O. The Algebraic Balancing Method. This method of balancing chemical equations involves assigning algebraic variables as stoichiometric coefficients to each species in the unbalanced chemical equation.
