Question

2. Read the following and answer questions from (i) to (v).

A chemical equation is a representation of chemical change in terms of symbols and formulae

of reactants and products. A word equation shows change of reactants to products through an

arrow placed between them. The substances which react are written on the left-hand side of

the arrow and are termed as reactants while the substances produced as a result of reaction are

called products and are written on the right-hand side of the arrow. The arrowhead points

towards the products and show the direction of the reaction. A chemical equation in which the

number of atoms of each element on reactant side is equal to that on the product side is called

a balanced chemical equation


(i) In which of the following equations, the mass is not same on both the sides?


(a) Word equation
(b) Skeletal equation
(c) Balanced equation
(d) Both (a) and (b)​

Answer 1

Answer:-

Skeletal Equation is the the required answer

So, the correct option is (B) Skeletal Equation .

Skeletal Equation is also called Unbalanced Equation.

Additional Information !!

What is Skeletal Equation ?

Ans:- Equation in which the number of atoms of different elements (One or more ) is not equal on the two side of the equation is called on balance or skeletal equation.

For example :-

$:\implies$ Fe + H₂O → Fe₃0₄ + H₂

here , LHS ≠ RHS

What is Balanced Chemical Equation ?

Ans:- Equation in which the number of atoms of each element on the two side of the equation are equal is called balanced chemical equation .

For example :-

$:\implies$ 3Fe + 4H₂0 → Fe₃0₄ + 4H₂

Here, LHS = RHS

Answer 2

Answer:

$\purple{ \boxed{\texttt{Answer}}}$

(i) In which of the following equations, the mass is not same on both the sides?

(b) Skeletal equation .

Extra Knowledge :-

The five basic types of chemical reactions are :-

• combination,
• decomposition,
• single-replacement, double-replacement,
• combustion.

$\curlyeqsucc$ Skeletal equation :-

• Skeletal chemical equation is a representation of a chemical reaction using chemical formulae of reactants and products.
• For example: Mg + O2 → MgO, it's a skeleton equation.

$\curlyeqsucc$ Word equation :-

• A word equation is an expression of a chemical reaction or mathematical equation using words rather than letters, numbers, and operators.
