Observe the two chemical equations given below.
P) Ca(OH) 2 + HNO 3 -----> Ca(NO 3 ) 2 + H 2 O
Q) KBr + AgNO 3 -----> KNO 3 + AgBr
(a) Explain how a balanced equation can be identified.
(b) Which of the two equations is/are NOT balanced? Balance the equation(s) by rewriting.
(a) When we balance an equation, we are trying to make sure that both sides have equal no of each atom, so as to conserve mass on both sides .
- Therefore, the number of atoms of each element should be the same on the reactants' side and the products' side.
Balanced equation: Ca(OH) 2 + 2 HNO 3 -----> Ca(NO 3 ) 2 + 2 H 2 O
