Question

Consider the following chemical equation: $p \mathrm{Al}+q \mathrm{H}_{2} \mathrm{O} ightarrow r \mathrm{Al}_{2} \mathrm{O}_{3}+s \mathrm{H}_{2}$\ To balance this chemical equation, the values of ' $p$ ', ' $q$ ', ' $r$ ' and ' $s$ ' must be respectively\

Professor PC Thomas Classes · Answer

(c):Balanced chemical equation is, $2 \mathrm{Al}+3 \mathrm{H}_{2} \mathrm{O} \longrightarrow \mathrm{Al}_{2} \mathrm{O}_{3}+3 \mathrm{H}_{2}$\ Hence, $p=2, q=3, r=1$ and $s=3$ \Concept-While balancing a chemical equation, the number of atoms of each element on both the sides of the equation should be made equal.
