In the following reaction, the total number of oxygen atoms in X and Y is _______.
Na$$_2$$O + H$$_2$$O $$\to$$ 2X
Cl$$_2$$O$$_7$$ + H$$_2$$O $$\to$$ 2Y
Correct Answer: 5
Reaction 1: $$Na_2O + H_2O \to 2NaOH$$
So X = NaOH (1 oxygen atom per molecule)
Reaction 2: $$Cl_2O_7 + H_2O \to 2HClO_4$$
So Y = HClO₄ (4 oxygen atoms per molecule)
Total oxygen atoms in X and Y = 1 + 4 = 5.
