In the following reaction, the total number of oxygen atoms in X and Y is______ Na 2 O + H 2 O → 2 X Cl 2 O 7 + H 2 O → 2 Y

Correct answer

0

Step-by-step solution

Let's first balance the two given chemical equations: Na 2 O + H 2 O ⟶ 2 NaOH X In this equation, there are two NaOH molecules, so the total number of oxygen atoms in the products is 1 . Cl 2 O 7 + H 2 O ⟶ 2 HClO 4 Y In this equation, there are two HClO 4 molecules, so the total number of oxygen atoms in the products is 4 . So X has one O and Y has four O .
