In the following reactions, the total number of oxygen atoms in X and Y is _______
Na2O + H2O → 2X
Cl2O7 + H2O → 2Y
Na2O + H2O → 2X
Cl2O7 + H2O → 2Y
Show Hint
In reactions involving oxides and water, carefully balance the equations and count the atoms to ensure accuracy in stoichiometry
Correct Answer: 5
Solution and Explanation
The reactions of sodium oxide and dichlorine heptoxide with water are as follows:
\[ Na_2O + H_2O \rightarrow 2NaOH \]
\[ Cl_2O_7 + H_2O \rightarrow 2HClO_4 \]
Adding the coefficients from both equations: 1 +4=5
