Question

Which one of the following pairs is obtained on heating ammonium dichromate?

• A. $N_{2}$ and $H_{2}O$
• B. $N_{2}O$ and $H_{2}O$
• C. $NO_{2}$ and $H_{2}O$
• D. NO and $NO_{2}$

Answer 1

Answer: (A)

$N_{2}$ and $H_{2}O$

Answer 2

Ammonium dichromate on heating gives nitrogen, chromic oxide and water.
$(NH_{4})_{2}Cr_{2}O_{7}\xrightarrow{\Delta }N_{2}+Cr_{2}O_{3}+4H_{2}O$
