Consider the following reaction and based on the reaction answer the question that follow:
`(NH_4)_2 Cr_2 O_7 to N_2 (g)+ 4H_2 O (g) + Cr_2 O_3`
Calculate :
The mass in grams of `Cr_2 O_3` formed at the same time
[Atomic massess : H= 1 , Cr = 52 , N= 14]

Explanation

To solve the problem, we need to calculate the mass of chromium oxide (Cr₂O₃) formed from the decomposition of ammonium dichromate ((NH₄)₂Cr₂O₇). Follow these steps:

### Step 1: Write the balanced chemical equation
The decomposition reaction is given as:
\[ (NH_4)_2 Cr_2 O_7 \rightarrow N_2 (g) + 4H_2 O (g) + Cr_2 O_3 \]
This equation is already balanced.
