Calculate the mass of chromium produced from 50g of Cr2O3.

34 gram of chromium produced from 50g of

Explanation:

To calculate the moles :

The decomposition of follows the equation :

According to stoichiometry :

2 moles of produce = 4 moles of

Thus 0.33 moles of will produce=  of

Mass of

Thus 34 gram of chromium produced from 50g of

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

it would be a gas formation
