A volume of 25cm3 of a carbonate solution of concentration 0.2mol dm-3 was neutralized by 20 cm3 of acid of concentration 0.5 mol dm-3. The mole ratio in which the reactants combine is? 1 mol of carbonate to 1 mol of acid

1 mol of carbonate to 2 mol of acid

2 mol carbonate to 1 mol of acid

3 mol of carbonate to 1 mol of acid

1 mol of carbonate to 2 mol of acid

Explanation:

To calculate the number of moles for given molarity, we use the equation:

a)

b)

Thus the mole ratio of carbonate to acid is =

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
