Question

The compound sb4o5cl2(s), which has been investigated because of its interesting electrical properties, can be prepared by warming a mixture of antimony(iii) oxide and antimony(iii) chloride, both of which are solids. what is the coefficient of antimony(iii) oxide in the balanced equation for the reaction? (balance the equation with the smallest possible whole number coefficients.)

Answer 1

Sb2O3 + SbCl3 = Sb4O5Cl2 To balance Cl each side from Cl3 and Cl2 .. need 6 Cl Sb2O3 + 2SbCl3 = 3Sb4O5Cl2 now to balance O.... O3 and O5 ... so need 15O 5Sb2O3 + 2SbCl3 = 3Sb4O5Cl2 Now check Sb each side 10 + 2 = 3x4 = 12 so OK

Answer 2

The stoichiometric coefficient of the antimony(III) oxide is 5.

Step-by-step explanation:

The compound
`Sb_4O_5Cl_2` is prepared by heating the antimony(III) oxide with antimony(III) chloride.

The balanced chemical reaction is given by:

`5Sb_2O_3+2SbCl_3\rightarrow 3Sb_4O_5Cl_2`

The stoichiometric coefficient of the antimony(III) oxide is 5.
