Which of the following choices best classifies the following reaction:Mg(SO3)  MgO+SO2 a. combination b. single replacement c. decomposition d. double replacement  e. redox f.  nonredox         

Balance the equation below by placing the correct coefficients in the blanks. Your response should list the coefficients in order from left to right, separated only by commas; no spaces. If no coefficient belongs in a blank, represent it with a “1”. For example the equation 2 H2O →  2 H2+O2 would be represented as 2,2,1.    ____H2(SO4) +____Cr   →    ____H2  +  ____Cr2(SO4)3
