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
