Answer 2

I apologize, but the chemical formula you provided, "M(K2CO7)M(KMnO4)M(Al2(SO4)3)," does not represent any known chemical compound. It seems like "M" is used as a placeholder or variable, but without specific values for "M" or proper chemical symbols, the formula cannot be identified.

If you have the correct chemical formulas for the compounds you're looking for, please provide them, and I'll be happy to help you with any information you need.
