PLEASE,COULD ANYONE HELP ME to balance this redox reaction : Cr2S3 PbO2 + H2SO4 + -------> PbSO4 H2Cr2O7+H20

Answer 1

I REALLY wish you would spell chemistry right. You've posted the last several days with the wrong spelling.

Answer 2

I've done all but the water. You can fill that in.
2Cr2S3 + 30PbO2 + 24H2SO4 --> 30PbSO4 + 2H2Cr2O7 + ?H20

Check it out. Make sure I made no typos.

Answer 3

please,sir,If you give me the answers briefly means with oxidation state and half reaction,I will be grateful to you.Because i am suffering so much to find out oxidation state of Cr2S3 and half reaction.
