These are the other equations I've balanced. I need help with one. AgNO3 + K2Cr2O7 --> double replacement AgNO3 + K2Cr2O7 --> AgCr2O7 + K2NO3 Please tell me if I've balanced these right. Br2 + NiI3 --> single replacement, element is a non-metal Br2 + NiI3 --&g...

Thank you very much DrBob222, if I ever get stuck again, I'll be sure to ask you, but before that I'll try to figure out the problems myself as a challenge. Thank you

DrBob222 I am kind of stuck with the balancing stuff, and I already had send the post, did you not read it?

Also for this equation: BaCl2 + Pb(NO3)2 I know that there is an invisible 1 infront of Ba, and that Cl is 2, but say if there wasn't that 2 there, then would there be an invisible 1 coeffient infront of Cl?

DrBob222 I also want to ask you something which was confusing me like a nightmare all that time, and today I realized it. For ex. C6H12O4 + 7O2 --> 6CO2 + 6H2O This equation here is balanced. But on the right side the coefficients 6 and 6 equal up to 12, isn't the left ...
