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

I read it and responded. It takes time to think these things through and write them down, especially when we are trying to type in subscripts and superscripts.

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

Hello Dr Bob222

I really appreciate for your caring to all chemistry questions.
I need your help Sir.
How many grams of CO2 are needed to neutralize a 5 L tank of water with a pH of 11.5? (H2O + CO2-> H2CO3)

my answer is around 0.22 grams of CO2.
is that true or not?

Best Regards

I apologize if I missed your previous post. Can you please reiterate your question or provide more details about the balancing problem you are facing? I'll do my best to assist you.
