The metric ton of CO2 product per gallons of gas can be calculated with the following. 8.78 x 10-3 metric tons of CO2 are emitted per gallon of gas. Let say the gallon of gas is 1288. Would the CO2 produced be around 11.3 tons? Thanks

Let say you were given this equation: NiBr2 + Co = Ni + CoBr2 How can you tell which is liquid,gas,solid,aqueous? Do you just use what you know and figure it out? Like since NiBr2 can be broken down because of the solubility rule, you can assume it aq then Co is a metal so you...

The world equation didn't have any sulfate on the product side :(. I'm guessing such formula can't be right since how can there be sulfate on one side and there none on the other. So the words equation is wrong right? Thanks

Chemistry
I need to write the total ionic equation for this equation. Copper(ii)sulfate + iron = iron(iii)+ copper. Won't it be Cu2+ + SO4-2 + Fe = Fe3+ + Cu ? The answer key say 3Cu2+ + 3SO4-2 + 2Fe = 2Fe3+ + 3SO4-2 + 3Cu Where did they get the sulfate for the product from? Didn...

Oh, thanks you for that! If it was H2O2 + O2 + Heat = H2O + O2 it would still be decomposition?

Chemistry
DrBob, could you clarify what you mean by " one compound on the left forms more than one on the right" Thanks.

Chemistry
H2O2 + Heat = H2O + O2 Would this be combustion or decomposition? Since the products are H2O and O2, I thought it would be combustion but then H2O can be decompose into H2O and O2 which would be decomposition.

Science
Could anyone link or tell me why does oxygen ignite at high temperature? Thanks

A skeleton equation is not a balanced equation.- Is this sometime true, never true or always true? Can't there be some skeleton equation that is already balanced, thus it sometime true? Thanks

Chemistry
I mean OH sorry. So this isn't one of the 6 type of reactions? Thanks
