Chemistry
DrBob222 you have no clue how much you taught me in one day. Thank You so so much for this help of yours. How can I ever thank you.

Chemistry
E) H2SO4 + NaOH = H2SO4+ 2NaOH --> 2H2O + Na2SO4 About the last 2 in Na2SO4, It should be a coefficient right? Not a subscript. Reactants: Sulphic acid, sodium hydroxide Products: Sodium sulphate, water

Chemistry
C) H3PO3 + Ca(OH)2 = H3PO3 + 3CaOH2 Reactants: Phosphic acid, Calcium hydroxide Products: Calcium phosphate, water Could you provide me an example of what you mean by that rule. I sort of understand, but an example would be better.

Chemistry
Complete and balance the following neutralization reactions. then, write the names of all the reactants and all the products in each chemical reaction. A) HNO3 + Al(OH)3 = 3HNO3 + Al(OH)3 -> Al(NO3)3 + 3H2O Reactants: Nitric acid, Aluminum hydroxide Products: Aluminum nitra...

Thanx DrBob222
Thank you sir for helping me out with those chemistry problems.

Chemistry
Balance each of the following skeleton equations. This is the last one left to balance. D) C4H10 + O2 -> CO2 + H2O = C4H10 + O2 -> 4CO2 + 10H

Chemistry
Balance each of the following skeleton equations. C) C3H8 + O2 -> CO2 + H2O This one was a bit harder for me to balance out, but this is what I managed to do. C3H8 + O2 -> 3CO2 + 8H

Chemistry
I was getting restless to post these questions, so I decided to go ahead and post them. Balance each of the following skeleton equations. B) Na + F2 -> NaF I balanced out this equation like this. Na + F2 -> Na2F OR would I write it as -> Na + F2 -> NaF2 , would the...

Chemistry
Balance each of the following skeleton equations. A) KCl + Pb(NO3)2 -> PbCl2 + KNO3 I balanced it out like this. KCl2 + Pb(NO3)2 -> PbCl2 + 2KNO3 After knowing if I've done this correctly, I'll post on my other questions.

Chemistry
Thank you very much sir
