one sec

H2SO3+Ca(OH)2=???+H2 2 H 2 1 S 0 3 O 3 1 Ca 0 2 (OH) 0 2 H 2

@jwheele1 what? Sorry, I dont understand

5. jwheele1

well all i did was tell you how many of each element or polyatomic ion were on each side. I can help you balance it but i dont know how to fill in the question mark part =(

6. Mello

oh i see, thanks anyway

H2SO3 is sulfurous acid, Ca(OH)2 is calium hydroxide, a base. A reaction between an acid and base always produces water and some kind of salt. the H+ from the acid and the OH- from the base form water. The other product will be some combination of calcium (+2) and sulfite (-2). Balancing comes after getting the reactants and products correct first.

CaSO4.

9. jwheele1

H2SO3+Ca(OH)2=CaSO4+H2 2 H 2 1 S 1 3 O 4 1 Ca 1 2 (OH) 0 2 H 2

10. jwheele1

Now, you can balance

11. jwheele1

That cant be right becaus there is no OH on the right side....or did you break it up somehow?

12. JFraser

Along with the H+ ion, the hydroxide goes into making water. H_2O and H-OH are the same thing

13. JFraser

CaSO3, not CaSO4. calcium sulfITE is the product, not calcium sulfATE

14. Gochi

sorry .

okey dokey...like i mentioned earlier...I am NO chemist, lol
