Question

I have these 5 chemical equations and I keep getting the same 1:1 ratio on all of them. I must be doing something wrong!

KCL + NaNO3 = KNO3 + NaCl
HNO3 + KOH = H2O + KNO3
H2O + SO3 = H2SO4
4Na + O2 = 2Na2O
2NO2 = 2NO + O2

Answer 1

I suspect you have posted the same questions under other names. That makes it difficult for us to follow. However, when you say ratio you don't tell us what kind of ratio it is.
For the first one
1:1:1:1 is correct.
1:1:1:1 is correct for #2.
4:1:2 is correct for #3. If you are interest JUST IN Na to Na2O, then 4:2 (or 2:1 in the reduced form) is all you need. If interest in Na to O2, then 4:1 is correct.
2:2:1 is the last one.
If there is another interpretation, please let me know and I can be more detailed.
