s = -2 -4r
-2=4r+s s=-4r-2 or s=-(4r+2)
Solving for two unknown variables (s and t) requires two independent equations. You have only one.
s = -70
v
2h2s + so2 ----------> 3s + 2h2o
It is the same as: 2s = t
s = 20
No they are not the products.Product is as this. H2SO3
46
No.
It is an equation in the single variable, s.
