Question

What is the total masses of the reactants for the equation: `2SeO_2 (g) + O_2->2SeO_3 (g)`?

Answer 1

`2SeO_2(g) + O_2(g) rarr 2SeO_3(g)`

Explanation:

The equivalent mass of `SeO_2` is `126.96` `g*mol^-1`. Dioxygen gas has an equivalent mass of `32.00` `g*mol^-1`. So the reactant mass is `126.96*gxx2+32.00*g` `=` `??g`.

What mass of `SeO_3(g)` results?
