How many moles of sulfur dioxide (SO2) are required to produce 5.0 moles of sulfur (S) according to the following balanced equation? SO2 + 2H2S - 3S + 2H2O

1.67 moles

Explanation:

From the balanced equation of reaction:

1 mole of sulfur dioxide, SO2, is required to produce 3 moles of sulfur, S.

If 1 mole SO2 = 3 moles S, then, how many moles of SO2 would be required for 5 moles S?

     Moles of SO2 needed = 5 x 1/3

                   = 5/3 or 1.67 moles

Hence, 1.67 moles of SO2 would be required to produce 5.0 moles of S.

c most likely

hop this let me know if it is wrong

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.
