1. Write the balanced chemical equation for the single displacement reaction of magnesium and sodium thiosulfate.

Is this right?

6Mg + (S*2*O*3)*2 -> 6MgO + 2S*2

2. Write the balanced chemical equation for the double displacement reaction of hydrogen sulphide and potassium hydroxide.

I didn't get this one.

Please help. Thanks.
