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.

1. You have the wrong formula for sodium thiosulfate. It is

Na2S2O3 Try again

2. How about
H2S + 2 KOH -> K2S + 2H2O ?

1. To write the balanced chemical equation for a single displacement reaction, we need to identify the reactants and the products and balance the number of atoms on both sides. In this case, the reactants are magnesium (Mg) and sodium thiosulfate (Na2S2O3), and the products are magnesium oxide (MgO) and sulfur (S).

The balanced chemical equation for this reaction can be written as:

2Mg + Na2S2O3 -> 2MgO + S

In the equation, we balanced the number of magnesium atoms and sulfur atoms on both sides. We also included the correct subscripts for sodium (Na) and oxygen (O) atoms in Na2S2O3 and MgO, respectively.

2. To write the balanced chemical equation for a double displacement reaction, we need to identify the reactants and the products and balance the number of atoms on both sides. In this case, the reactants are hydrogen sulfide (H2S) and potassium hydroxide (KOH), and the products are potassium sulfide (K2S) and water (H2O).

The balanced chemical equation for this reaction can be written as:

H2S + 2KOH -> K2S + 2H2O

In the equation, we balanced the number of hydrogen, sulfur, and oxygen atoms on both sides. We also included the correct subscripts for potassium atoms in K2S and water molecules (H2O).
