Question

K2 + SO3 = ... K2O + H2O=... KOH + SO3=...

Answer 1

K2+2SO3=2KSO3; K2O+H2O=2KOH; 2KOH+SO3=K2SO4+H2O

Answer 2

Let's balance the chemical equations for the reactions you've provided:

1. K2 + SO3 → K2O + ? This equation is not balanced. To balance it, we need to make sure that we have the same number of atoms of each element on both sides of the equation. Here's the balanced equation:

   2K2 + 3SO3 → 3K2O + 3SO2

2. K2O + H2O → ? This equation is not balanced either. To balance it, we need to ensure that we have the same number of atoms of each element on both sides. Here's the balanced equation:

   K2O + H2O → 2KOH

3. KOH + SO3 → ? This equation is also not balanced. To balance it, we need to make sure that we have the same number of atoms of each element on both sides. Here's the balanced equation:

   2KOH + SO3 → K2SO4 + H2O

So, the balanced chemical equations for the given reactions are:

1. 2K2 + 3SO3 → 3K2O + 3SO2
2. K2O + H2O → 2KOH
3. 2KOH + SO3 → K2SO4 + H2O
