Question

SO3+H2O= K+H2O= H2O= BaSO4+HNO3= CuCO3+HCI=

Answer 1

SO3+H2O=
K+H2O=K(OH)2
2H20=H2 + 2O2
BaSO4 + HNO3= H2SO4 + Ba(NO3)2

Answer 2

Let's go through each of the chemical equations you provided and balance them:

1. SO3 + H2O -> H2SO4

To balance this equation, you need to ensure that the number of atoms of each element is the same on both sides of the equation. Here's the balanced equation:

SO3 + H2O -> H2SO4

2. K + H2O -> KOH + H2

This equation is already balanced. It represents the reaction of potassium (K) with water (H2O) to form potassium hydroxide (KOH) and hydrogen gas (H2).

3. H2O -> H2O

This equation represents the phase change of water from one state to another, but it is already balanced since the number of water molecules remains the same.

4. BaSO4 + HNO3 -> Ba(NO3)2 + H2SO4

To balance this equation, you need to make sure that the number of atoms of each element is the same on both sides. Here's the balanced equation:

BaSO4 + 2 HNO3 -> Ba(NO3)2 + H2SO4

5. CuCO3 + 2 HCl -> CuCl2 + CO2 + H2O

To balance this equation, you need to ensure that the number of atoms of each element is the same on both sides. Here's the balanced equation:

CuCO3 + 2 HCl -> CuCl2 + CO2 + H2O

Please note that these balanced equations represent the stoichiometry of the reactions based on the given reactants.
