Question

KCL + .... -> KNO3 + .... Fe(NO3)3 + ... -> Ba(No3)2 K2SO4 + ... -> BaSO4 | + ....

Answer 1

Ответ:

1. KCl+HNO3= KNO3+HCl

2. 2Fe(NO3)3+3Ba(OH)2= 3Ba(NO3)2+2Fe(OH)3

3. K2SO4+Ba(OH)2= BaSO4+2KOH

Answer 2

It appears that you're providing chemical reactions with some missing reactants and products. I'll do my best to complete the reactions for you.

1. KCl + AgNO3 -> AgCl + KNO3 This reaction is a double displacement reaction that forms a precipitate (AgCl).

2. Fe(NO3)3 + 3NaOH -> Fe(OH)3 + 3NaNO3 This is a double displacement reaction between iron(III) nitrate and sodium hydroxide, forming iron(III) hydroxide (Fe(OH)3) as a precipitate.

3. K2SO4 + Ba(NO3)2 -> BaSO4 + 2KNO3 This is a double displacement reaction that forms barium sulfate (BaSO4) as a precipitate.

If you have more specific reactants or products in mind for the reactions, please provide them, and I can help you balance the equations accordingly.
