Question

Нужна помощь в Химии заранее спасибо! NaOH + H₂ SO₄ → Fe Cl₃ + KOH → Нужно решить, а я не понимаю

Answer 1

1) 2NaOH + H2SO4 → Na2SO4 + 2H2O
Это реакция нейтрализации: основание + кислота → соль + вода.

2) FeCl3 + 3KOH → Fe(OH)3↓ + 3KCl
Это реакция обмена.

Answer 2

Balancing Chemical Equations

To balance the chemical equations you provided, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Let's go through each equation step by step:

1. NaOH + H₂SO₄ → FeCl₃ + KOH

To balance this equation, we need to make sure that the number of atoms of each element is the same on both sides. Let's start with the elements that appear in only one compound on each side of the equation:

- Sodium (Na): There is one Na atom on the left side and none on the right side. To balance this, we can place a coefficient of 3 in front of NaOH on the left side: 3NaOH.

- Hydrogen (H): There are two H atoms on the left side and two H atoms on the right side. Hydrogen is already balanced.

- Sulfur (S): There is one S atom on the right side and none on the left side. To balance this, we can place a coefficient of 3 in front of H₂SO₄ on the left side: 3H₂SO₄.

- Oxygen (O): There are three O atoms on the left side and three O atoms on the right side. Oxygen is already balanced.

- Iron (Fe): There is one Fe atom on the right side and none on the left side. To balance this, we can place a coefficient of 3 in front of FeCl₃ on the right side: 3FeCl₃.

- Potassium (K): There is one K atom on the right side and none on the left side. To balance this, we can place a coefficient of 3 in front of KOH on the right side: 3KOH.

After balancing all the elements, the balanced equation is:

3NaOH + 3H₂SO₄ → 3FeCl₃ + 3KOH

Please note that the coefficients in front of the compounds represent the number of molecules or formula units, not individual atoms.

I hope this helps! Let me know if you have any further questions.
