Question

Make a balance Fe(OH)3=Fe2O3 + H2OK2S + Cl2= KCl + SFe2O3 + C= Fe + CO2​

Answer 1

Ответ:

2 Fe(OH)3 = Fe2O3 + 3 H2O

K2S + Cl2 = 2 KCl + S

2 Fe2O3 + 3 C = 4 Fe + 3 CO2

Answer 2

Ответ:

Объяснение:

Fe(OH)3 -> Fe2O3 + H2O   (эта реакция не ОВР)

Fe(+3)O(-2)H(+) -> Fe(+3)O(-2) + H(+)O(-2)

K2S + Cl2 = 2KCl + S

S(-2) -2e = S(0)          1    ок-ие

в-ль

Cl2(0) +2e = 2Cl(-)    1    в-ие

ок-ль

2Fe2O3 + 3C =4 Fe + 3CO2

Fe(+3) +3e = Fe(0)     4    в-ие

Answer 3

It looks like you've provided a set of chemical equations. To balance these equations, we need to ensure that the same number of each type of atom is present on both sides of the equation. Let's start by balancing the equations one by one:

1. Fe(OH)3 = Fe2O3 + H2O

   There's an imbalance in the number of oxygen atoms. To balance it, we can add a coefficient of 3 in front of H2O on the right side:

   Fe(OH)3 = Fe2O3 + 3H2O

2. K2S + Cl2 = KCl + S

   Both potassium (K) and sulfur (S) are balanced. However, the chlorine (Cl) atoms are not balanced. We can balance them by placing a coefficient of 2 in front of KCl on the right side:

   K2S + Cl2 = 2KCl + S

3. Fe2O3 + C = Fe + CO2

   The number of iron (Fe) atoms is balanced, but the carbon (C) and oxygen (O) atoms are not. To balance them, we need to place a coefficient of 3 in front of CO2 on the right side:

   Fe2O3 + 3C = 2Fe + 3CO2

So, the balanced equations are:

1. Fe(OH)3 = Fe2O3 + 3H2O
2. K2S + Cl2 = 2KCl + S
3. Fe2O3 + 3C = 2Fe + 3CO2

Please double-check the coefficients to ensure accuracy.
