Question

Вместо вопросительного знака написать формулу , уровнять реакции, расставив коэффициенты, и определить их тип Fe(OH)3-------> Fe2O3 +?Zn+?----->Cu+ZnCl2?+HCl------>ZnCl2+?

Answer 1

2Fe(OH)3-------> Fe2O3 +3H2O реакция разложения

Zn+CuCl2----->Cu+ZnCl2    реакция замещения

Zn+2HCl------>ZnCl2+H2  реакция замещения

Answer 2

Balanced Reactions:

The balanced reactions for the given equations are as follows:

1. Fe(OH)3 → Fe2O3 + H2O

2. Zn + CuCl2 → Cu + ZnCl2

3. HCl + Zn → ZnCl2 + H2

Explanation:

1. The first equation represents the reaction between iron(III) hydroxide (Fe(OH)3) and water (H2O) to form iron(III) oxide (Fe2O3) and water. To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. The balanced equation is:

Fe(OH)3 → Fe2O3 + H2O

2. The second equation represents the reaction between zinc (Zn) and copper(II) chloride (CuCl2) to form copper (Cu) and zinc chloride (ZnCl2). To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. The balanced equation is:

Zn + CuCl2 → Cu + ZnCl2

3. The third equation represents the reaction between hydrochloric acid (HCl) and zinc (Zn) to form zinc chloride (ZnCl2) and hydrogen gas (H2). To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. The balanced equation is:

HCl + Zn → ZnCl2 + H2

Please note that the question mark (?) in the original equation is not clear. If you provide more information or clarify the missing reactant or product, I can help you balance the equation accordingly.
