Question

Помогите Al+HCl= Fe+HCl= Cu+HCl= CuSO4+Fe= FeSO4+Cu= Na+H2O=

Answer 1

1) 2Al + 6HCl= 2AlCl3 + 3H2
2) Fe+ 2HCl= FeCl2 + H2
3) Cu+2HCl= CuCl2 + H2
4) CuSO4+ Fe= FeSO4+Cu
5) - реакция не пойдёт, тк медь менее активна чем железо, и поэтому вытеснять Fe не будет
6) 2Na + 2H2O = 2NaOH + H2

Answer 2

Chemical Reactions:

The chemical reactions you provided are as follows:

1. Al + HCl = ? 2. Fe + HCl = ? 3. Cu + HCl = ? 4. CuSO4 + Fe = ? 5. FeSO4 + Cu = ? 6. Na + H2O = ?

Let's go through each reaction and determine the products.

1. Al + HCl = ? - The reaction between aluminum (Al) and hydrochloric acid (HCl) produces aluminum chloride (AlCl3) and hydrogen gas (H2).

2. Fe + HCl = ? - The reaction between iron (Fe) and hydrochloric acid (HCl) produces iron chloride (FeCl2) and hydrogen gas (H2).

3. Cu + HCl = ? - The reaction between copper (Cu) and hydrochloric acid (HCl) produces copper chloride (CuCl2) and hydrogen gas (H2).

4. CuSO4 + Fe = ? - The reaction between copper sulfate (CuSO4) and iron (Fe) results in the displacement of iron by copper, forming copper (Cu) and iron sulfate (FeSO4).

5. FeSO4 + Cu = ? - The reaction between iron sulfate (FeSO4) and copper (Cu) results in the displacement of copper by iron, forming iron (Fe) and copper sulfate (CuSO4).

6. Na + H2O = ? - The reaction between sodium (Na) and water (H2O) produces sodium hydroxide (NaOH) and hydrogen gas (H2).

Please note that these reactions are simplified representations, and the actual reactions may involve more complex chemical species or conditions.
