Question

помогите плиз решить цепочку (mgoh)2so4 - mgso4 - mgcl - mg

Answer 1

(MgOH)2SO4 +H2SO4 = 2MgSO4 + 2H2O

MgSO4 + BaCl2 = MgCl2 +BaSO4

MgCl2 = Mg + Cl2 (электролиз расплава)

Answer 2

1. (MgOH)2SO4 - This compound is magnesium hydroxide sulfate. To understand the chemical formula, we can break it down into its components. Mg is the symbol for magnesium, OH is the hydroxide ion, and SO4 is the sulfate ion. Therefore, the compound is made up of two magnesium ions, two hydroxide ions, and one sulfate ion.

2. MgSO4 - This compound is magnesium sulfate. It is composed of one magnesium ion and one sulfate ion.

3. MgCl - This compound is magnesium chloride. It is composed of one magnesium ion and one chloride ion.

4. Mg - This is simply magnesium metal, which consists of one magnesium ion.

In terms of the chemical reactions, we can see that:

1. (MgOH)2SO4 can be broken down into MgSO4 and H2O (water) when it reacts with an acid. This is a neutralization reaction.

2. MgSO4 can be further broken down into MgCl and Na2SO4 when it reacts with sodium chloride (NaCl) in a double displacement reaction.

So, the overall reaction would be:

(MgOH)2SO4 + 2HCl → 2MgCl + 2H2O MgSO4 + 2NaCl → MgCl + Na2SO4

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