Question

MgMgo MgCl2 Mg(OH)2P-P2O5 H3PO4 Ca3(PO4)2​

Answer 1

Ответ:

Объяснение:

2Mg + O2 = 2MgO

MgO + 2HCl = MgCl2 + H2O

MgCl2 + 2NaOH = Mg(OH)2↓ + 2NaCl

4P + 5O2 = 2P2O5

P2O5 + 3H2O = 2H3PO4

2H3PO4 + 3CaO = Ca3(PO4)2 + 3H2O

Answer 2

It seems like you've listed a series of chemical compounds. Here's a breakdown of each:

1. MgMg: This looks like a duplication or a typo. It might be Mg, which stands for magnesium.

2. MgCl2: This is magnesium chloride. It's a chemical compound consisting of one magnesium ion and two chloride ions.

3. Mg(OH)2: This is magnesium hydroxide, commonly known as milk of magnesia. It's an antacid and a laxative.

4. P-P2O5: This seems a bit unclear. P could represent phosphorus, and P2O5 is the chemical formula for diphosphorus pentoxide.

5. H3PO4: This is phosphoric acid. It contains three hydrogen ions, one phosphorus ion, and four oxygen ions.

6. Ca3(PO4)2: This is calcium phosphate. It's a compound commonly found in minerals and bones.

If you have any specific questions about these compounds or if there's something else you'd like to know, feel free to ask!
