Answer 1

Ответ:

4Na+O2=2Na2O

Na2O+H2O=2NaOH

3NaOH+H3PO4=Na3PO4+3H2O

2Mg+O2=2MgO

MgO+H2O=Mg(OH)2

Answer 2

Chemical Transformations

To perform the transformations provided, we'll need to consider the reactions involved in each step.

1. Na to Na2O to NaOH to Na3PO4: - Sodium (Na) reacts with oxygen (O2) to form sodium oxide (Na2O). - Sodium oxide (Na2O) reacts with water (H2O) to form sodium hydroxide (NaOH). - Sodium hydroxide (NaOH) reacts with phosphoric acid (H3PO4) to form sodium phosphate (Na3PO4).

2. Mg to MgO to Mg(OH)2 to Mg(OH)3: - Magnesium (Mg) reacts with oxygen (O2) to form magnesium oxide (MgO). - Magnesium oxide (MgO) reacts with water (H2O) to form magnesium hydroxide (Mg(OH)2). - Magnesium hydroxide (Mg(OH)2) can further react with water to form magnesium hydroxide dihydrate (Mg(OH)3)2.

Let's take a look at the specific reactions involved in each step.

Chemical Reactions

1. Na to Na2O: - The reaction between sodium and oxygen to form sodium oxide is represented as: ``` 4 Na + O2 -> 2 Na2O ```
