Question

Осуществите превращения 1)Mg-MgCl2-Mg(OH)2-MgO 2)S-SO2-SO3-H2SO4_K2SO4-K2O

Answer 1

Ответ:

Объяснение:

1) Mg + 2HCl = MgCl2 + H2

MgCl2 + 2NaOH = Mg(OH)2 + 2NaCl

Mg(OH)2 -> MgO + H2O

2) S + O2 = SO2

2SO2 + O2 = 2SO3

SO3 + H2O= H2SO4

H2SO4+ 2KOH = K2SO4 + 2H2O

K2SO4  -> K2O + SO3

Answer 2

Transformation 1: Mg-MgCl2-Mg(OH)2-MgO

The transformation you provided involves the chemical reactions of magnesium (Mg) with various compounds. Let's break down the steps:

1. Mg reacts with chlorine gas (Cl2) to form magnesium chloride (MgCl2): - Equation: Mg + Cl2 → MgCl2 [[8]](https://www.aversev.by/media/download/files/uchebniki.by/Himiya_Shimanovich_9kl_rus_2019.pdf)

2. Magnesium chloride (MgCl2) reacts with water (H2O) to form magnesium hydroxide (Mg(OH)2): - Equation: MgCl2 + 2H2O → Mg(OH)2 + 2HCl [[2]](https://elib.gsmu.by/bitstream/handle/GomSMU/2694/%D0%A5%D0%B8%D0%BC%D0%B8%D1%8F.pdf?sequence=1&isAllowed=y)

3. Magnesium hydroxide (Mg(OH)2) can further react with heat to form magnesium oxide (MgO): - Equation: Mg(OH)2 → MgO + H2O

So, the complete transformation is: Mg → MgCl2 → Mg(OH)2 → MgO

Transformation 2: S-SO2-SO3-H2SO4-K2SO4-K2O

The transformation you provided involves the chemical reactions of sulfur (S) with various compounds. Let's break down the steps:

1. Sulfur (S) reacts with oxygen (O2) to form sulfur dioxide (SO2): - Equation: S + O2 → SO2 2. Sulfur dioxide (SO2) can further react with oxygen (O2) to form sulfur trioxide (SO3): - Equation: 2SO2 + O2 → 2SO3 3. Sulfur trioxide (SO3) reacts with water (H2O) to form sulfuric acid (H2SO4): - Equation: SO3 + H2O → H2SO4 4. Sulfuric acid (H2SO4) can react with potassium hydroxide (KOH) to form potassium sulfate (K2SO4): - Equation: H2SO4 + 2KOH → K2SO4 + 2H2O 5. Potassium sulfate (K2SO4) can further react with heat to form potassium oxide (K2O): - Equation: K2SO4 → K2O + SO3

So, the complete transformation is: S → SO2 → SO3 → H2SO4 → K2SO4 → K2O

Please note that these transformations are based on the given reactions and may not represent the complete picture of the chemical reactions involving these elements and compounds.
