Question

1)C→CO2→Na2CO3→NaCL2)K→K2O→KOH→K2SO4​

Answer 1

Ответ:

Объяснение:

1.

1) C + O2 = CO2

2) 2NaOH + CO2 = Na2CO3 + H2O

3) Na2CO3 + 2HCl = 2NaCl + CO2 + H2O

2.

1) 4K + O2 = 2K2O

2) K2O + H2O = 2KOH

3) 2KOH + H2SO4 = K2SO4 + 2H2O

Answer 2

The two chemical reactions you've provided involve the transformation of elements and compounds. Here's a breakdown of each reaction:

1. C → CO2 → Na2CO3 → NaCl

This reaction involves the conversion of carbon (C) into sodium chloride (NaCl) through several intermediate steps.

• First, carbon (C) is converted to carbon dioxide (CO2) through combustion or other processes.
• Carbon dioxide (CO2) can then be combined with sodium (Na) and other elements to form sodium carbonate (Na2CO3).
• Finally, sodium carbonate (Na2CO3) can react with hydrochloric acid (HCl) to form sodium chloride (NaCl), also known as table salt.

2. K → K2O → KOH → K2SO4

This reaction involves the transformation of potassium (K) into potassium sulfate (K2SO4) through a series of steps:

• Potassium (K) reacts with oxygen (O2) to form potassium oxide (K2O).
• Potassium oxide (K2O) can then react with water (H2O) to form potassium hydroxide (KOH), which is a strong base.
• Finally, potassium hydroxide (KOH) can react with sulfuric acid (H2SO4) to produce potassium sulfate (K2SO4).

These reactions represent a series of chemical transformations that are commonly encountered in chemistry. They are not balanced equations, and the specific conditions and reactants required for these reactions can vary depending on the context in which they occur.
