Question

4. S + O2 —>K + H Cl —>Na2 O + H2O —>химия 8 класс​

Answer 1

Ответ:

Объяснение:

S + O2 = SO2

2K + 2HCl =2 KCl + H2↑

Na2O + H2O = 2NaOH

Answer 2

The chemical equations you've provided seem to be incomplete or not entirely clear. I'll try to interpret what you might be asking, but please provide more details if you have a specific question.

1. S + O2: This equation appears to represent the reaction of sulfur (S) with oxygen (O2) to form sulfur dioxide (SO2):

S + O2 → SO2

2. K + H Cl: It seems like you're indicating the reaction between potassium (K) and hydrochloric acid (HCl) to produce potassium chloride (KCl) and hydrogen gas (H2):

2K + 2HCl → 2KCl + H2

3. Na2 O + H2O: This equation appears to depict the reaction of sodium oxide (Na2O) with water (H2O) to produce sodium hydroxide (NaOH):

Na2O + H2O → 2NaOH

If you have specific questions about these reactions or need more information about chemical reactions in the 8th-grade curriculum, please let me know, and I'll be happy to help.
