Question

Допишіть рівняння хімічних реакцій K=H20= K2O+H2O= K+CE2= H2+F2=

Answer 1

2K + 2H2O = 2KOH + H2
K2O + H2O = 2KOH
2K + Cl2 = 2KCl
H2 + F2 = 2HF

Answer 2

Chemical Equations:

1. Potassium (K) reacts with water (H2O) to form potassium hydroxide (KOH) and hydrogen gas (H2): - Equation: 2K + 2H2O → 2KOH + H2 [[1]]

2. Potassium oxide (K2O) reacts with water (H2O) to form potassium hydroxide (KOH): - Equation: K2O + H2O → 2KOH [[2]]

3. Potassium (K) reacts with carbon disulfide (CS2) to form potassium sulfide (K2S) and carbon (C): - Equation: 2K + CS2 → K2S + C [[3]]

4. Hydrogen gas (H2) reacts with fluorine gas (F2) to form hydrogen fluoride (HF): - Equation: H2 + F2 → 2HF [[4]]

Please note that these equations are balanced and represent the stoichiometry of the reactions.
