2K + 2H2O → 2KOH + H2

This reaction shows which detail about potassium and hydrogen?
Hydrogen is more reactive than potassium.
Potassium and hydrogen form ionic bonds.
Potassium is more reactive than hydrogen.
Potassium and hydrogen form covalent bonds

Answer 1

A

Step-by-step explanation:

Hydrogen is more reactive than potassium.

Answer 2

2K + 2H2O → 2KOH + H2

So Hydrogen is more reactive than pottasium .

• According to law of conservation of matter, 2 moles of potassium react with water to produce 1 mole of hydrogen gas.

• So, 2 moles of potassium produce 1 mole of hydrogen gas.
