Question

K => K2O => KOH => KCl Решить:​

Answer 1

Ответ:

K => K2O => KOH => KCl

1) K + O2 => K2O(соед.) (оксид калия)

2) K2O + H2O => 2KOH(соед.) (гидрооксид калия)

3) KOH + HCl => KCl + H2O (обмен.) (хлорид калия)

4) 2K + H2SiO3 => K2SiO3 + H2 (замещ.) (силикат калия)

Answer 2

Chemical Equation:

The given chemical equation is: K + K2O -> KOH + KCl.

Balancing the Equation:

To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

The balanced equation is: 2K + K2O -> 2KOH + KCl.

Explanation:

In the given chemical equation, potassium (K) reacts with potassium oxide (K2O) to produce potassium hydroxide (KOH) and potassium chloride (KCl).

The balanced equation shows that 2 atoms of potassium (K) react with 1 molecule of potassium oxide (K2O) to produce 2 molecules of potassium hydroxide (KOH) and 1 molecule of potassium chloride (KCl).

Therefore, the balanced equation is: 2K + K2O -> 2KOH + KCl.
