Question

KOH-K-KCI-KNO3-KNO2​

Answer 1

Ответ:

Объяснение:

4KOH = 4K + O2 + 2H2O

2K + 2HCl =2 KCl + H2

KCl + AgNO3 = AgCl + KNO3

2KNO3 -> 2KNO2 + O2

Answer 2

The given sequence KOH-K-KCl-KNO3-KNO2 represents a series of chemical compounds and their respective chemical formulas. Let's break it down:

1. KOH: This represents potassium hydroxide, which has the chemical formula KOH.

2. K: This symbolizes potassium, an alkali metal element on the periodic table.

3. KCl: This stands for potassium chloride, which has the chemical formula KCl. It is an ionic compound composed of one potassium ion (K+) and one chloride ion (Cl-).

4. KNO3: This denotes potassium nitrate, with the chemical formula KNO3. It is an ionic compound consisting of one potassium ion (K+) and one nitrate ion (NO3-).

5. KNO2: This represents potassium nitrite, having the chemical formula KNO2. It is also an ionic compound composed of one potassium ion (K+) and one nitrite ion (NO2-).

Each compound in the sequence is connected by dashes (-), indicating that they are related in some way. It seems to follow a pattern where potassium (K) is combined with different anions (negatively charged ions) to form various compounds.
