Draft 1

The image you sent me contains a chemical equation written in Russian. The equation is:

CaCl2 + 2KOH = Ca(OH)2 + KCl

This is a balanced chemical equation for a double displacement reaction between calcium chloride (CaCl2) and potassium hydroxide (KOH) to produce calcium hydroxide (Ca(OH)2) and potassium chloride (KCl).

Here's a breakdown of the reaction:

Reactants:

Calcium chloride (CaCl2) - ionic compound, dissociates in water to form Ca2+ and 2Cl- ions.

Potassium hydroxide (KOH) - ionic compound, dissociates in water to form K+ and OH- ions.

Products:

Calcium hydroxide (Ca(OH)2) - ionic compound, slightly soluble in water.

Potassium chloride (KCl) - ionic compound, very soluble in water.

The net ionic equation for this reaction would focus only on the ions that are changing hands. In this case, the net ionic equation would be:

Ca2+ (aq) + 2OH- (aq) -> Ca(OH)2(s)

Let me know if you have any other questions about the chemical equation or the reaction itself.

Draft 2

The image you sent me contains a chemical equation written in Russian. The equation is:

CaCl2 + 2KOH = Ca(OH)2 + KCl

This is a balanced chemical equation for a double displacement reaction between calcium chloride (CaCl2) and potassium hydroxide (KOH) to produce calcium hydroxide (Ca(OH)2) and potassium chloride (KCl).

Let's break down the reaction:

Reactants:

Calcium chloride (CaCl2) - ionic compound, source of calcium (Ca2+) and chloride (Cl-) ions

Potassium hydroxide (KOH) - ionic compound, source of potassium (K+) and hydroxide (OH-) ions

Products:

Calcium hydroxide (Ca(OH)2) - ionic compound, slightly soluble in water

Potassium chloride (KCl) - ionic compound, very soluble in water

The reaction can be summarized as the following:

Ca2+ (aq) + 2Cl- (aq) + 2K+ (aq) + 2OH- (aq) -> Ca(OH)2 (s) + 2K+ (aq) + 2Cl- (aq)

Notice how the potassium (K+) and chloride (Cl-) ions appear on both sides of the equation. These are called spectator ions and do not participate in the actual chemical change. We can cancel them out to get the net ionic equation:

Ca2+ (aq) + 2OH- (aq) -> Ca(OH)2 (s)

This net ionic equation highlights the essential parts of the reaction: the combination of calcium and hydroxide ions to form calcium hydroxide.

The image you sent me contains a chemical equation written in Cyrillic script. The equation is:

CaCl2 + 2KOH = Ca(OH)2 + KCl

This is a balanced chemical equation for a double displacement reaction between calcium chloride (CaCl2) and potassium hydroxide (KOH) to produce calcium hydroxide (Ca(OH)2) and potassium chloride (KCl).

Let's break down the reaction:

Reactants:

Calcium chloride (CaCl2) - ionic compound, source of calcium (Ca2+) and chloride (Cl-) ions

Potassium hydroxide (KOH) - ionic compound, source of potassium (K+) and hydroxide (OH-) ions

Products:

Calcium hydroxide (Ca(OH)2) - ionic compound, slightly soluble in water

Potassium chloride (KCl) - ionic compound, very soluble in water

The reaction can be summarized as the following:

Ca2+ (aq) + 2Cl- (aq) + 2K+ (aq) + 2OH- (aq) → Ca(OH)2 (s) + 2K+ (aq) + 2Cl- (aq)

Since potassium and chloride ions appear on both sides of the reaction, they are considered spectator ions and can be canceled out to write the net ionic equation:

Ca2+ (aq) + 2OH- (aq) → Ca(OH)2 (s)
