The ratio of the concentration of potassium ions (K⁺) to the concentration of carbonate ions (CO₃²⁻) = 2: 1
<h3>Further explanation</h3>Stochiometry in Chemistry studies about chemical reactions mainly emphasizes quantitative, such as the calculation of volume, mass, amount, which is related to the number of actions, molecules, elements, etc.
Reaction equations are chemical formulations for reagents and product substances
Reaction coefficients are numbers in the chemical formula of substances involved in the reaction equation. Reaction coefficients are useful for balancing reagents and products.
The reaction coefficient shows the ratio of the number of moles or molecules of the reacting substance
The ionization reaction is the reaction of the decomposition of a substance into its ions when the substance is dissolved in water.
- Molarity (M)
Molarity shows the number of moles of solute in every 1 liter of solution.
Electrolytes will dissociate into ions when dissolved in water
While non-electrolyte solutions do not produce ions
Electrolyte solutions can be
- 1. Electrolytes are strong if in a solution can be fully ionized usually expressed by the degree of ionization α = 1
- 2. Electrolytes are weak if in ions the solution is only partially ionized. The degree of ionization ranges from 0 <α <1
Potassium carbonate (K₂CO₃) will dissociate into ions
K₂CO₃ ⇒ 2K⁺+ CO₃²⁻
Comparison of reaction coefficients = mole ratio = concentration ratio for the same volume, so
The mole ratio of the ions is
K⁺ : CO₃²⁻ = 2: 1
This comparison also shows the ratio of concentrations of ions: (K₂CO₃ concentration = 0.015 M)
K⁺: CO₃²⁻ = 2.0.015: 1.0.015
K⁺: CO₃²⁻ = 0.03: 0.015 = 2: 1

Answer:
Compound 1. Sulfur Dioxide
Compound 3. Dichloromethane
Compound 4. Phosphorus Trichloride
<em>(figure attached)</em>
Explanation:
Compound 1. Sulfur Dioxide
Polar compound
Through the Lewis structure it is confirmed that SO₂ is a polar compound, because it is an asymmetric compound having two regions of different polarity. The lower region having oxygen groups is more electronegative then the upper region.
Compound 2. Carbon Dioxide
Non polar Compound
Through the Lewis structure it is confirmed that CO₂ is a non polar compound, because it is a symmetric compound having two regions of same polarity. The left region and the right region both contains oxygen groups having same electronegativity.
Compound 3. Dichloromethane
Polar compound
Through the Lewis structure it is confirmed that CH₂Cl₂ is a polar compound, because it is an asymmetric compound having two regions of different polarity. Two chlorine atoms are attached to it and as we know that chlorine is a more electronegative element than hydrogen so it attracts the bonding pair of electrons towards itself which creates polarity.
Compound 4. Phosphorus Trichloride
Through the Lewis structure it is confirmed that PCl₃ is a polar compound, because three chlorine atoms attached to it and as we know that chlorine is a more electronegative element so it attracts the bonding pair of electrons towards itself which creates polarity.
