charge of elements increases by one as you move from left to right.
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.
Answer:
86.85°C
Explanation:
K = °C + 273.15
360K − 273.15 = 86.85°C ≈ 87°C
The compound potassium carbonate(K₂CO₃) is soluble in the water. The formulas for the ions that interact with the water is K⁺ and (CO₃)²⁻.
Dissociation of any compound is defined as the breaking of a compound into a simpler substance which is capable of recombining under different conditions. The compound potassium carbonate(K₂CO₃) is an ionic compound, and ionic compound is formed by a combination of cation and anion. When ionic compounds are dissolved in the water, it separates into the cations and anions.
Potassium carbonate(K₂CO₃) is a strong electrolyte. It means that it is completely dissociate in the water. Its dissociation in the water is shown as
K₂CO₃(aq)→2K⁺(aq)+(CO₃)²⁻(aq)
Therefore, the compound potassium carbonate forms K⁺ and (CO₃)²⁻ ions when interact with the water.
