Answer:
[H⁺] = 0.00013 M
[OH⁻] = 7.7 × 10⁻¹¹ M
Explanation:
Step 1: Calculate the concentration of H⁺ ions
HCl is a strong acid that dissociates according to the following equation.
HCl ⇒ H⁺ + Cl⁻
The molar ratio of HCl to H⁺ is 1:1. The concentration of H⁺ is 1/1 × 0.00013 M = 0.00013 M.
Step 2: Calculate the concentration of OH⁻ ions
We will use the ionic product of water equation.
Kw = 10⁻¹⁴ = [H⁺] × [OH⁻]
[OH⁻] = 10⁻¹⁴/[H⁺] = 10⁻¹⁴/0.00013 = 7.7 × 10⁻¹¹ M
Salt crystals are shaped like cubes. Salt is part of the isometric crystal system.
Answer:
- The name for the potassium oxide's structure is ionic.
Properties:
- High melting point.
- Soluble in water.
Explanation:
- The ionic structure it is formed by a cation (atom with positive charge) and an anion (atom with negative charge). In this case, potassium is the cation and the oxigen is the anion.
- Since potassium oxide is an ionic compound, it has a high melting point, because of the strong bonds. Also, it is soluble in polar solvents, like water, because its ions generate polarity in the molecule.
Answer:
1) The reaction rate is double with respect to that reactant
Explanation:
Hello,
By considering the rate law:
If we double the reactant A concentration, by definition, the rate will be doubled as well since the 
power is one (order 1), this could be proved just by checking it out in the rate law.
Best regards.
