Answer:
pH = 11.30
Explanation:
pH is defined as -log [H⁺]
To find [H⁺] from [OH⁻] -Concentration of hydroxide ion-, we must use the equilibrium of water:
H₂O(l) ⇄ H⁺(aq) + OH⁻(aq)
Keq = 1x10⁻¹⁴ = [H⁺] [OH⁻]
[H⁺] = 1x10⁻¹⁴ / [OH⁻]
[H⁺] = 1x10⁻¹⁴ / 2x10⁻³M
[H⁺] = 5x10⁻¹²M
pH = -log (5x10⁻¹²M)
<h3>pH = 11.30</h3>
Answer:
A force involves an interaction between two or more objects, and it causes a push or pull between the objects. ... Good examples of opposing force include drag due to interaction with an air mass and the force due to friction between two objects.

Answer:
Liquid particles are farther apart than solid particles.
Explanation:
Liquid particles are more far apart than solid particles, explaining why it takes the shape of its container and does not have a definite shape, but has a definite volume. Solid particles are more tightly packed together, and certain solids even have particle patterns at the atomic level, which is why it has a definite shape and does not change unless it changes states.
