Answer:
SO4= is -2 each, and there are 2 of them,so 2 x -2 = -4, and Cr must be +4.
Energy in wind comes from the sun. for example, when the Earth’s surface absorbs the suns energy, it turns to heat. wind is produced by uneven heating from the earths surface by the sun. Since the earth's surface is made of various land and water formations, it absorbs the sun's radiation unevenly. The blades on the wind turbine move from the wind. i hope that made sense, if it didn’t i’m sorry, i hoped that hep though!
Answer: 9.98
Explanation:
1) The equation for the dissociation of pyridine is:
C₅H₅N₅(aq )+ H₂O(l) ⇄ C₅H₅NH⁺(aq) + OH⁻(aq)
2) Kb equation:
Kb = [C₅H₅NH⁺(aq)] [OH⁻(aq)] / [C₅H₅N₅(aq )]
Where:
[C₅H₅NH⁺(aq)] = [OH⁻(aq)] ← from the equilibrium reaction
[C₅H₅N₅(aq )] = 4.8 M ← from the statement
⇒ 1.9 × 10 ⁻⁹ = x² / 4.8 ⇒ x² = 9.12 × 10⁻⁹
⇒ x = 9.55 × 10⁻⁵ = [OH⁻(aq)]
3) pOH
pOH = - log [OH⁻(aq)] = 4.02
4) pOH + pH = 14
⇒ pH = 14 - 4.02 = 9.98
