Answer:
The air above land also warms faster than air above the sea. Cooler higher pressure air above the ocean moves toward warmer lower pressue air above land.
1. a sulfur-32 atom contains 16 protons, 16 neutrons, and 16 electrons. what is the mass (in grams) of a sulfur-32 atom?
The mass in grams of a sulfur-32 atom is 32.
That is how the isotopes are identified, showing the mass number of the isotope, which is the sum of protons and neutrons: 16 protons + 16 neutrons = 32 mass number = mass in grams of the isotope.
2. the mass of a neutron is 1.67 x 10-24 g. approximately what number of neutrons would equal a mass of one gram?
divide 1 gram by the number of neutrons per gram:
number of neutrons = 1 g / 1.67 * 10 ^ - 24 g / neutrons = 0.5998 * 10 ^ 24 neutrons = 5.998 * 10 ^23 neutrons.
The hydroxide ion concentration, [OH-] = 2.439 x 10⁻¹⁰

Equilibrium of water and the ions :
![\tt Kc=\dfrac{[H_3O^+][OH^-]}{H_2O}](https://tex.z-dn.net/?f=%5Ctt%20Kc%3D%5Cdfrac%7B%5BH_3O%5E%2B%5D%5BOH%5E-%5D%7D%7BH_2O%7D)
Kc[H₂O] is the ion equilibrium constant for water ⇒ Kw.
The product of the concentrations of these ions (H₃O⁺ and OH⁻)at equilibrium at 25°C is 1.0 x 10⁻¹⁴ M
[H₃O⁺] [OH⁻] = 1.0 x 10⁻¹⁴ M = Kw
The hydrogen ion concentration of [H⁺]=4.1 x 10⁻⁵ M, so the hydroxide ion concentration, [OH-] :
![\tt 4.1\times 10^{-5}\times [OH^-]=1.10^{-14}\\\\(OH^-]=\dfrac{1.10^{-14}}{4.1\times 10^{-5}}\\\\(OH^-]=2.439\times 10^{-10}](https://tex.z-dn.net/?f=%5Ctt%204.1%5Ctimes%2010%5E%7B-5%7D%5Ctimes%20%5BOH%5E-%5D%3D1.10%5E%7B-14%7D%5C%5C%5C%5C%28OH%5E-%5D%3D%5Cdfrac%7B1.10%5E%7B-14%7D%7D%7B4.1%5Ctimes%2010%5E%7B-5%7D%7D%5C%5C%5C%5C%28OH%5E-%5D%3D2.439%5Ctimes%2010%5E%7B-10%7D)
Answer: the longitude line rotates with Earth, 360 degrees in 24 hours.
Explanation: In the old days, the position of the sun was used to tell which time of the day it is. But more modern findings, has shown that the longitude line matters too.
