Answer:
solar is better than wind
Explanation:
wind is not always blow in or blowing hard enough and most of day sun shines on us.
"Ions are formed when atoms lose or gain electrons in order to fulfill the octet rule and have full outer valence electron shells. When they lose electrons, they become positively charged and are named cations. When they gain electrons, they are negatively charged and are named anions." -Study.com
0.6 mol / L is the molarity of a solution prepared by dissolving 36. 0 g of NaOH in enough water to make 1. 50 l of solution.
The amount of a substance in a specific volume of solution is known as its molarity (M). The number of moles of a solute per liter of a solution is known as molarity. The molar concentration of a solution is another term for molarity.
The ratio employed to indicate the solution's concentration is called its molarity. Understanding a solution's molarity is important since it allows you to determine the actual concentration as well as whether the solution is diluted or concentrated.
Amount of NaOH = 36. 0 g
Amount of water = 1. 50 L
1 mol of NaOH = 40 g,
Moles of NaOH = 36. 0 / 40 g = 0.9 mol NaOH
Molarity of a solution = moles of solute / Liters of solution
Molarity of a solution = 0.9 / 1.50
Molarity of a solution = 0.6 mol / L

Answer:
wavelength λ = 35.92 pm
Explanation:
Given that:
The glancing angle (θ) = 10.42°
Bragg reflection n = 1
wavelength λ = ???
diameter d = 99.3 pm
Using the formula:
nλ = 2dsinθ
we have:
1 × λ = 2 × ( 99.3) × sin (10.42°)
λ = 198.6 × 0.18086
λ = 35.92 pm
When a physical change occurs, the arrangement of particles within the substance may change, but the atoms in the molecules remain bonded together.
