HOW DOES ENERGY FROM THE SUN ULTIMATELY CAUSE THE BLADES ON THESE WIND TURBINES TO MOVE?

Anarel [89]

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!

Write the resonance forms of ozone, O3, the component of the upper atmosphere that protects the Earth from ultraviolet radiation

aleksklad [387]

Answer:

The resonance forms of O3 are attached as an image.

Explanation:

A compound with different contributing structures comes together and forms a resonating or intermediate structure that best describes the properties of that compound.

The given compound is ozone, having the chemical formula

O3 = 6 electrons * 3 = 18 electrons

O → prefers to have a complete their octet

The bonding electrons and lone pair electrons are radical electrons that are present on the oxygen atoms tend to delocalize and results in various resonating forms of O3.

How many moles are contained in 70. milliliters of a 0.167 M solution of p-toluidine hydrochloride? Enter only the number to two

kramer

Answer: The amount of p-toluidine hydrochloride contained is 2.4 moles.

Explanation:

To calculate the number of moles for given molarity, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Moles of solute}\times 1000}{\text{Volume of solution (in mL)}}$

Molarity of p-toluidine hydrochloride solution = 0.167 M

Volume of solution = 70. mL

Putting values in equation 1, we get:

$0.167=\frac{\text{Moles of p-toluidine hydrochloride}\times 1000}{70}\\\\\text{Moles of p-toluidine hydrochloride}=\frac{(0.167\times 70}{1000}=2.38mol=2.4mol$

Hence, the amount of p-toluidine hydrochloride contained is 2.4 moles.
