Match each statement with a layer of the atmosphere. There will be two statements for each layer.

LuckyWell [14K]

The troposphere:

H. This layer can have thunderstorms or clear, sunny skies.

A. The biosphere interacts most with this layer.

The stratosphere:

B. It is the second layer from Earth's surface.

G. Winds are strong and steady in this layer.

The mesosphere:

E. It is heated by the ozone layer beneath it.

D. This layer is where most meteor showers occur.

The thermosphere :

F. It contains the ionosphere and exosphere.

C. It contains layers of single, unmixed gas.

Explanation:

Depending on the Earth's temperature the atmosphere can be separated into layers. The troposphere, the stratosphere, the mesosphere and the thermosphere are those layers. The lowest layer is named as Troposphere (0-10 km from the Earth outer surface), it comprises about 75% of the atmosphere's total air and nearly most the water vapor.

Stratosphere (10-30) includes much of the surface ozone. The change in height temperature arises as this ozone absorbs ultraviolet (UV) radiation from the sun. The temperature in Mesosphere (30-50 Km) declines again with height, hitting a minimum of about -90 ° C at the "mesopause." Above this thermosphere (50-400 Km) is settled which is a area where temperatures rise with height once again. The penetration of intense UV and X-ray radiation from the sun induces this temperature rise.

I In a smaller room, such as a bathroom, the reflected sound can reverberate (echo in many directions) off the smooth tile. Why

AVprozaik [17]

Answer:

See explanation

Explanation:

It is common knowledge that quite a number of people enjoy singing in the shower. There are reasons for this!

In the shower, there are many surfaces that reflect the sound of your voice as you sing. That makes your voice to sound more powerful and have more volume.

The reverberation of the sound makes the sound of your voice stronger and more intense altogether enriching the music produced as you sing.

Which of the following would indicate that a chemical change might be occurring

Murljashka [212]

Explanation:

During a chemical change, a new kind of matter is formed. Examples are combustion, rusting of iron, precipitation and souring of milk.

Here are some of the properties of chemical change:

They are not easily reversible
It leads to the production of new kinds of matter.
It involves change in mass.
It requires a considerable amount of energy.

A solid sample of Zinc Hydroxide is added to 0.350 L of 0.500 M aqueous Hydrogen Bromide. The solution that remains is still aci

Iteru [2.4K]

Answer:

6.499 g

Explanation:

One part of the aqueous HBr reacted with Zinc Hydroxide following the reaction:

Zn(OH)₂ + 2HBr → ZnBr₂ + 2H₂O

And the remaining HBr reacted with NaOH:

NaOH + HBr → NaBr + H₂O

First we calculate how many HBr moles remained after reacting with Zn(OH)₂. That number equals the number of NaOH moles used in the titration:

0.500 M * 88.5 mL = 44.25 mmol NaOH = mmol HBr

Now we calculate how many moles of HBr reacted with Zn(OH)₂:

Originally there were (350 mL * 0.500 M) 175 mmol HBr

175 mmol - 44.25 mmol = 130.75 mmol HBr

Then we convert those 130.75 mmoles of HBr to the Zn(OH)₂ moles they reacted with:

130.75 mmol HBr * $\frac{1mmolZn(OH)_{2}}{2mmolHBr}$ = 65.375 mmol Zn(OH)₂.

Finally we convert Zn(OH)₂ moles to grams:

65.375 mmol Zn(OH)₂ * 99.424 mg/mmol = 6499.8 mg Zn(OH)₂

6499.8 mg Zn(OH)₂ / 1000 = 6.499 g
