Manganese, Mn, forms two ions, one with a 2+ charge and one with a 3+ charge. What is the formula for manganese (II) sulfide?
maria [59]
It would be MnSO4

The (II) lets you know it’s the form with a 2+ charge and Sulfate has a 2- charge

These will cancel out making it plain MnSO4

If it was manganese (iii) sulfide the answer would be Mn2(SO4)3

Match each statement with a layer of the atmosphere. There will be two statements for each layer.
LuckyWell [14K]

<u>The troposphere: </u>

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

A. The biosphere interacts most with this layer. 

<u>The stratosphere:</u>

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

G. Winds are strong and steady in this layer. 

<u>The mesosphere:</u>

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

D. This layer is where most meteor showers occur. 

<u>The thermosphere :</u>

F. It contains the ionosphere and exosphere. 

C. It contains layers of single, unmixed gas. 

<u>Explanation:</u>

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.
