Answer:
The First layer is the troposphere. The troposphere is what we live in. It creates weather for us. Second layer is the Stratosphere. You will find the ozone layer in it. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. Life as we know it wouldn't be possible without this layer of protection. Third layer is Mesosphere. The Mesosphere is very important for earth's protection. The mesosphere burns up most meteors and asteroids before they are able to reach the earth's surface. Fourth layer is Thermosphere. The Thermosphere absorbs the sun radiation making it very hot.
Explanation: I don't know if you include this one but the fifth layer is the Exosphere. Although the exosphere is the most distance layer of earth's atmosphere it is the layer that is the planet's first line of defense against the sun's rays. It is also the first layer to come into contact and protect the earth from meteors, asteroids, and cosmic rays.
Answer:
It has 6 protons and its Carbon 14
Explanation:
To know the mass of the acetone we must multiply the volume of the acetone with its density. but since the volume is in ml units and the density is in g/cm3. we must convert it firstsince 1 ml = 1 cm3
so mass acetone = 13.06 mL (0.7857 g/ml)mass acetone = 10.848 g
how many protons it has/atomic number and atomic mass if that what ur trying to ask
