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.
In response to your question, the kind of energy the skier has is called potential energy.
A mixture can be called as a solution when the mixture is homogeneous
A. True
you can see plasma. Or, technically, you can see the energy (light) given off by a plasma.
(NH₄)₃PO₄ is a strong electrolyte which fully dissociates into its ions. The balanced equation for the dissociation is
(NH₄)₃PO₄ → 3NH₄⁺ + PO₄³⁻
The stoichiometric ratio between (NH₄)₃PO₄ and NH₄⁺ is 1 : 3
Hence, moles of (NH₄)₃PO₄ / moles of NH₄⁺ = 1 / 3
moles of (NH₄)₃PO₄ = 3 mol
Hence, moles of NH₄⁺ = moles of (NH₄)₃PO₄ x 3
= 3 mol x 3
= 9 mol
Hence, 3 moles of (NH₄)₃PO₄ give 9 moles of NH₄⁺.
