The correct matches are:
1. Exosphere - Temperatures reach as high as 2000 C yet it feels very cold
This is the top layer of the atmosphere. The atoms are so dispersed that despite it having very high temperature it doesn't feel like it at all.
2. Thermosphere - Particles that have enough energy can escape into space
The thermosphere is the fourth highest layer of the atmosphere. The atoms in this layer are relatively distant from one another, so the particles that have enough energy manage to escape easily into the exosphere and then the space.
3. Mesosphere - It is the coldest region of the atmosphere
The mesosphere is the third highest layer. In this layer the temperatures constantly drop, and they go down to -85 degrees, making it the coldest layer by far.
4. Stratosphere - Ninety percent ozone is in this layer
The startosphere has a separte zone in it which is dominated by only one gas, the ozone. It is called the ozone layer, the one that protects the Earth from too intense UV radiation, and in fact over 90% of this gas is locate here.
5. Troposphere - It is warm due to the heat from Earth's surface
The troposphere is the densest and lowest of the layers. It is the one that also has Greenhouse gases which manage to trap the heat that is radiated from the surface of the Earth, thus keeping this layer relatively warm.
Answer:
An unsaturated solution contains less than the most solute that can be mixed with and became part of a liquid at that temperature. ... A supersaturated solution can be prepared by preparing a saturated solution at a higher than desired temperature then allowing it to cool, decreasing the ability to be dissolved in something of the solute
Explanation:
Answer:
The equation shows balance.
Explanation:
You can easily count the number of elements on each side.
On the left side of the equation, you have 2 moles of Na and 2 moles of Cl.
On the right side of the equation, you also have 2 moles of Na and 2 moles of Cl because the two elements formed a compound meaning that whatever number is in front of them, both elements will receive the same number.
<h3>Answer:</h3>
The two possible compounds are;
1) Dimethyl Ether H₃C--O--CH₃
2) Ethanol H₃C--CH₂--OH
<h3>Solution:</h3>
Step 1: Calculate Moles of each Element;
Moles of C = %C ÷ At.Mass of C
Moles of C = 52.14 ÷ 12.01
Moles of C = 4.341 mol
Moles of H = %H ÷ At.Mass of H
Moles of H = 13.13 ÷ 1.01
Moles of H = 13.00 mol
Moles of O = %O ÷ At.Mass of O
Moles of O = 34.73 ÷ 16.0
Moles of O = 2.170 mol
Step 2: Find out mole ratio and simplify it;
C H O
4.341 13.00 2.170
4.341/2.170 13.00/2.170 2.170/2.170
2 5.99 1
2 6 1
Hence, Empirical Formula = C₂H₆O
<h3>Result:</h3>
As the molecular mass of compound is not given therefore, we can assume and guess the empirical formula to be the molecular formula. Hence, possible compounds are,
1) Dimethyl Ether H₃C--O--CH₃
2) Ethanol H₃C--CH₂--OH
