Answer:
0.00944
Explanation:
Xenon mass number on the periodic table: 131.29
Oxygen mass number: 16.00
Add them to find the molar mass of xenon trioxide: 131.29+3(16) = 179.29g/mol
Convert this to moles

Answer: (although the question does not sate whether if you separate them physically or through energy. so i did both)
1. can be separated (When high-energy ultraviolet rays strike ordinary oxygen molecules (O2), they split the molecule into two single oxygen atoms, known as atomic oxygen)
2. can be separated, but through electrolysis, fiscally moving a crane to generate electricity to separate the molecules
3. Most solid particles, composed of diamagnetic or weak paramagnetic materials, cannot be extracted by a conventional magnetic separator. physically cannot be separated. but through heat yes
4. but there is a catch: doing so requires energy. ... If energy from coal were applied to drive the decomposition reaction, more CO2 would be released than consumed, because no process is perfectly efficient. so it cant be separated physically
5. it can be separated but it needs energy physically cannot be separated.
Explanation:
Nerves send signals to your brain from your spinal cord. If something is burning your nerves will send a pain signal from the area of the burn to your brain through you spinal cord. Then your brain sends a signal back to the nerves that there is pain and you should avoid it. Same with internal nerves and same with touch.
Explanation:
It is known that in a simple cubic unit cell the atoms are only present at the corner of the unit cell. This means that there are in total 8 atoms present in a simple cubic unit cell.
Therefore, in one simple cubic unit cell sharing of one atom is only
.
Hence, the total number of atoms in a unit cell will be as follows.
= 1
Thus, we can conclude that there is 1 calcium atom present in each unit cell.
