A. neutrons
Isotopes <span>contain equal numbers of protons but different numbers of neutrons in their nuclei.</span>
Answer:
The prefixes tell you how many of each there are.
Explanation:
So for this example, mono would mean there is one sugar, di meaning 2 sugars and so on. Hope this helped!
Here is a table:
mono- 1 hexa-6
di-2 hepta- 7
tri- 3 octo- 8
tetra- 4 nona- 9
penta - 5 deca- 10
Answer:
water
Explanation:
or h2o i mean theyre the same thing soo..
Answer:
636 balloons
Explanation:
If we assume that helium gas follows an ideal gas behaviour, we can use the ideal gas law to solve this problem as follows:
- We consider two different states, the initial given by the conditions of the problem statement and the final, when the tank reaches atmospheric pressure and it's no longer able to fill balloons:

- To find out what would be this volume 2, we use the Boyle's Law:

- Now we find the available volume to fill the balloons by substracting both, volume 2 and volume 1:

- Finally, we determine the quantity of ballons by dividing that available volume between the volume of each ballon:

Reason1: electrons on farther layers become free easyer
2nd reason: volume of atoms grows (from Helium to Xeon) so instead of boyle-mariot law equation (PV=vRT) is more accurate to use van der walls equations that adds to the boyle-mariot equation the volume occupied by the atoms of the gas to the volume of the space between the atoms P(Vm-b)=vRT
