Explanation:
Loss of one or more electrons by a neutral atom will help the neutral atom to acquire a positive charge.
For example, atomic number of sodium is 11 and to stabilize itself it needs to lose one electron. So, by losing an electron it will change into ion.
On the other hand, gain of one or more electrons by a neutral atom will help the neutral atom to acquire a negative charge.
For example, Cl has atomic number 17 and to fill its octet completely it need one more electron. So, by gaining an electron is will change into ion.
Therefore, we can conclude that an ion is an atom with a net electrical charge due to loss or gain of electrons.
1.05moles
Explanation:
Given parameters:
Number of molecules of C₂H₆ = 6.29 x 10²³molecules
Unknown:
Number of moles = ?
Solution:
The mole is the amount of substances that contains Avogadro's number of particles i.e 6.02 x 10²³
To find the number of moles:
number of moles =
number of moles =
number of moles = 1.05moles

Answer:
<h2>36.09 L</h2>Explanation:
The initial volume can be found by using the formula for Boyle's law which is
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume.
Since we're finding the initial volume
We have
We have the final answer as
<h3>36.09 L</h3>Hope this helps you
