If you were told an atom was an ion, you would know the atom must have a neutral charge. charge. negative charge. positive charg
2 answers:
<u>Answer:</u> When an atom is an ion, it must have a charge.
<u>Explanation:</u>
An ion is formed when a neutral atom looses or gains electrons.
- When an atom looses electrons, it results in the formation of positive ion known as cation. <u>For Example:</u> Sodium looses 1 electron to form
ion.
- When an atom gains electrons, it results in the formation of negative ion known as anion. <u>For Example:</u> Chlorine gains 1 electron to form
ion.
Hence, when an atom is an ion, it must have a charge.

The partial pressure (Px) of a gas in a gas mixture is equal to its mole fraction (Xi) multiplied by the total pressure (P) of the gas mixture. That means that we have to calculate the mole fraction of each gas, then calculate its partial pressure. The mole fraction of a gas is its number of moles (n) divided by the total number of moles.
Dalton's law of partial pressures is a gas law that states that the total pressure exerted by a mixture of gases is equal to the sum of the partial pressures exerted by each individual gas in the mixture. The mole fraction of a given gas in a gas mixture is equal to the ratio of the partial pressure of that gas to the total pressure exerted by the gas mixture. This mole fraction can also be used to calculate the total number of moles of constituent gas if the total number of moles of the mixture is known. In addition, the mole fraction can also be used to calculate the volume of a certain gas in a mixtur.

Hello there!
This is an interesting thing I did last year in my Sophomore year.
Let me try this out!
First, we wanna start by drawing a standard structure with carbon in the middle, as hydrogen can only form one bond. (Please see pictue #1)
We know that the center carbon has too many bonds (maximum of 4), so we will shift two hydrogen over to the other carbon. (See picture #2)
Now each carbon has too few bonds, so we will make a double bond between them.
The last picture is the correct structure of C2H4, ethylene. The octet rule is kept.
I am terrible when it comes to drawing things. I hope this helps~!
