When a molecule loses or gains an electron it becomes an ion.
"If it gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion."
The reason for this is because of D. Mars is a long distance away.
Third quarter (or last quarter)
Answer:
Explanation:
The volume and amount of gas are constant, so we can use Gay-Lussac’s Law:
At constant volume, the pressure exerted by a gas is directly proportional to its temperature.
Data:
p₁ =5.7 atm; T₁ = 100.0 °C
p₂ = ?; T₂ = 20.0 °C
Calculations:
1. Convert the temperatures to kelvins
T₁ = (100.0 + 273.15) K = 373.15
T₂ = (20.0 + 273.15) K = 293.15
2. Calculate the new pressure
Answer:
8
Explanation:
Methyl anion (CH₃⁻)
Valence electrons of carbon = 4
Valence electrons of hydrogen = 1
Charge = -1 which means addition of 1 electron
The total number of the valence electrons = 4 + 3(1) + 1 = 8
<u>In the Lewis structure of anion also, 1 lone pair and 3 bond pairs on the carbon atom which corresponds to 8 valence electrons.</u>
