<u>Answer:</u>
Carbon and silicon both are tetravalent elements as compared to germanium, tin, and lead which are divalent.
That's because Ge, tin, and Pb show inert pair effect and has a greater nuclear effective charge on the 's' electrons due to poor shielding effect. .That's why these elements are not able to share their valence electrons while carbon and silicon does and show "catenation" which is the ability to form long chain molecules.
It’s a polyatomic and it has a negative charge. It’s located in the nucleus of the atom, along with the protons.
True becaus they are all polymers
Answer:
P(total) = 6.7 atm
Explanation:
Given data:
Partial pressure of N₂ = 3.5 atm
Partial pressure of O₂ = 2.8 atm
Partial pressure of Ar = 0.25 atm
Partial pressure of He = 0.15 atm
Total pressure = ?
Solution:
According to the Dalton law of partial pressure,
"The total pressure inside the gas cylinder having mixture of gases is equal to the sum of partial pressures of individual gas present in it"
Mathematical expression:
P(total) = P₁ + P₂ + P₃ + .........Pₙ
Now we will determine the total pressure of given gases.
P(total) = P₁ + P₂ + P₃ + P₄
P(total) =P(N₂) + P(O₂) + P(Ar) + P(He)
P(total) = 3.5 atm + 2.8 atm + 0.25 atm + 0.15 atm
P(total) = 6.7 atm
