Answer: polar,non polar
Explanation:
The electronegativity of C is 2.5 and of O is 3.5 .The difference in electronegativity(3.5-2.5=1.0) is 1.0 and as per rule if the difference in electronegativity of atoms in a bond is >0.4 then the bond is considered polar. So in this case C-O bond is polar.
However, the symmetrical arrangement of the bonds in the molecule of CO2 makes its non polar.The CO2 molecule is linear so the C-O dipole moment on either side will cancel out each other hence the net dipole moment will be zero.
That is correct hope that helps
I assume this is a true or false question. I would say true
Answer:
P₂ = 2.88 atm
Explanation:
Given data:
Initial volume of gas = 1.8 L
Final volume = 750 mL
Initial pressure = 17.5 Psi
Final pressure = ?
Solution:
We will convert the units first:
Initial pressure = 17.5 /14.696 = 1.2 atm
Final volume = 750 mL ×1L/1000L = 0.75 L
The given problem will be solved through the Boly's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
1.2 atm × 1.8 L = P₂ ×0.75 L
P₂ = 2.16 atm. L/ 0.75 L
P₂ = 2.88 atm
