The complete table is shown in figure
a) NH3 is polar as the bonds between N and H are polar. Due to asymmetry in the molecule the molecule is polar
The shape of molecule is trigonal pyramidal while its electronic geometry is tetrahedral.
b) CO2: it is a non polar molecule with polar bonds. The molecule becomes non polar as the dipole moment cancel each other. [Dipole moment is a vector quantity]
The shape is linear.
Answer:
I believe the answer is C.
Explanation:
epic gamer explanation: C + 02 = CO2
Moles=mass/Mr
mass=454
Mr=12+16+16=44
So,454/44=10.31mol
Answer is:10.31mol
In the given system, A is the central atom which is surrounded by four B atoms and forms 4 covalent bonds. Ideally, this structure could correspond to a square planar molecular geometry. However, there are two lone pairs of electrons on the central atom A which must be considered in order interpret the electron geometry.
Thus the electron domain geometry around A is octahedral
Answer is: volume of CO₂ is 0,113 dm³.
Ideal gas law = pV = nRT.
p = 850 PSI = 5860543,6992 Pa.
Psi <span>is the abbreviation of pound per square inch.
T = 21</span>°C = 294,15 K.
n = 0,273 mol.
R = 8,314 J/K·mol.
V = nRT ÷ p
V = 0,273 mol · 8,314 J/K·mol · 294,15 K ÷ 5860543,6992 Pa.
V = 0,00011 m³ = 0,113 dm³.
