Answer:
Tetrahedral
Trigonal pyramidal
less than 109.5°
Explanation:
If a molecule has a hybridization of sp3 it must have four electron domains which corresponds to a tetrahedral geometry.
Now we were told that the molecule also has one lone pair. It means that one out of the four electron domains is composed of a lone pair. Thus the molecular geometry will be trigonal pyramidal (e.g NH3).
Recall that lone pairs usually decrease the bond angle to a value less than the expected value for that particular electron domain geometry.
The expected bond angle for a tetrahedral geometry is 109.5° but that of the trigonal planar geometry is less than this.
Answer:
67.3 atm
Explanation:
We'll begin by converting 25 ℃ to Kelvin temperature. This can be obtained as follow:
T(K) = T(℃) + 273
T(℃) = 25 ℃
T(K) = 25 + 273
T(K) = 298 K
Finally, we shall determine the pressure. This can be obtained by using the ideal gas equation as illustrated below:
Gas constant (R) = 0.821 atm.L/Kmol
Volume (V) = 212 L
Number of mole (n) = 584 moles
Temperature (T) = 298 K
Pressure (P) =?
PV = nRT
P × 212 = 584 × 0.0821 × 298
P × 212 = 14288.0272
Divide both side by 212
P = 14288.0272 / 212
P = 67.3 atm
Thus, the pressure is 67.3 atm
Answer:
Arrow a represents photosynthesis. 2 it transforms sunlight, water, and carbon dioxide into gluton, or food for the plants. 3 It recycles carbon because humans breath in oxygen and exhale carbon dioxide, plants then take in the carbon and exhale oxygen.
Explanation:
Answer:
From what I personally know, Acenaphthylene 75%. Empirical Formula (Hill Notation): C12H8. CAS Number: 208-96-8. Molecular Weight: 152.19. Beilstein: 774092. EC Number:
Explanation:
Acenaphthylene, a polycyclic aromatic hydrocarbon is an ortho- and peri-fused tricyclic hydrocarbon. The molecule resembles naphthalene with positions 1 and 8 connected by a -CH=CH- unit. It is a yellow solid. Unlike many polycyclic aromatic hydrocarbons, it has no fluorescence. Acenaphthylene/Formula is C12H8.
I'm not sure if this will help you but this is what I know so I hope it does :)
