Answer:
The electron pair geometry is Trigonal planar
Molecular geometry - Bent
Approximate bond angle - <120°
Explanation:
The valence shell electron pair repulsion theory enables us to predict the shapes of molecules based on the number of electron pairs present on the valence shell of the central atom and based on the hybridization state of the central atom.
sp2 hybridization corresponds to trigonal planar geometry. Let us recall that the presence of lone pairs causes a deviation of the molecular geometry from the expected geometry based on the number of electron pairs.
Hence, owing to one lone pair present, the observed molecular geometry is bent.
Grains contain gold in forms that seem tailor-made for industrial use. Rumpelstiltskin, the fairy-tale rogue who spun straw into gold, has nothing on Miguel Yacaman and Jorge Gardea-Torresdey. The gold appears as particles mere billionths of a meter wide. ...
Theoretical yield:
02 -> H2O
1mol -> 2mol
2mol -> 4mol
32g -> 72g
Theoretical yield = 72g
Percent yield = actual yield/theoretical yield * 100
= 33.1/72 *100
=45.97%
The answer I believe would be A
the answer depends on the picture or the diagram.
