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.
Answer:
Callie expect 600 molecules of CO2 to have been released as a waste during the same amount of time.
Explanation:
During cellular respiration 1 molecule of glucose undergoes oxidation to form 6 molecules of CO2 as a waste product.
According to the question callie determined that the germinating corn seed had utilized 100 molecules of glucose.
So 100 molecules of glucose will release 100×6=600 molecules of CO2 as a waste product.
Answer:
A mole (mol) is the amount of a substance that contains 6.02 × 10 23 representative particles of that substance. The mole is the SI unit for the amount of a substance. There are, therefore, 6.02 × 10 23 water molecules in a mole of water molecules. Water (H2O) is made from 2 atoms of hydrogen and 1 atom of oxygen.
