In lab (write this down in your lab protocol), you will be given a stock solution that has a glucose concentration of 60 mg/dL. You need to make 1 mL of each of the following glucose concentrations: 0.94 mg/dL, 1.88 mg/dL, 3.75 mg/dL, 7.5 mg/dL, 15 mg/dL, and 30 mg/dL. Distilled water will be the solvent in these dilutions. Enter your numbers only. 1. What is the dilution factor for this serial dilution? 2. What is the V2 for this serial dilution in mL? 3. What is the V1 for this serial dilution in mL?

The human eye contains a molecule called 11-cis-retinal that changes shape when struck with light of sufficient energy. the change in shape triggers a series of events that results in an electrical signal being sent to the brain that results in vision. the minimum energy required to change the conformation of 11-cis-retinal within the eye is about 164 kj/mol.

According to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? view available hint(s) according to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? trigonal bipyramidal tetrahedral square planar determination of electron geometry requires information on whether the electron groups are lone pairs or bonding groups.
