Based on what you know about the structure of humic material (HM), explain why it is more likely that HM molecules in solution have net negative charge rather than net positive charge.
Homework Answers
The major constituents of Humic material are Humic and Fulvic Acids. These compound consist of many carboxylic and phenol substituents. Since these groups tend to lose a proton in solution a net negative charge can be observed. The following is the structure of Fuvic Acid for reference.

Briefly explain your observations in terms of osmosis and what you know about the structure of plant cells. Address the following points explicitly: • in comparing the Tap Water and Salt Water treatments to each other and to the No Treatment condition, whether there is an apparent change in the size of the cells, and why or why not • the net direction of water flow for each treatment • the net direction of solute flow for each treatment •...

1. Calculation: Using the Henderson-Hasselbalch equation, explain mathematically why a solution is at a pH below the pKa for an acid that more than 50% of the molecules have the proton on (not off). 2. Calculation: If you have a pH of 5.5 for a weak acid with a pKa of 4.76, then is there more A- or more HA in the solution? Explain why in words using your knowledge of positive or negative log numbers.

Based on what you know about the olfactory system, which of the following could you confidently predict about two odorant molecules that have very similar chemical structures? They will have very similar odor Not enough information. There is not always a clear relationship between chemical structure and perception or response profiles They will have the same patterns of activation in the olfactory bulb They will have very similar patterns of olfactory receptor neuron activation They will have the same patterns...

Hi! can you please explain step by step how i would go about
proposing a structure for this?
I know that DEPT-90 shows CH groups & DEPT-135 shows CH
& CH3 in the positive region and CH2 in the negative region. I
also know that the normal graph shows the C's. However, i have
answer to this question, but I have no idea how they came up with
it. Can you please explain step by step your rationale how to...

Based on what you know about evolutionary mechanisms, which species of Emerald Finch most likely diverged from the ancestral state via genetic drift? Explain your answer. Cancer can loosely be defined as abnormal and uncontrolled growth of a tumor. Why does it make sense that Actinomycin D, which binds to transcription initiation complexes, is used as an anticancer drug?

Give an example of a negative or positive externality that you know about or have experienced. Once you have identified the externality, describe what is causing it and who it is effecting. Once you have done this, discuss the public policy or the private solution that is being applied to the negative or positive externality and discuss if it's working and how the externality is being internalized.
