So this is actually a question in my biology class but it is a question about enantiomers so I figured I'd put it in Chemistry. Anyway! So the answer is A being that A is NOT an enantiomer. I'm not understanding why it's not if D is the same thing just with CH3 instead of a H. Any help is appreciated.

Discuss the distinction between a graduated pipette and a volumetric pipette. Volumetric pipettes are used to transfer one specified volume of liquid while graduated pipettes are used to transfer volumes other than specific volumes for which volumetric pipettes are calibrated.
Clarify the specific function of each and when each should be used. Volumetric pipettes ar
A polar covalent bond is a bond between two non-metals with different electronegativities. Only bonds between the same elements are truly nonpolar. The higher the difference in electronegativity, the more polar the bond is. Take a look at this table of electronegavities and let's try some examples.
How would i go about doing q 4-7 Can someone tell me how to set up these equations and put a ? where i should plug in my lab results...attached pic with questions
can someone help me out - ive done these questions but not so sure of my answer attached the two questions as a picture would really appreciate some help thanks
Questions about Buffers and pH levels and such.....
Research a buffer system that interests you and report the following:
(A) What is the system that is buffered? (B) What is the pH of the system? (C) What compounds are responsible for the buffered system? (D) What benefit does being at this pH serve? (E) How could this system be shifted
Chemical reactions are happening around us all the time; the CO2 in a can of soda is at equilibrium, batteries, fuel cells, acid rain, decaffeination of coffee (why bother?), reaction of sunscreen with skin, and on and on and on. There are also a number of household chemicals that when mixed can create an explosion or other hazardous situation. Try to think of a way chemicals are re
(A.) Calculate the cost per gram (g) of synthetic baccatin III, the Taxol precursor, using the following assumptions. Basically, what you are doing here is calculating how much it would cost to just synthesize the chemical needed to make Taxol in the laboratory, without relying on nature. Be sure to look at the attached picture (Figure 1) before trying to answer this question. You d
pH of blood is 7,4 K= (the concentration of H3O+)(the concentration of HCO3-)/(the concentration of CO2) = 4,5*10ˆ-7 How to calculate the rate of CO2/HCO3-
predict the initial rate if [no]= 0.30 m and [h2]=0.15 m what would happen to the initial rate of the reactonif[no]=0.60 m and [h2]=0.15 m instead. does your result make sense interms of order of reacton?

Question 1 of 12 0.0/ 4.0 Points A balloon filled with 0.500 L of air at sea level is submerged in the water to a depth that produces a pressure of 3.25 atm. What is the volume of the balloon at this depth?
Does anyone has any information on this forum, I have not had any luck!!!
In this discussion, you will be investigating the effects of acid rain in your location.
1. Identify your chosen area and include an image that shows an example of the effects of acid rain in your chosen area. If possible, find the example yourself and take your own picture. Explain the picture, what and where it is, what the damage is, if anything is being done about the

Propane, C3H8, is flammable and used in rural areas where natural gas is not available. What is the coefficient of oxygen in the balanced equation for the combustion of propane?
Exam tomorrow!! Please help me solve this! I tried everything!!! (Acid/base pH calculation)?
Some hydrogen and iodone are mixed at 229 degrees C in a 1.00L container. When equilibrium is established, the following concentrations ar present: [HI] = 0.490M [H2] = 0.080M [I2] = 0.060M
If an additional 0.300 moles of HI is then added, what concentrations will be present when the new equilibrium is established?
A typical automobile engine uses a lead-acid battery. During discharge, the following chemical reaction takes place: Pb (s) + PbO2 (s) + 2H2SO4 2PbSO4 (aq) + 2H2O (I) Determine the enthalpy change of this reaction, given the following equations:
1) Pb (s) + PbO2 (s) + 2SO3 (g) 2PbSO4 (s) ΔH°= -775 kJ
If a solution contains 28 g of potassium nitrate per 100 g of water at 25 degree
(e) (2 pts.) Suppose we are dealing with potassium nitrate as opposed to the chemical in the video. If a solution contains 28 g of potassium nitrate per 100 g of water at 25 degrees Celsius, is the solution unsaturated, saturated, or supersaturated? You may want to refer to Figure 13.4 in your text for help.
You were working in a biomedical research lab. You needed to find 25 mL of 1.5x10-3 M aqueous solution of blue dye for your next experiment. After a thorough search, you found a bottle of 0.01M, stock solution of the blue dye. How do you dilute the stock solution to the concentration you needed? You need to write a procedure that contains step-by-step instructions to be followed in
From a manufactory’s production line, there are two types of soda products: Apple and Cherry flavors. Your job is to randomly select samples from the each product line and monitor the quality of the products from data you have measured. You have used the same protocol of analysis for both products. In an initial analysis, 535 samples of Apple soda and 653 samples of Cherry soda samp

An experiment was carried out to determine the chemical formula of a metal oxide (MxOy) by burning the metal. The similar experiment but using Magnesium is described in the previous article: "Stoichiometric experiment explained". You can also watch the video for the experiment from the last linked item.
The data from the experiment can be found from this module
