Write a chemical equation for the formation of methionyl glycine from the constituent amino acids.
Propose a structure for a molecule with a molecular formula C10H13NO and the following 1H NMR data. Briefly explain your answer.
Compare a refrigerator set at four degree celcius and a freezer set at minus twenty degree celsius, both of which are operating in the room at the temperature of eighteen degree celsius.
What would happen if you increase the pH of this acidic solution by addition of a strong base such as KOH? b.) Write the balanced equation for the reaction (a.) and identify both the stronger acid and base and the weaker acid and base.
Compare the absorbances you obtained for the SPF 8 and SPF 15 preparations. If both preparations contain the same ingredients, how much must the concentration of UV-absorbing materials
Describe the various strategies for the excretion of nitrogenous wastes employed in higher animals (chordates), both human and non-human.
One of the most historically significant studies of chemical reaction rates was that by M. Bodenstein (Z. Physik. Chem. 29 (1899) 295) of the gas phase reaction and its reverse, with rate constants and , respectively. The measured rate constants a..
Calculate the pressure and the temperature of the compressed gas. In a diesel engine the compression ratios are typically much higher; redo the same calculation for the compression ratio of 20:1.
Hydrochloric acid reacts with aluminum to form aluminum chloride and gseous hydrogen. What's the mass of aluminum required to produce 1.0kg of aluminum chloride if there is excess acid?
Phosphoric acid, H3PO4(aq), is a triprotic acid, meaning that one molecule of the acid has three acidic protons. Estimate the pH, and the concentrations of all species
The air pollutant NO is produced in automobile engines because of the high-temperature reaction below. If the initial concentrations of N2 and O2 at 1000 K are both 1 M, what are the concentrations of NO, N2, and O2 when the reaction mixture reach..
First determine the number of moles of rm Na^+ using the given molarity and volume. Next, use the chemical formula to determine the number of moles of rm Na_3PO_4 needed. Finally, convert moles to grams using the molecular weight of the compound.
