One of the side effects of taking non-steroidal anti-inflammatories like aspirin and ibuprofen is a degradation of the integrity of the stomach lining. This is because the cyclooxygenase-1 (COX-1) enzyme responsible for part of the signaling cascade that leads to replenishment of the stomach lining is inhibited by these drugs. How does it differ from the COX-2 enzyme responsible for inflammation?
Calculate the molarity of an NH3 solution made up of 37.5 g of NH3 in 70.0 g of water. The density of the solution is 0.982 g/mL
Illustrate the structures of the 6 bromoalkenes (with the molecular formula C5H9Br ) that have a branched C chain, and that show neither chirality nor E,Z isomerism.
To creates a genetically modified transgenic goat that produce a protein that acts as a drug in its milk. The concentration of drug in the milk is 10 mM
By what factor (how many times) will the rate constant increase when the temperature is raised from 10°C to 28°C?
A 36.3 ml aliquot of 0.0529 M H2SO4 (aq) is to titrated with 0.0411 M NaOH (aq) What volumen (ml) of base will it take to reach the equivalence point
In the laboratory, a student named Georgia weighed 5.05 grams of an unknown solid mixture containing benzoic acid, copper (II) sulfate and sand.
An unknown compound contains carbon, hydrogen, oxygen, and sulfur atoms. When a 10.00 mg sample of the unknown compound was combusted, it produced 16.27 mg of CO2, 5.55 mg of water, and 7.90 mg of SO2.
An inflated balloon has a volume of 0.55 L at sea level (1 atm) and is allowed to rise to a height of 6.6 km, where the pressure is about 0.40 atm.
A solution is prepared by mixing 63.0 mL of 5.00 M HCl and 20.0 mL of 8.00 M HNO3. Water is then added until the final volume is 1.00 L. Calculate [H+], [OH -], and the pH for this solution.
Give explanation for arrangements how you decide the boiling points comparison - Arrange all these compounds in order of increasing boiling points
if the reaction between iron III ion and thiocyanate ion yielded an equilibrium concentration of .15M for each of these ions, what is the equilibrium concentration of the red iron III-thiocyanate complex
what concentration in ppm would it constitute? The effective volume of the earth's atmosphere is about 4.2 billion km^3, and take the average pressure to be 550 mm Hg and the average temperature to be -10 degrees C. The molar mass of air is 29 g/m..
