What are the importance of amino acids in physiological processes, in nutrition and in the different uses of these.
Suppose that 28 g of gold is initially at 29.0 degrees celsius. What is the final temperature gold upon absorbing 2.25 kJ of heat?
In the procedure, you extracted sodium chloride from the insoluble silicon dioxide and calcium carbonate by dissolving the sodium chloride in distilled water. However, calcium carbonate is actually slightly soluble in water
The vapor pressure of pure propyl chloride is 347 torr at 25°C and that of pure propyl bromide is 133 torr at 25°C. Assume that the solution is an ideal solution.
IR of Benzpinacol and to what carbon, proton, or functional group (respectively) would each peak belong?
write the equation of the following drugs with water- 1) benzoic acid with water
In a titration, 0.0 mL of 0.025 M hydrochloric acid is added to 30.0 mL of 0.030 M ammonia. What is the pH of the resulting mixture?
describe an experiment using only hot and cold water that would allow you to verify that the heat capacity of your coffee-cup calorimeter
Explain from a micro and macro perspective what would happen and what might be observed when a bimetallic strip of aluminium and copper is heated from 27 degrees to 327 degrees?
Compute the number of gms of CoCl2 that would be needed to prepare the solutions:(a) 550 mL of a 1.75 M solution (b) 210 mL of a 0.0180 M solution.
What is the molality of a solution that contains 80.0 g Al2(SO4)3 in 625 g H2O?
Really confused on calculating/finding the half-equivalence point in a titration curve. This was a lab experiment done in my chem lab. We added 0.0750 M NaOH to acetic acid (pipet 10.00mL of ~0.1M HCH3CO2 into the beaker and add 40mL of DI water).
How many mL Hydrochloric acid of 0.1 M must be added to 100 mL of a 0.2 M solution of tris base to form a buffer ( pH 7.8)?
