Draw any one of the skeletal structure of a secondary alkyl bromide with a molecular formula C6H13Br and two stereogenic centers. Indicate chirality by using wedge and hash wedged notation.
What is the molecular formula and structure? Also what does its infrared spectrum and NMR spectrum show?
When 0.060 mol of propionic acid, C2H5CO2H, is dissolved in 500 ml of water, the equilibrium concentration of H3O+ ions is measured to be 2.41 x 10-3 M. What is Ka for this acid?
A 14.5 gram sample of gas is found to have a volume of 2.8 liters at 275 K and 1.10 atm. What is the molar mass of this gas?
anesthetic contains 64.9 % carbon, 13.5 % hydrogen, and 21.6 % oxygen by mass. At 120 degrees C and 750 mmHg, 1.00 L of the gaseous compound weighs 2.30 g.
When a 2.3L sample of hydrogen gas at 25oC is heated to 120oC at constant pressure, what is the new volume of the gas?
Determine the molar mass of carbon dioxide by measuring the mass of an Erlenmeyer flask full of the gas. The following calculations are intended to familiarize you with the general procedure:
How will buffer capacity change if you add 0.2 M of benzoic acid to the buffer made of 0.3 M of acetic acid
Small samples of oxygen gas needed in the laboratory can be generated by any number of simple chemical reactions, such as 2KClO3(s) 2 KCl(s) + 3 O2(g) According to this balanced chemical equation, how many moles of oxygen gas are produced from the..
What are some of the characteristics that we want to observe? What might be your initial hypothesis? How would you set up an experiment to test your hypothesis?
Draw a free body diagram of a container of water that you are holding, you walk with the container at a constant speed and then stop abruptly.
while heating two different samples of water at sea level one boils at 102 c and one boils at 99.2 c. Calculate the percent error for each sample from the theoretical 100.0 c
Enough of a monoprotic acid is dissolved in water to produce a 0.0198 M solution. The pH of the resulting solution is 6.37. Calculate the Ka for the acid.
