What mass of ammonium chloride should be added to 2.65 L of a 0.165 M NH3 in order to obtain a buffer with a pH of 9.60
Trouble understanding the relationship between the Ka and how acidic a chemical is. Is it safe to say that the more acidic a chemical is the higher the Ka value will be
Find out the reactants one would need in order to produce the two esters you drew and named in Q1. Demonstrate the balanced reaction for the production of both esters
If a triacylglycerol in peanut oil that contains one palmitic acid, one oleic acid, and one linoleic acid is completely hydrogenated, what is the product
This reaction was catalyzed by an acid. During the work-up why did you extract with water and not sodium hydroxide. Extracting with sodium hydroxide will convert the final product back to the starting material.
The increase in volume is due to the H2 gas created. 50 g of tin (Sn) is 0.421 moles. That is also the number of moles of H2 that are created. Use tha ideal gas law to compute the added volume due to that gas.
