in a sodium borohydride reduction experiment explain any color changes observed when sodium borohydride was added.
Explanation of Ratios, In an unsymmetrical alkene, the boron atom adds predominantly to the least substituted carbon atom. For example, 2-methyl-2-butene gives the products shown below.
A buffer solution is prepared by dissolving 1.51 g NH3 and 3.85 g (NH4)2SO4 in enough water to make 0.500 L of solution.
Calculate the standard heat of reaction, or for this reaction using the given data. Also consider that the standard enthalpy of the formation of elements in their pure form is considered to be zero.
pKa of a carboxylic acid group found on a molecule of DOM is 4.2 and pKa of An amino group found on a molecule of DOM is 9.3. Explain how pH influences the ability of these groups to bind to metals. Illustrate how well each of these groups would b..
When the reaction 2H2S(g)-> 2H2(g) + S2(g) is carried out at 1065°C, Kp = 0.012. Starting with pure H2S at 1065°, what must the initial pressure of H2S be.

Titration of 15mL of 0.125M unknown base with 0.103M HCl required 18.2mL to reach the equivalence point. the pH at the equivalence point was 2.74.
b. Would the pH increases or decreases if the solution is disturbed by adding HBr?
The terms SCOT, WCOT, & PLOT are frequently used to describe types of GC columns. Specifically how do these columns differ from "Packed" columns in their structure and function
The base solution was added to the acid solution but was not stirred while temperature measurement were not made: c.) Some of the base splashed out of the calorimeter while pouring:
A collapsed balloon is filled with He to a volume of 11.2L at a pressure of 1.00 atm. Oxygen (O2) is then assed so that the final volume of the ballon is 21
