Describe and explain the possible effect on your results of the following experimental errors or variations. (a) You used solvent-grade (not anhydrous) diethyl ether for the reaction in part A. (b) After adding the bromobenzene solution in part A, you forgot to add anhydrous diethyl ether to the reaction mixture. (c) You used diethyl ether, rather than petroleum ether, to remove biphenyl from the crude triphenylmethanol.

43.452

step-by-step explanation:

284 times .153 = 43.452

shield volcanos are angry and get mad over the smallest things so much that there heads erupt   pahoehoe and a'a lava. a composite volcano is the poller opposite of a shield volcano. its   peaceful thing and knows how to control its emotions.      

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
