Methanol, CH3Oh, is produce commercially by the catalyzed reaction of carbon monoxide and hydrogen
Explain possible reason for discrepency between the actual pH of the buffer and the reported pKa of the weak acid. (My case: actual pH =9.23, reported pKa =9.25)
What would be potential of a battery formed by perchlorate/chlorate ion pair
The charcoal from ashes found in a cave gave 3.34 14C counts per gram per minute. wood from the outer portion of a growing tree gives a comparable count of 16.0. The half life of 14C is 5700 years. How old are the ashes
