A 6.50-g sample of copper metal at 25.0 C is heated by the addition of 84.0 J of energy. The final temperature of the copper is ____ C.The specific heat capacity of the copper is 0.38J/g-K.
In trans-1,2-dibenzoylethylene, even though the conjugated C=O group frequency coincides directly with the expected C=C stretching fequency, we would not have expected to observe the late stretching mode in the infrared spectum. Why?
How much HCl must be added to a liter of buffer that is 1.5 M in acetic acid and 0.75 M in sodium acetate
However, if you treat formaldehyde (CH2O) with potassium cyanide in water, you will not produce the cyanohydrin. You may even produce C3H6O3 (i.e., dihydroxyacetone and glyceraldehyde). Explain this either in words or reactions.
