Explanation:
How best to demonstrate the equivalence of hydrogens in
H 2 C = C H 2 ?
1 H NM R spectroscopy would be the best way to show this. The 4 hydrogens give the one signal.
C is the answer
Heat energy is transformed into electrical energy.
molarity = G/L/RFM
RFM = 120+32+48= 200
0.5/200 = 0.0025
