Answer:
Isotopes of an element share the same number of protons but have different numbers of neutrons. ... This means that all three isotopes have different atomic masses (carbon-14 being the heaviest), but share the same atomic number (Z=6).
Explanation:
The electron affinity increases from left to right
So the mole number of 319 ml of 6.80 M HCl is 6.80*319*10^(-3)=2.17 mol. So the volume of 6.00 M HCl needed is 2.17/6.00=0.362 L=362 ml
Answer:
Geothermal energy is the heat from the Earth
Explanation:
It's clean and sustainable. Resources of geothermal energy range from the shallow ground to hot water and hot rock
Answer:
See explanation
Explanation:
Racemization is said to occur when a 1:1 ratio of (+) and (-) enantiomers of a compound are produced in a reaction.
The reaction of optically active (R)-2-methylcyclohexanone with either aqueous base or acid leads to the formation of a planar enol species for reaction with acid and a planar enolate species for reaction with base.
Both reactions involves the formation of achiral species which reverts back to the chiral product with equal chances of the formation of both enantiomers of the product during the process. This leads to racemization of the product in both cases.
