An attempt at synthesizing a certain optically active compound resulted in a mixture of its enantiomer. the mixture had an observed specific rotation of +13.5degree. if it is known that the specific rotation of the r enantiomer is -39.2degree. determine the percentage of each isomer in the mixture.
r enantiomer = %
s enantiomer = %

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
