Draw the curved arrows to complete the given radical reaction mechanism involving bond breaking. There is a scheme of a reaction where CHCH3 with a benzene ring and an OCH3 group attached to the first (from left to right) carbon atom decomposes into an OCH3 radical and CHCH3 with a benzene ring attached to the first (from left to right) carbon atom and an unpaired electron on the first carbon atom. The reactant has two electron pairs at the O atom. The OCH3 radical has two electron pairs and one unpaired electron on the O atom.

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³

answer b

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.
