Design a synthesis of 2-ethoxy-2-methylpropane from 2-methylpropene. q1 Part 1: Choose the best option for the immediate precursor to the target molecule. p1 p1c p1d4 p1d3 p1d2 6412p1a SN1 solvolysis of the tertiary bromide with the appropriate alcohol will produce the target molecule. Part 2 out of 6 Choose the best option for the precursor needed to make the alkyl bromide. p2 p2d3 p2d2 p2d1 p2c p2d4

hloride, what is the mass of calcium in

explanation:

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.  

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally

the objects have the same charge is correct.
