The amide group is an important structural unit in proteins. The simplest amide is formamide, HCONH2. In a valence bond picture of the C—N bond, hybrid orbitals of C overlap with hybrid orbitals of N. a. sp3; sp2
b. sp; sp2
c. sp2; sp
d. sp; sp
e. sp2; sp3

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

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.  

the answers are

c and c
