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

What is the percentage composition of carbon in the compound ch4

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
