Answer:
36 grams as 1 mole is 12 grams
It depends on the number of valence electrons required to make octet or duplet( in case of H)
. For example, Nitrogen(atomic number = 7) has electronic configuration(2,5) which means nitrogen has 5 valence electrons and requires 3 more electrons to complete its octet. After gaining 3 electrons from atoms of an element with less electronegativity than N, it forms nitride ion ().
Hope this helps.
Answer:
the answer is Z b/c wehave to forces and they have different direction. then search the sum of the forces. thus we gain 40 N to right.
