The number of molecules in one mole of any substance is equal to Avagadro's number
Avagadro's number is 6.023 X 10²³
Thus
1 mole = 6.023 X 10²³ molecules
for ammonia we are provided with three moles
so to obtain the total number of molecules of ammonia in three moles we will multiply the Avagadro's number with three
total molecules = 3 X 6.023 X 10²³
Total molecules of ammonia = 18.069 X 10²³
In scientific notation
Total molecules of ammonia = 1.8069 X 10²⁴ = 1.81 X 10²⁴
Answer: There are C - C bonds and C - H bonds.
trust me! I took a test with this question and got 100! :)
Heat fusion is the amount of energy required to convert one mole of ice into water, 16650J is per 50g so if we divide 16650 by 50 we find it per gram: 16650/50 = 333J/g or 0.33KJ/g
hope that helps :)
The answer is c.
Elements on the left side of the table are metals, such as sodium, lithium, potassium, etc.
Elements on the right side are non metals, such as Chlorine, Fluorine, Bromine, etc.
