Answer:
Cu₂O.
Explanation:
copper = 7.298
copper oxide = 8.217
oxygen in copper oxide = .919 g
7.298 g of copper = 7.298 / 63.5 mole of copper
= .1149 mole of copper
.919 g of oxygen = .919 / 16 mole of oxygen
= .0574 mole of oxygen
ratio of mole of copper and oxygen
= .1149 / .0574 = 2
formula of copper oxide = Cu₂O.
Answer:
107.87 grams
Explanation:
One mole of silver weighs 107.87 grams
.
So carbon is 12(3), hydrogen is 1.01 (8), and oxygen is 16(2). Add it all together and you get 76.08 amu. That's molecular. The molar would be in grams (76.08 g). Hope that answered the question.

Answer:
The total energy to break all the bonds in 1 mole of 1-propanol, C₃H₈O, is 4411 kJ/mol
Explanation:
We note that propanol, C₃H₈O is also known as 1-propanol is written as follows;
CH₃CH₂CH₂OH which gives
CH₃-CH₂-CH₂-OH
Hence, the total number of bonds are;
C-H Bonds = 3 + 2 + 2 = 7
C-O Bonds = 1
O-H Bond = 1
C-C Bonds = 2
The bond energies are as follows;
C-H Bonds = 413 kJ/mol
C-O Bonds = 358 kJ/mol
O-H Bond = 468 kJ/mol
C-C Bonds = 347 kJ/mol
Energy required to break the bonds in 1-propanol is therefore;
C-H Bonds = 413 kJ/mol × 7 = 2,891 kJ/mol
C-O Bonds = 358 kJ/mol × 1 = 358 kJ/mol
O-H Bond = 468 kJ/mol × 1 = 468 kJ/mol
C-C Bonds = 347 kJ/mol × 2 = 694 kJ/mol
The total energy to break all the bonds in 1 mole of 1-propanol = 4411 kJ/mol.
