Covalent bonds do not involve electron transfer because in covalent bonds, the electrons are shared between the atoms to form the molecule rather than being transferred to form ions as it is in the case of ionic bonds.<span />
54 would be the correct answer i beleive
Answer:
The answer is D.
Explanation:
Volume (V) = l x w x h
V = 4 x 5 x 1.2
V = 20 x 1.2
V = 24
Density = Mass/Volume or D = M/V
D = 85,000/24
D = 3541.66666666
