C. Chemists have learned how dangerous chemicals can be
Explanation:
Substance A will sink because it is more dense than water. An object that is more dense than water will sink and an object that is less dense than water will float.
Where else but from the surroundings?
<span>Mass of CH2 = 12 + 2 = 14 g/mol
The number of CH2s there are.
So since the total mass is 84.2 g/mol.
The solution is
84.2/14 = 6.012 thus the answer is 6
There are 6(CH2)
So the molecular formula is C6H12</span>
Cobalt has a higher atomic radius
