Convert moles to mass.
mass C = 0.2 mol * 12 g / mol = 2.4 g
mass H = 0.4 mol * 1 g / mol = 0.4 g
So mass left for O = 6 g – (2.4 g + 0.4 g) = 3.2 g
Calculating for moles O given mass:
moles O = 3.2 g / (16 g / mol) = 0.2 moles
Answer:
<span>0.2 moles O</span>
B) 8
Neon is a noble gas which means it is in the 18th group which has 8 valence electrons. Thus Neon has 8 valence electrons.

please reffer
<span>The temperature change is greater when assuming that the mass is constant and the heat must be greater </span>in the result the heat of the metal as being reported too high.
hope it helps
