Answer:
Fluorine has a higher electronegativity than carbon
Explanation:
Electronegativity trend
-As you go from left to right across the periodic table, the electronegativity increases.
-As you go from top to bottom, the electronegativity decreases.
-We know that both carbon and fluorine are in the same energy level or period 2. However, Carbon is in group 14, which has 4 valence electrons, while fluorine is in group 17, which has 7 valence electrons. Therefore, fluorine has a higher electronegativity because fluorine is desperately wanted to gain 1 more valence electron to become stable (octet rule).
Answer: 
Explanation:
Molarity is defined as the number of moles dissolved per liter of the solution.
Normality is defined as the number of gram equivalents dissolved per liter of the solution.
Thus 
We assume that the volume of the molecules themselves in a gas sample is negligible compared to the bulk volume of the gas sample: this helps us to explain why gases are so compressible.
A mole of CO2 = 2 moles of O2
8 CO moles x 2 =
16 moles
Answer:
because it has lighter molecules.
