Answer:
(F) (O) (N) (C) (B) (Na)
Explanation:
Fluorine has the highest electronegativity,while Oxygen comes 2nd. Then Nitrogen 3rd, Carbon 4th then Boron 5th while Sodium has the lowest electronegativity.
Answer:
C₃H₃NaO₂
Explanation:
The percentage composition of the artificial snow is given.
The smallest whole number ratio of the atoms in a compound gives the empirical formula.
To find the empirical formula of the artificial snow, we use the method below;
Percentage composition of oxygen = 100 - (38.3+3.33+ 24.4) = 33.97
Elements C H Na O
Percentage
Composition 38.3 3.22 24.4 33.97
Number of
moles 38.3/12 3.22/1 24.4/23 33.97/16
3.19 3.22 1.06 2.12
Divide by
the smallest 3.19/1.06 3.22/1.06 1.06/1.06 2.12/1.06
3 3 1 2
The empirical formula of the compound is C₃H₃NaO₂
The answer to the question is a
CH4 + O2 -> H2O + CO2
Then balance:
CH4 + 2 O2 -> 2 H2O + CO2
A methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogenatoms — CH3. In formulas, the group is often abbreviated Me. Such hydrocarbon groups occur in many organic compounds. It is a very stable group in most molecules.
