Answer:
Balanced Chemical equation:
4Na + O₂ → 2Na₂O
Explanation:
Chemical equation:
Na + O₂ → Na₂O
Balanced Chemical equation:
4Na + O₂ → 2Na₂O
Four mole of sodium combine with one mole of oxygen and form two mole of sodium oxide.
Coefficient with reactant and products:
Na 4
O₂ 1
Na₂O 2
Oxygen is present in group sixteen and have six valance electrons. while sodium is alkali metal and present in group one and have one valance electron.
Oxygen needs two electron to complete the octet while sodium need to lose the one electron to get the complete octet.
When oxygen is combine with sodium it gain its two valance electrons from two sodium atom and form anion while sodium loses its valance electron to wards oxygen and form cation. The bond form between them is ionic because one is metal and other is non metal and electrons are completely transfer from two sodium atom to one oxygen atom.
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
C.)atmosphere distorts and blocks the light
