The noble gas configuration means that the electronic configuration for Lithium is written in shortcut by starting with the symbol for the nearest noble gas. Note that the noble gas should be lighter than the said element. In here, the nearest noble gas to Lithium is Helium (He). Then, add the additional electrons. Thus, the noble gas configuration would be: <em>[He]2s¹.</em>
Answer:
1.5 mol H2O
Explanation:
2C2H6 + 7O2 -> 4CO2 + 6H2O
The limiting reactant is C2H6
30 g C2H6 ->1 mol C2H6
15 g C2H6 -> x x= 0.5 mol C2H6
2 mol C2H6 -> 6 mol H2O
0.5 mol c2H6 -> x x = 1.5 mol H2O
