Missing question:
(a) 1s2 2s2 2p6 3s1
(b) 1s2 2s2 2p6 3s2
(c) 1s2 2s2 2p6 3s2 3p1
(d) 1s2 2s2 2p6 3s2 3p4
(e) 1s2 2s2 2p6 3s2 3p5
Answer is: a) 1s²2s²2p⁶3s¹ (sodium).
Sodium have the largest second ionization energy, because when he lost one electron(first ionization energy), he have stable electron configuration of noble gas neon (1s²2s²2p⁶), so sodium do not need to lost second electron, because he will have unstable electron configuration.
Water is an incomplete combustion as water is still produced by carbon monoxide and carbon are produced instead of carbon dioxide.
Answer:
Explanation:
Here, we want to select a disadvantage of the power sources
The two listed are examples of renewable power sources with no level of pollution
However, in the case of wind, a wind turbine is needed and could only work in places where the wind is prevalent enough throughout the year. Likewise, hydroelectric power, can only work where we have a flowing water source
Thus, there is a bane of geographic and climatic restrictions serving as a disadvantage
