Answer:
A the uneven heating of earths surface
Explanation:
Because earths rotates on its axis, circulating air is deflected torward the right in the northern hemisphere and toward the left Southern Hemisphere. This is called the coriolis effect
Answer:
<u>A. H2O</u>
Explanation:
The balanced ionic equation for the reaction is:
→ 
This implies that the products of the reaction are zinc nitrate and hydrogen gas only.
<u>Therefore, the outlier from the options is water (H2O) </u>

Answer:
i) Ca = [Ar] 4s2
ii) Ar = [Ne] 3s2 3p6
III) Si = [Ne] 3s2 3p2
Explanation:
The Moeller diagram or Diagonals Rule is used to remember the order of filling of the atomic orbitals. It is simply a mnemonic rule.
The way to construct this diagram is to write the atomic energy levels (from 1 to 7) and the corresponding sub-levels next to it. Then diagonal lines are drawn from top to bottom.
The objective of the electronic configuration is to be clear about the distribution and the energetic order of the atoms, specifically, the distribution of the different levels and sub-levels of energy.
Electronic configuration:
Ca (Z= 20)
Ca: 1s2 2s2 2p6 3s2 3p6 4s2
Ar (Z= 18)
Ar: 1s2 2s2 2p6 3s2 3p6
Si (Z= 14)
Si: 1s2 2s2 2p6 3s2 3p2
2 and 3 are not possible because energy cannot be created nor destroyed. In order to break bonds, energy must be absorbed, so 1 is your answer!
