How do prevailing winds affect air temperature?
GalinKa [24]

Answer:

Explanation:

Prevailing winds bring air from one type of climate to another. For example, warm winds that travel over water tend to collect moisture as they travel; the water vapor in the air will condense as it moves into colder climates, which is why temperate coastal areas often receive heavy rainfall

If a planet rotates 360 degrees during a 24 hour time period, what does that tell us about the planet? A. The middle of the plan
vlabodo [156]

The correct answer is C

<u />

<u>Explanation:</u>

360-degree rotation of the planet in 24 hours causes a 12-hour time clock. The earth rotates on its own axis and around the sun.

It completes one rotation on its own axis in 24 hours equal to 360 degrees which make one complete solar day. The part of the earth which is exposed to the sun has daytime while the other part experiences the night time.

The answer is: K is more reactive than Ca because K has to lose only one electron to complete its outermost shell.

Potassium is a chemical element with atomic number 19 (number of electrons is 19).

Electron configuration of potassium is: ₁₉K 1s²2s²2p⁶3s²3p⁶4s¹.

Potassium is the alkali metal and has a single valence electron in the outer electron shell.

Periodic law is the arrangement of the elements in order of increasing atomic number.

For example all alkaline metals (I group of periodic table, Na, K, Cs...) loose one electron in chemical reaction and react vigorously with water.

Reactivity series is an empirical progression of a series of metals, arranged by their reactivity from highest to lowest (alkaline metals have highest reactivity and Noble metals lowest reactivity).

The ionization energy (Ei) is the minimum amount of energy required to remove the valence electron, when element lose electrons, oxidation number of element grows (oxidation process).

Alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons (one electron, earth alkaline metals (right next to alkaline metals) have higher ionization energy than alkaline metals, because they have two valence electrons.
