Answer:
The Axis Powers took these aggressive actions prior to the outbreak of World War II which include the invasion of Ethiopia, Manchuria, and the Rhineland.
Explanation:
Axis Powers: It was the coalition of Germany, Italy and Japan against the <em>Allied Powers</em> (the United States, the Soviet Union, Great Britain, and China) in World War II.
- In 1930, the Japanese took control of railway track in Manchuria (a region in China) and in 1931, the Japan attacked the Chinese army claiming that the Chinese soldiers sabotaged the railway.
- On 3 October 1935, Italy invaded the Ethiopia (former name: Abyssinia) in the leadership of <em>Mussolini </em>to expand its territories.
- Germany in the leadership of Adolf Hitler occupied the Rhineland in 1937 by making excuse that the area is hostile and dangerous for them.

<u>Step 1: Define</u>
2.3 × 10²⁴ formula units KNO₃
<u>Step 2: Identify Conversions</u>
Avogadro's Number
Molar Mass of K - 39.10 g/mol
Molar Mass of N - 14.01 g/mol
Molar Mass of O - 16.00 g.mol
Molar Mass of KNO₃ - 39.10 + 14.01 + 3(16.00) = 101.11 g/mol
<u>Step 3: Convert</u>
<u /> = 386.172 g KNO₃
<u>Step 4: Check</u>

386.172 g KNO₃ ≈ 390 g KNO₃
Answer:
Fe
Explanation:
The electrical conductivity depends mainly on the type of chemical bonds between the atoms of a compound.
In the case of MgF2, FeCl3 and FeO3, these have the type of ionic bond. This means that in the atoms of the compound there is an electron transfer, to keep eight electrons in the outermost layer and thus resemble the electronic configuration of the inert gas closest to each of the two elements, due to this ions of opposite charges are formed that are held together by electrostatic forces. These types of compounds are good conductors of electricity, however, to have this property, they must be dissolved in water or molten.
In the case of Fe, however, the type of union between atoms is metallic. In this type of junction, valence electrons are quite free inside the metal, which makes it easy for them to move. For this reason, this compound will conduct electricity in a solid state.
Group 2 elements are the alkaline earth metals
