Given the reaction below, which is the oxidized substance?Mg + Cl2—>Mg2+ + 2C1-
A)2014
B)Cl2
C)Mg
D)Mg2+
Answers
The metal loses electrons, and when it becomes Mg2+, it loses two electrons, becoming oxidized. So, the correct option is D.
What is Oxidation reaction?
Initially, the word "oxidation" was used to refer to chemical processes in which a component reacts with oxygen. An illustration of this is the oxidation of magnesium in the formation of magnesium oxide when magnesium and oxygen react.
Antoine Lavoisier used the term "oxidation" to describe the reaction of a material with oxygen. The meaning was later expanded to cover additional reactions in which electron are lost, irrespective of whether oxygen was present, after it was realised that the substance loses electrons when it is oxidised.
In the aforementioned example, the metal loses electrons; specifically, it loses two electrons as it changes from Mg+ to Mg2+, getting oxidized.
Therefore, the correct option is D

Answer:
Mg ²⁺
Explanation:
Τhe metal loses electrons and in forming Mg²⁺ ,it loses 2 electrons and hence oxidized.
Mg(s) ⇒ Mg²⁺ + 2e⁻

Answer: because the vibration is of very short amplitude, at atomic scale.
Explanation:
The rocks are solid objects.
The solid physical state is characterized because the particles of the solid substances (molecules or atoms) are closely packed in fixed positions.
So, the particles of solids cannot slip (pass) on each other. Nevertheless, yet the particles vibrate rapidly. This vibration is the manifestation of the thermal energy of the substance.
The vibration of the atoms or molecules in a solid is of very short amplitude: it happens at atomic level, so that vibration is not visible. The vibration may be detected by x-ray diffraction but not by visible light.

Answer & Explanation:
The difference between a physical reaction and a chemical reaction is composition. In a chemical reaction, there is a change in the composition of the substances in question; in a physical change there is a difference in the appearance, smell, or simple display of a sample of matter without a change in composition.

O shows an inversely proportional relationship
O does not involve pressure changes
Answers
Answer:
A) involves changes in temperature
Explanation:
The figure is missing, but I assume that the region marked X represents the region in common between Gay-Lussac's law and Charle's Law.
Gay-Lussac's law states that:
"For an ideal gas kept at constant volume, the pressure of the gas is directly proportional to its absolute temperature"
Mathematically, it can be written as
where p is the pressure of the gas and T its absolute temperature.
Charle's Law states that:
"For an ideal gas kept at constant pressure, the volume of the gas is directly proportional to its absolute temperature"
Mathematically, it can be written as
where V is the volume of the gas and T its absolute temperature.
By looking at the two descriptions of the law, we see immediately that the property that they have in common is
A) involves changes in temperature
Since the temperature is NOT kept constant in the two laws.
