Answer:
a)
b)
Explanation:
a) The reaction:
The free-energy expression:
![E=E_{red}-E_{ox]](https://tex.z-dn.net/?f=E%3DE_%7Bred%7D-E_%7Box%5D)
The element wich is reduced is the Fe and the one that oxidates is the Mg:
The electrons transfered (n) in this reaction are 2, so:
b) If you have values of enthalpy and enthropy you can calculate the free-energy by:
with T in Kelvin
Answer:
yes they are broken down into smaller units
Word Equation: Barium chloride solution reacts with sodium sulfate solution to produce sodium chloride and barium sulfate.
Answer:
Some of the physical and chemical properties of magnesium are:
-The term ‘magnesium’ is derived from the Greek word magnesia, which refers to the name of the place from where it was extracted.
-Magnesium is closely related to manganese and magnetite.
-About 2.1% of the Earth’s crust contains magnesium. This makes magnesium the 6th most found element.
-The biggest deposits of magnesium is found in the seawater. It has been calculated by scientists that a cubic mile of seawater contains about 6 million tons of this element
2nd answer:
Physical Properties of Magnesium: ”I’m a highly stable element, so you can count on me”
Chemical Properties of Magnesium: ”I love to travel but I do corrode aluminum so we won’t be flying off on adventures in airplanes planes anytime soon
