Answer:
The equation is Fe₂O₃ + CO ⇒ Fe + CO₂.
The balanced reaction equation is Fe₂O₃ + 3CO ⇒ 2Fe + 3CO₂.
Explanation:
First, we have to write our equation. It's actually pretty straightforward - first we look for our reactants (looks like it's Fe₂O₃ and CO), then we look for our products (Fe and CO₂). Then, we have to balance it so that both sides have the same number of both element.
Currently, we have the equation Fe₂O₃ + CO ⇒ Fe + CO₂. There are 2 Fe atoms, 4 O atoms, and 1 C atom on the left side. There is 1 Fe atom, 2 O atoms, and 1 C atom on the right side.
First thing we can do is give our Fe on the right side a coefficient of 2. This will make it equivalent to the 2 Fe atoms on the left side:
Fe₂O₃ + CO ⇒ 2Fe + CO₂
Next, we need to make sure that we have the same number of C and O atoms on each side. This takes a little bit of thinking, but what we have to do is give CO a coefficient of 3 and CO₂ a coefficient of 3. This gives us 6 O atoms on the left side (when we include the O₃) and 6 O atoms on the right side (since there are 3 O₂ atoms and 3 times 2 is 6). Here's what that looks like:
Fe₂O₃ + 3CO ⇒ 2Fe + 3CO₂
And that's how I balanced the equation. It can be confusing, but with enough practice, it will get easier and easier. :)

Calculate the maximum mass of magnesium oxide that could be produced in the reaction.
2 moles of Mg produce 2 moles of MgO
1 mole of Mg weighs 24.3 and produces 1 mole of MgO
Mg HAS AN ATOMIC MASS OF 24.3
Mg HAS A MOLAR MASS OF 24.3 +16 = 40.3gm/mole
so 24.3 gm of Mg produce 40.3 gm MgO
set up the ratio
10 gm Mg/x of MgO = 24.3/40.3
or
10/x = 24.3/40.3
cross multiply and isolate x (use Algebra I)
24.3x =403
x=403/24,3 = 16.58 gm MgO

E) This is not an oxidation/reduction type of reaction
Answers
Answer:
E) This is not an Oxidation/ Reduction type of reaction
Explanation:
Oxidation involves the loss of electrons while reduction involves the addition of electrons. None of the elements change their oxidation number in the reaction, so this is not an oxidation/reduction type of reaction.
The addition of oxygen and the removal is electrons is called oxidation. In a reaction that has both the process is called the redox reactions.
The correct answer to the question is option E
In this reaction, not any elements have the loose and gain the electrons in order to tell the oxidation and reduction.
This reaction is a neutralization reaction.
Hence, the correct answer is E that is not an oxidation/reduction type of reaction.

The distance between the objects' centers and The amount of matter in the objects are two characteristics determine the strength of the gravitational force between two objects.
What is Gravitational force?All objects with mass or energy are attracted to one another by gravity, which is a fundamental interaction.
The electromagnetic force, the weak interaction, and the strong interaction are all significantly stronger than gravity, which is by far the weakest of the four fundamental interactions.
As a result, it has no appreciable impact on subatomic particle level phenomena. However, at the macroscopic level, gravity is the most important interaction between objects and governs the motion of planets, stars, galaxies, and even light.
Therefore, The distance between the objects' centers and The amount of matter in the objects are two characteristics determine the strength of the gravitational force between two objects.

An initial solution of orange juice has a solute concentration of 0.50 M and a volume of 155.0 mL. What is the final solute concentration of the juice after its been diluted with 52.5mL of water?
the old molarity was 0.50 M, and a volume of 1555.0 ml
the new volume is a total of 155.0 ml + 52.5 ml =207.5 ml
so the new molarity is (155.0/207.5) X 0.50 M = 0.37 M

Nuclear Fission
Nuclear fission, subdivision of a heavy atomic nucleus, such as that of uranium or plutonium, into two fragments of roughly equal mass. The process is accompanied by the release of a large amount of energy. In nuclear fission the nucleus of an atom breaks up into two lighter nuclei.
Nuclear fission is a process where the nucleus of an atom is split into two or more smaller nuclei, known as fission products. The fission of heavy elements is an exothermic reaction, and huge amounts of energy are released in the process.
