Rusting is a very expensive process to humans and is represented by the simplified equation of: 4Fe + 3O₂ → 2Fe₂O₃ .
At the basic level, rust occurs when iron comes into contact with air (oxygen) and they both react to form Iron Oxide which is the chemical name for rust.
The equation is:
Iron + Oxygen → Iron Oxide
4Fe + 3O₂ → 2Fe₂O₃
In conclusion, the simplified equation for rust is 4Fe + 3O₂ → 2Fe₂O₃.

What is the chemical formula for nickel (III) oxide? NiO Ni3O NiO3 Ni2O3
The chemical formula for Nickel (III) oxide is [tex]Ni_{2}O_{3}[/tex].
Given data:
The chemical formula for nickel (III) oxide is [tex]Ni_{2}O_{3}[/tex]. This formula indicates that each molecule of nickel (III) oxide consists of two nickel (Ni) atoms and three oxygen (O) atoms.
Nickel is in its +3 oxidation state. The oxidation state represents the charge of the element in the compound, and in nickel (III) oxide, each nickel atom carries a +3 charge.
The presence of three oxygen atoms in the compound is indicated by the subscript 3 after the O in the formula. This means that there are three oxygen atoms for every two nickel atoms in the compound.
Hence, the chemical formula [tex]Ni_{2}O_{3}[/tex] represents nickel (III) oxide.

Answer: The values for the constants are c=2, and d=-4.
explanation: We have the function f, defined as:
and
where c and d are constants.
So, if f is differentiable at x=2, then it must be continuos at x=2, therefore
Let's call this, equation 1.
On the other hand, we have that f is differentiable, therefore
and
so, we calculate
which, replacing in equation 1, gives us
Finally, the answer is that c=2, and d=-4.
The constants have the values c=2 and d=-4.
What is constants?A constant is an identifier (name) for a simple value. As the name suggests, that value cannot change during the execution of the script (except for magic constants, which aren't actually constants). Constants are case-sensitive.
A constant in computer programming is a value that should not be changed by the program while it is running normally, i.e., the value is constant.

Answer:
I put 7 but im not sure if it correct yet
Explanation:
if point U is on RS but the U to P is 7 units then U must be the midpoint of RS but i have no idea hope this helps
The correct answer in the box is 7. If the length of UP is 7 units, the length of UQ is 7 units.
What is a fraction?A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
Every point on the PQ perpendicular bisector, which can be used to define it, has the same distance from P and Q. This is one of its characteristics.
The following provides evidence for this: Think about the shape created if we connect U, P, and Q. PTU and QTU are the two triangles present. Since T is the midway and the leg UT is common, we know that the two T angles are 90 degrees and that PT=TQ. The triangles are equal as a result of side-angle-side, hence UP=UQ.
Therefore, If the length of UP is 7 units, the length of UQ is 7 units.
