D. 2Fe2O3

Explanation:

The most likely product of this reaction is  Fe₂O₃. This product is the only one out of the given options that contains both combining species.

In a chemical reaction, the mass and matter is conserved. According to the law of conservation of mass "in a chemical reaction matter is neither created nor destroyed".

Through this, we know that chemical reactions are just rearrangement of species.

The kind of reaction given above is a synthesis or combination reaction in which two species comes together to give products.

                        4Fe + 3O₂ ⇒ 2Fe₂O₃

The atoms and number of moles are all balanced.

A popular car has a gas tank that holds a maximum of 14.5 gallons of fuel. What is
gulaghasi [49]

Taking into account the change of units, the size of the tank is 54.88 liters.

In first place, the rule of three is a tool used to quickly solve problems involving a proportional relationship between two variables.

The rule of three is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.

If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other), the direct rule of three should be applied.

The rule of three is applied as follows, with A, B and C being known values ​​and D being an unknown value: if A maintains a certain relationship with B, and it is known that C and D have the same relationship, it is possible to calculate the unknown value D using the following expression:

D=\frac{CxB}{A}

In this case, the rule of three can be applied as follows: if 1 gallon is equal to 3.785 liters, 14.5 gallons are equal to how many liters?

D=\frac{14.5 gallonsx3.785 liters}{1 gallon}

Solving:

D= 54.88 liters

In summary, the size of the tank is 54.88 liters.

Each energy sublevel contains __________ number of electrons. For example, sublevel D can hold up to _______ electrons. A. the s
Annette [7]

Answer:

Each energy sublevel contains a different number of electrons. For example, sublevel D can contain up to 10 electrons

Explanation:

The atoms are surrounded by propellers that within each propeller there is a certain number of electrons, these electrons jump from orbit to orbit according to the amount of energy they have. The four levels that make up the electronic cloud that surrounds an atom are: s p d f.

When these electrons change orbit or level they release energy in the form of light, which is known as a photon.
