Based on the Hund's Rule, the three electrons in a 2p orbital are arranged as shown in option C.

<h3>What is an orbital?</h3>

The term orbital refers to a region in space where there is a high probability of finding the electron. We know that an electron in an atom could be defined by the use of four sets of quantum numbers which are;

The principal quantum number
The orbital quantum number
The spin quantum number
The magnetic quantum number

Hund's rule states that, electrons occur singly before pairing takes place. In this case, we can see that the only arrangement that obeys the Hund's Rule is option C.

Help on science please !!

NemiM [27]

Answer:

a. Kenya's growth seems to be a large population influx, an increase in the pre-reproductive stage.

b. There is a decrease in the younger generation, meaning that the reproductive part of the population is more than the pre-reproductive part. Which means less of an incline in population.

c. You can see the differences within the countries, that the growth rate in Kenya is extremely high, the United States more moderate, while Germany is somewhat even throughout. Germany is not growing much in comparison to Kenya.

Please help. What is the empirical formula mass for C4H12O4?

just olya [345]

61g/mol

Explanation:

The empirical formula of compound is its simplest formula. It shows the simplest ratio by which the atoms are combined.

In the formula C₄H₁₀O₄

we have:

4 moles of carbon 10 moles of hydrogen 4 moles of Oxygen;

4 : 10 : 4

The simplest ratio can be obtained by dividing through by the highest common factor which is 2;

4/2 10/2 4/2

2 5 2

the empirical formula is C₂H₅O₂

The formula mass is the sum of the atomic weights;

C₂H₅O₂ = (2 x 12) + (5x1) + (2x 16) = 24 + 5 + 32 = 61g/mol

How do you balance a chemical equation

Dominik [7]

There should be mass balance and the charge balance between the reactants and the products

Mass balance : total no of individual atoms of each type should be balanced before and after the reaction

Charge balance : Overall charge of the reactants should be balanced with the overall charge of the products

You can balance,

1)by just looking at it

2)by Algebraic method given above or

3)by the redox method

You need to know how to get the oxidation numbers in order to use the oxidation method
