Acompound contains carbon, hydrogen, and nitrogen as its only elements. a 9.353 g sample of the compound contains 5.217 g of carbon and 1.095 g of hydrogen; the remainder is nitrogen. what is the empirical formula for the compound?

Empirical formular is given as ; C₂H₅N

Explanation:

Information given;

Mass of sample = 9.353g

Mass of Carbon = 5.217g

Mass of Hydrogen = 1.095g

Remainder is Nitrogen.

Mass of Nitrogen = Mass of Sample - (Mass of carbon + Hydrogen)

Mass of Nitrogen = 9.353 - (5.217 + 1.095) = 3.041g

Step 1: Determine the masses. We just calculated the value for this.

Step 2: Determine the number of moles by dividing the grams by the atomic mass.

Carbon = 5.217/12 = 0.4348

Hydrogen = 1.095/1 = 1.095

Nitrogen = 3.041/14 = 0.2172

Step 3: Divide the number of moles of each element by the smallest number of moles.

The smallest in this case is 0.2172

Carbon = 0.4348/ 0.2172 = 2.044

Hydrogen = 1.095/ 0.2172 = 5.14

Nitrogen = 0.2172/ 0.2172 = 1

Step 4: Convert numbers to whole numbers

Carbon = 2.044 = 2

Hydrogen = 5.14 = 5

Nitrogen = 1 = 1

Empirical formular is given as ; C₂H₅N

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

assuming that your periodic table has eighteen columns, you should highlight   the four elements in the third column from the left of the table.

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the have energy higher than those in the orbital while lower than those of the orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the orbital is therefore filled right after orbitals and before orbitals.  

potassium has electron configuration and calcium . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the and should be highlighted as well.
