Measurements show that unknown x compound has the following composition:
Fudgin [204]

The empirical formula of the compound with the percent composition C 18.1%, H 2.27%, Cl 79.8% is C₂H₃Cl₃.

<h3>What is an empirical formula?</h3>

It is the minimum ratio between the elements that form a compound.

  • Step 1: Divide each percentage by the molar mass of the element.

C: 18.1/12.01 = 1.51

H: 2.27/1.01 = 2.25

Cl: 79.8/35.45 = 2.25

  • Step 2: Divide all the numbers by the smallest one.

C; 1.51/1.51 = 1

H: 2.25/1.51 ≈ 1.5

Cl: 2.25/1.51 ≈ 1.5

  • Step 3: Multiply all the numbers by 2 so all of them are whole.

C: 1 × 2 = 2

H: 1.5 × 2 = 3

Cl: 1.5 × 2 = 3

The empirical formula is C₂H₃Cl₃.

The empirical formula of the compound with the percent composition C 18.1%, H 2.27%, Cl 79.8% is C₂H₃Cl₃.

Plants are responsibe for a very important energy transformation what answer
Soloha48 [4]

Plants are chlorophyll-containing photosynthetic organisms. Thus, they convert solar or radiant energy into chemical energy under the process termed as photosynthesis.

<u>Explanation:</u>

  • Plants are chlorophyll-containing photosynthetic living beings. Consequently, they convert radiant energy into chemical energy under the procedure named  photosynthesis.  
  • Except for remote ocean hydro-thermal environment, the sun is the only source for all biological systems on earth. Plants catch just 2-10 percent of the solar radiation and transmit it as chemical energy. All creatures are reliant for their nourishment on producers (plants), either directly or indirectly. So there is a stream of energy from the sun (radiant energy) to producers and then to consumers (chemical energy).
