Answer:

                      Empirical Formula  =  C₁H₄ or CH₄

Explanation:

Data Given:

                     Mass of C  =  12.0 g  

                     Mass of H  =  4 g  

Step 1: <u>Calculate Moles of each Element;</u>

                     Moles of C  =  Mass of C ÷ At.Mass of C

                     Moles of C  = 12.0 ÷ 12.0

                     Moles of C  =  1.0 mol

                     Moles of H  =  Mass of H ÷ At.Mass of H

                     Moles of H  = 4.0 ÷ 1.0

                     Moles of H  =  4.0 mol

                     Moles of O  =  %O ÷ At.Mass of O

                     Moles of O  = 53.924 ÷ 16.0

                     Moles of O  =  3.370 mol

Step 2: <u>Find out mole ratio and simplify it;</u>

                             C                                                     H                                

                            1.0                                                   4.0                              

                         1.0/1.0                                             4.0/1.0                    

                              1                                                      4                  

Hence,

              Empirical Formula  =  C₁H₄ or CH₄

The moving of molecules from areas of high concentration to that of low concentration to gain energy is best described as
seropon [69]

The moving of molecules from areas of high concentration to that of low concentration to gain energy is best described as passive transport

<h3>What is passive transport?</h3>

Passive transport is a type of membrane transport in which chemicals are moved across cell membranes without using energy. Unlike active transport, which uses cellular energy, passive transport uses the second law of thermodynamics to cause the movement of substances across cell membranes.

<h3>Why is passive transport important?</h3>

Passive transport processes are critical to homeostasis. They maintain proper conditions inside the cell and the organism as a whole by letting chemicals to pass into and out of the cell.
