An acidic solution of pH 5 has<br> TIMES as many hydrogen ions (H+) as does a solution of pH 6.
Artyom0805 [142]

The difference in concentration of hydrogen Ions between pH5 and pH6 is - x 10.

The pH scale is a scale or measure to find the strength of acidity or the basic nature of a solution or substance. pH 1 is acidic and pH 14 is the most basic on the scale.

  • The concentration of hydrogen ions is inversely related to its pH
  • More hydrogen ions present, the lower the pH
  • The fewer hydrogen ions, the higher the pH We know,

pH = -log(H+) then,    

=> 5 = -log (H+)

=> H+ = 10^{-5} (for pH = 5)    

=> pH = -log(H+)  

=> 6 = -log (H+)  

=> H+ = 10^{-6}  (for pH = 6)  

Thus, The substance with the lower pH (5) has 10 times as many hydrogen ions per volume of water.

How does a cell illustrate the basic concepts of life? Be specific and use at least 3 characteristics of life.
RoseWind [281]

Answer:

Explanation:

A cell as the functional and structural unit of life exhibits numerous concepts of life which include:

1. Growth; A cell is a subject to this as the growth of a cell translates to the growth of the tissue is composed of, the cell is responsible for all biochemical actions in living organisms, this growth is achieved via mitosis.

2. Reproduction: Cells also experience reproduction via meiosis, where a diploid cell divides to produce 2haploid cells an example of this is the spermatozoa.

3. Death: Cells are also subject to death, which can either be programmed (Apoptosis), or due to sickness(Necrosis). This is also found when humans die and become stiff due to rigor mortis which occurs as a result of cell death
