<span>It rises confidence for the reason that the more times you conduct the similar experiment over and over should either demonstrate your hypothesis right and wrong and remove any random incidences that might touch your results. Meaning it permits to have a more accurate measure or conclusion.</span>
Since the configuration contains the number 2s and 2p, you can assume that it is in period 2 of the periodic table. By noble gas shorthand, you start with helium, which is atomic number 2. 2s²2p^4 has 2+4 = 6 valence
Add 2+6 = 8, which is Oxygen.
pH can be defined as negative logarithm of hydronium ion concentration .
pH can be mathematical represented as :
pH =-log [H+]
[H+]=2.3*10^-9
pH= -log[2.3*10^-9]
=8.64
<h3><u>Answer;</u></h3>
Surface fire
<h3><u>Explanation;</u></h3>
- <u>Surface fires are type of forest fires that may burn primarily as a surface fire,</u> spreading along the ground as the surface litter and undergrowth on the forest floor and is engulfed by the spreading flames.
- They are the easiest fires to put out and cause the least damage to the forest. Surface fires create the least amount of destruction.
- <em><u>These fires protects the forest by releasing the nutrients that would otherwise decompose slowly, having little benefit to the ecosystem.</u></em>
- <em><u>Additionally, these fires allow more open spaces for new and different kinds of vegetation to grow and receive sunlight.</u></em>
