A kelp forest is an ecosystem in itself. Many animals use these massive forests to shelter their young from predators. Other animals feed off of the kelp plants. When you understand how marine life lives with the kelp forests you can begin to understand the big picture.
Hello,
Aluminium is a metal with 13 as its atomic number, in such a way, one could foresee the Lewis structure via its electron configuration:
Al^{13}: 1s^22s^22p^63s^23p^1
It is seen that in its last level, 3, there are three electrons, two from 3s^2 and one from 3p^1, in such a way one states that aluminium has three valence electrons which are equal to the electrons at its outer shell. The Lewis representation for aluminium is shown on the attached picture.

Answer:
Pressure, P = 15.4 lb/in²
Explanation:
Given that,
Force applied, F = 26.4 lb
Area of cross section, A = 1.71 in²
To find,
Pressure.
Solution,
Pressure is equal to force per unit area of cross section.
![P=\dfrac{F}{A}\\\\P=\dfrac{26.4\ lb}{1.71\ in^2}\\\\P=15.43\ lb/in^2\\\\P=15.43\ Pa](https://tex.z-dn.net/?f=P%3D%5Cdfrac%7BF%7D%7BA%7D%5C%5C%5C%5CP%3D%5Cdfrac%7B26.4%5C%20lb%7D%7B1.71%5C%20in%5E2%7D%5C%5C%5C%5CP%3D15.43%5C%20lb%2Fin%5E2%5C%5C%5C%5CP%3D15.43%5C%20Pa)
Hence, the correct option is (a) "15.4 lb/in²".
The correct answer should be D. can be real or virtual depending on the object's placement
Depending on the position on the mirror, it can be determined whether the object is real or virtual.
<u>Given:</u>
Volume of HCl (VHCl) = 25,0 ml = 0.025 L
Volume of NaOH (VNaOH) = 22.15 ml = 0.02215 L
Molarity of NaOH (MNaOH) = 0.155 M
<u>To determine:</u>
Molarity of HCl
<u>Explanation:</u>
Titration reaction-
HCl + NaOH → NaCl + H2O
Based on the reaction stoichiometry:
1 mole NaOH requires 1 mole HCl
# moles of NaOH = VNaOH * MNaOH = 0.02215*0.155 = 0.003433 moles
# moles of HCl = # moles of NaOH = 0.003433 moles
Molarity of NaOH = 0.003433/0.025 = 0.137 M
