Explanation:Switching off lights when not in use protects environmental quality.
<span>As salma views a famous impressionist painting that is hung on a wall, her RETINAS receive visual information about the art and carry this information to her brain. At the back of each eye, the retina is a thin sheet of tissue containing several types of cells. The photoreceptor cells in the retina first transform light energy into electrical current. The last processing step in the retina is the activity of neurons calls retinal ganglion cells. The ganglion cells send electrical impulses along their axons, which form the optic nerve that travels into the brain.</span>
Answer:
The answer is B. Van der Waals forces are weaker than ionic and covalent bonds.
Explanation:
In general, if we arrange these molecular forces from the <u>strongest to weakest</u>, it would be like this:
<h3>Covalent bonds > Ionic bonds > Hydrogen bonds > Dipole-Dipole Interactions > Van der Waals forces</h3><h3 />
Covalent bonds are known to have the strongest and most stable bonds since they go deep and into the inter-molecular state. A diamond is an example of a compound with this characteristic bond.
Ionic bonds are the next strongest molecular bond following covalent bonds. This is due to the <u>protons and electrons causing an electro-static force</u> which results to the strong bonds. An example would be <em>Sodium Chloride (NaCl)</em>, which when separated is <em>Na⁺</em> and <em>Cl⁻</em>.
Van der Waals forces, also known as Dispersion forces, are the weakest type of molecular bonds. They are only formed through <u>residual molecular attractions when molecules pass by each other.</u> It doesn't even last long due to the <u>uneven electron dispersion</u>. It can be made <u>stronger by adding more electrons in the molecule</u>. This kind of molecular bonds appear in <em>non-polar molecules</em> such as <em>carbon dioxide</em>.
