Answer:
The Beer–Lambert law, also known as Beer's law, the Lambert–Beer law, or the Beer–Lambert–Bouguer law relates the attenuation of light to the properties of the material through which the light is travelling.

True. Any cosmetic containing paraffin wax, benzene, mineral oil, PEG, DEA, MEA, the suffix ethyl- or propyl-, etc. About 95% of fragrances contain petrochemicals.
Answer:
An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision (Figure. 17.5 “Temperature and Reaction Rate”).
Explanation:
The reaction is not at equilibrium because Q >P hence the reaction moves towards the left hand side.
<h3>What is the equilibrium constant?</h3>
The equilibrium constant is a figure that tells us the extent to which the reactants have been converted to products in a reaction.
Now we have the reaction; PCl3(g) + Cl2(g) ⇄ PCl5(g) hence we can write;
Q = [PCl5]/[PCl3] [Cl2]
Q = 0.39/0.21 * 0.41
Q = 4.5
The reaction is not at equilibrium because Q >P hence the reaction moves towards the left hand side.

Answer:
zero
Explanation:
In a unit cell, an atom that is located at the center of a cube edge is not involved in sharing unit cells because a central atom of a unit cell belongs to the entire cell and only to that unit cell of the lattice.
Hence, the center atom of a unit cell do not share any unit cell and the correct answer is "Zero".
