Answer/Explanation:

18, a,

I believe the n, and s represents North, South, or just the way the arrows are rotating repeatedly.

18, b,

The phenomenon re-occurring shows the alignment of magnetic dipoles with in a magnet, like inside. The arrows show a direction in the line with an external magnetic field in a way that it can produce its own magnetic fields that seem to travel from North to the South.

18, c,

Incorrect. Refrigerator magnets have multiple layers of magnification, they use opposite polarities to stay this way. If he puts the magnet sideways it may stick to the fridge

How molecules react to an increase in temperature.
Slav-nsk [51]

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”).

What is the numerical value for Q for this reaction? Remember to always express your answer to correct number of significant fig
ioda

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.

How many unit cells share an atom that is located at the center of a cube edge of a unit cell?
andre [41]

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".
