The student finds the following particulate model of AgCl(s). Assuming the crystal structures are similar, how should the student modify the model to represent CuCl(s)? Justify your answer in terms of the radius and arrangement of electrons in the ions

Group the following  ions into one of two groups based on the ion size compared to itsrespective neutral parent atom: (1) larger ionic radiusthan neutral atom OR (2)smaller ionic radiusthan neutral atom. Ions - Li, Be, N, O, F, Na, Mg, Al, P, S, Cl, K, Ca   Explain BOTH of the two groupings based on the principles of attractive/repulsive forces between theelectron(s) and proton(s) and how those forces affect the distance between the nucleus and atom’s vsion’s valence electrons.

Understanding electrostatic forces. Choose where the object outlined in green will go based on the charges.

The energy for the following reaction was measured to be -653.0 kJ/mol. K(g) + Cl(g) → KCl(s). Using this fact and data in the table below, calculate the enthalpy (in kJ/mol) required to separate the ions from the lattice for this reaction: KCl(s) → K⁺(g) + Cl⁻(g).

Identifying hydrogen-bonding interactions between molecules.

Hydrogen cyanide (HCN) is a colorless gas. It is poisonous and smells like almonds. Draw a Lewis structure for this compound, explain why you drew the Lewis structure the way that you did, and predict the shape of the molecule.

I have to fill out this graph but I'm not sure how to.   The options are for the blanks are: Linear (AX2), Trigonal Planar (AX3), Bent (AX2E), tetrahedral (AX4), Trig pyramidal (AX3E), Trig bipyramidal (AX5), SeeSaw (AX4E), T-shaped (AX3E2), square pyramidal (AX5E), square planar (AX4E2), 180, 120, <120, 109.5, 90 and 120, <90 and <120, <90, 90, <180

Why is salt, NaCl, relatively harmless even though the elements that compose it, sodium, and chloride, are toxic?

Based on the bond energies for the reaction below, what is the enthalpy of the reaction? HC≡CH (g) + 5/2 O₂ (g) → 2 CO₂ (g) + H₂O (g)

why are some gases polar molecules? For example, SO2 is a polar molecule and a gas. CHCl3 is a polar molecule but a liquid. How come these two examples are both polar molecules but are in different states of matter?
