Students are almost finished with their investigation of compound properties. As shown in the table below, the only step they have yet to complete is to decide whether HCl is ionic or covalent. Compound/ Formula Melting/ Point Boiling/ Point Conductive in Solution? Ionic or cov

CCl4 /-23°C /77°C/ No/ Covalent

MgO /2852°C /3600°C /Yes /Ionic

HCl /-85°C /-114°C /Yes

KBr /734°C /435°C /Yes /Ionic

Select which statement correctly completes the table and contains a correct conclusion based on the information in the above table.

A.
HCl is an ionic compound. This table demonstrates that ionic compounds have much higher melting and boiling points than covalent compounds.

B.
HCl is a covalent compound. This table demonstrates that ionic compounds are electrically conductive in solution while covalent compounds are not.

C.
HCl is an ionic compound. This table demonstrates that ionic compounds are electrically conductive in solution while covalent compounds are not.

D.
HCl is a covalent compound. This table demonstrates that ionic compounds have much higher melting and boiling points than covalent compounds.

Consider the particle-in-a-box problem in 1d. a particle with mass m is confined to move freely between two hard walls situated at x = 0 and x = l. the potential energy function is given as (a) describe the boundary conditions that must be satisfied by the wavefunctions ψ(x) (such as energy eigenfunctions). (b) solve the schr¨odinger’s equation and by using the boundary conditions of part (a) find all energy eigenfunctions, ψn(x), and the corresponding energies, en. (c) what are the allowed values of the quantum number n above? how did you decide on that? (d) what is the de broglie wavelength for the ground state? (e) sketch a plot of the lowest 3 levels’ wavefunctions (ψn(x) vs x). don’t forget to mark the positions of the walls on the graphs. (f) in a transition between the energy levels above, which transition produces the longest wavelength λ for the emitted photon? what is the corresponding wavele

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
