Answer:
part (a) was used to calculate the molar mass of the metal M. In part (c) students proposed an experimental test that could be used to determine if MI 2 is an ionic solid, and then explained how the results of the test supported this claim. Students explained why I 2 is solid at room temperature, but Br 2 is a liquid in part (d). its {c}
<h3><u>Answer;</u></h3>
10 ft
<h3><u>Explanation;</u></h3>
The wave base of a wave is the depth at which there is no more perturbation of the medium caused by the wave. The wave base of a wave is determined to be half the wavelength of the wave itself.
Therefore;
Wave base = wavelength/2
= 20 ft/2
<u> = 10 ft</u>
C. water, because H2O is certain, and all those other things vary with location and climate

Answer:
entropy of reaction = 572-718= -146J/mol-k.
Explanation:
entropy of a reaction = entropy of product - entropy of reactant.
entropy of product = 2×entropy of SO2+2×entropy of NiO
=
=572 J/mol-k
entropy of reactant = 2×entropy if NiS+3×entropy of O2
=
=718 J/mol-k
therefore entropy of reaction = 572-718= -146J/mol-k.
