David observed properties of four different compounds, only one of which is an ionic compound. His observations are shown in the chart. A 2-column table with 4 rows. The first column labeled compound has entries W, X, Y, Z. The second column labeled observations has entries is a hard solid, melts at 44 degrees C, has a molecular structure; is a brittle solid, does not conduct electricity in water, has a crystal structure; is a hard solid, conducts electricity, has a molecular structure; is a brittle solid, melts at 801 degrees C, has a crystal structure. Which is most likely the ionic compound? W X Y Z

Z

Explanation:

As we know, ionic compounds are characterized by its brittle and hard nature.  Such compounds possess extremely high boiling, as well as, melting points and therefore, more conducive. As per the question, 'Z' is most likely the ionic compound because it possesses the above characteristics of being large in mechanical force(brittle solid, melts at 801 degrees C, has a crystal structure). Thus, option D i.e. 'Z' is the correct answer.

predicting long term climate trends reliably is much easier than predicting short term weather, owing to the different data sets used for each.
