SIZIF [17.4K]

Answer:

Given the following list of densities, which materials would float in a molten vat of lead provided that they do not themselves melt?

Densities (g/mL): lead = 11.4, glass = 2.6, gold = 19.3, charcoal = 0.57, platinum = 21.4.

glass and charcoal

Explanation:

The density of molten lead is about 10.65Kg/m^3

By Archimedes principles, the buoyancy of an object in a fluid is proportional to the mass of fluid displaced

which in turn is proportional to the object's density

Generally an object well float when placed on a denser medium

glass =2.6, and charcoal =0.57 are both less dense so they will float on Lead

Determine the number of bonding electrons and the number of nonbonding electrons in the structure of SI2. Enter the number of bo
mariarad [96]

Answer:

4, 16,

Explanation:

SI2 is sulphur diiodide. Sulphur is in group sixteen (six valence electrons) while iodine is in group 17(seven valence electrons).

Since there are two iodine atoms and one sulphur atom, the molecule has twenty valence electrons. Out of these twenty valence electrons, only four are bonding electrons. The other sixteen electrons include the four nonbonding electrons found on sulphur and the twelve non bonding electrons found on the two iodine atoms having six nonbonding electrons each.
