Metals are good conductors of energy and heat while non metals are bad conductors of energy and heat

Metals are malleable and ductile while nonmetals are brittle

Metals are solid at room temp expect Hg which is liquid at room temp and we have non metals that’s are solid liquid and gas such as ( carbon oxygen sulfur bromine iodine )

PV = nRT
n = PV/RT
n = (.117)(3)/(.0821)(273+80)

The graph below shows the volume and the mass of four different substances at STP.
sladkih [1.3K]
The formula of density is mass / volume

This means that
- high mass, low volume = high density
- high mass, high volume = so-so
- low mass, high volume = low density

From the graph shown, 
D has the lowest density because it has low mass yet high volume.

If a solution containing 0.10 M Cl-, Br-, I-, and LaTeX: CrO_4^2-C r O 4 2 − is treated with Ag+, in what order will the anions
Musya8 [376]

Answer:

AgI \longrightarrow AgBr \longrightarrow Ag_2CrO_4 \longrightarrow AgCl

Explanation:

The first thing to have in mind is that the Ksp (constant of solubility) gives you an idea of how much soluble a salt is.  <u>If the concentration of ions of that salt exceeds the kps, the salt will precipitate</u>.

The Kps of all these salts are very small compared to the 0.1 M concentration of the anions so all of them will precipitate.

The smaller the constant, the faster the salt precipitates

Having that concept in mind, the order of precipitation from first to last would be:

AgI \longrightarrow AgBr \longrightarrow Ag_2CrO_4 \longrightarrow AgCl
