An ingot of elemental silver will have a silvery-white color. In fact silver is said to be the "whitest" of all metals. If it is to be grind , the silver up into smaller and smaller particles, the silver will appear progressively grayer or darker. This is because smaller particles become less effective at reflecting light and produce more scattering

The color of the element silver that occurs in nature is gray. Sometimes it is described to have a color of white and is said to be the most white among the metals. However, smaller pieces of this element would look darker because it will not reflect light that much.

A mixture of so2(g) and o2(g), formed by the complete decomposition of so3(g), is collected over water at 34°c at a total pressu

Sedbober [7]

The decomposition of so3 to so2 gas and o2 gas can be described in the balanced chemical equation:

2so3(g) = 2 so2 (g) + 02(g).

so assuming a complete reaction, the ratio of so2 gas to total products is 2/3 while that of 02 is 1/3.

Subtracting water's water vapor pressure, 760-40 mm hG = 720 mm Hg.

then the products partial pressures are

so2 = 2/3 * (720) = 480 mm Hg.
o2 = 720-480 = 240 mm Hg.

Answer: The equilibrium constant for the above reaction is 1.31

Explanation:

We are given:

Initial moles of nitrogen gas = 0.3411 moles

Initial moles of hydrogen gas = 1.661 moles

Equilibrium moles of nitrogen gas = 0.2001 moles

For the given chemical reaction:

$N_2(g)+3H_2(g)\rightleftharpoons 2NH_3(g)$
