Question 2: Trends on the Periodic Table

Chemistry
1 answer:
garri49 [273]3 years ago
5 0

Answer:

In general, atomic radius decreases across a period and increases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant. ... Down a group, the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital.

Mice21 [21]

Ecologists use food web diagrams as tools in their studies of different populations of organisms within an ecosystem because it shows the feeding relationship between organisms in the ecosystem.

<h3>What is a Food web?</h3>

This is defined as the graphical representation of the feeding relationship which occurs between organisms in the ecosystem and helps to predict the outcome in the addition or removal of a species.

The food web also helps to determine the various ways in which energy flows and it usually starts from the producers which are the plants as a result of their photosynthetic ability which involves the conversion of solar energy to chemical energy.

There are various organisms in the ecosystem and the food web helps to provide a better understanding of their feeding habits and impact various factors will result in.

Calculate the unit cell edge length for an 87 wt% Ag- 13 wt% Pd alloy. All of the palladium is in solid solution, and the crysta
Goryan [66]

Answer:

Explanation:

   Since the crystal structure is FCC , every unit cell will have 4 atoms . If a be the edge length

average density = 4 x average atomic no / volume of unit cell x N

N is avogadro no or 6.02 x 10²³

average atomic no

= 100 / (87/107.9 +13/106.4) = 107.72

average density = 100 / (87/10.49 + 13/12.02)

= 10.667

10.667 = (4 x 107.72 )/ (a³x 6.02 x 10²³)

a³ = 4 x 107.72 / (10.667 x  6.02 x 10²³)

= 6.71 x 10⁻²³

a = 4.063 x 10⁻⁸ m
