Which type of mixture can be separated using a sieve?

DaniilM [7]

FILTRATION When the substances in a mixture have different particle sizes, they are separated by filtration. The mixture is poured through a sieve or filter. The smaller particles slip through the holes, but the larger particles do not.p

When you have a free metal ion, how do the energies of these orbitals relate to one another (are they the same, different, etc.)

7nadin3 [17]

Answer:

The energy of the orbitals are the same

Explanation:

For a free metal ion, all the d-orbitals are of the same energy. The five d-orbitals are said to be five fold degenerate in the free metal ion. Hence all the d-orbitals will possess the same energy irrespective of which one is first filled.

In an octahedral or tetrahedral crystal field, the d-orbitals will loose their degeneracy and become different in energy based on their orientation towards the ligands.

The mass defect for the formation of lithium-6 is 0.0343 g/mol. The binding energy for lithium-6 nuclei is ________ kJ/mol. Ente

Sholpan [36]

<u>Answer:</u> The binding energy for lithium-6 nuclei is 3.09 E+11

<u>Explanation:</u>

Binding energy is defined as the energy which holds the nucleus together. It is basically the product of mass defect and the square of the speed of light.

This energy is calculated by using Einstein's equation, which is:

$E=\Delta mc^2$

where,

E = Binding energy of the atom

$Delta m$ = Mass defect = 0.0343g/mol = $0.0343\times 10^{-3}kg/mol$ (Conversion factor: $1kg=10^3g$ )

c = speed of light = $3\times 10^8m/s$

Putting values in above equation, we get:

$E=0.0343\times 10^{-3}kg/mol\times (3\times 10^8m/s)^2$

$E=3.09\times 10^{14}J/mol=3.09\times 10^{11}kJ/mol$ (Conversion factor: $1kJ=10^3J$ )

Hence, the binding energy for lithium-6 nuclei is 3.09 E+11

Pavlova-9 [17]

Iron metal has a sea of electrons feature. The outside electrons form a sea or pool of delocalized electrons that are free to travel randomly throughout the fixed lattice of positive ions and do not "belong" to any particular atom.

<h3>What is iron metal?</h3>

On the Periodic Table of the Elements, iron is a metal that belongs to Group 8 and is a hard, brittle substance. The most common metal, it is pure form, corrodes quickly when exposed into humid air and high temperatures. Iron is also considered to make up a significant portion of the Earth's core and is the fourth most prevalent metal by weight in the Earth's crust. According to the Los Alamos National Laboratory, it is abundant in the sun and stars in addition to being widely distributed on Earth. According to Jefferson Lab, iron is essential for the survival of all living things.
