Answer: It dissolves a variety of solutes in it.

Explanation: Water is capable of dissolving a variety of solutes in it so called as universal solvent.

It has the ability to dissolve solutes more than any other liquid. It is a very essential component of earth because water flows and carries many nutrients and minerals dissolved in it.

It is due to its chemical composition that allows it to do so.It has a polar arrangement of oxygen which provides negative charge and hydrogen molecules provides positive charge.

This provides water the ability to dissolve many solute particles in it.

Because water is able to dissolve in many things and most of this world is made out of water so no country or state doesn't have water, some have infected water with lead in them and others don't, but water can dissolve in salt, that's why they call it salt water and also tapped water where u put some mixtures in them to make it have flavor.

1. Metallic strontium crystallizes in a face-centered cubic lattice, with one Sr atom per lattice point. If the edge length of t

Zarrin [17]

Answer:

$r=215pm$

$N_{Mn}=20$

Explanation:

From the question we are told that:

Edge length of the unit cell $l=608pm$

Generally the equation for The relationship between edge length and radius is mathematically given by

$4r=\sqrt{2a}$

Therefore

$4r=\sqrt{2*608}$

$r=\frac{\sqrt{2*608}}{4}$

$r=215pm$

From the question we are told that:

Density $\rho=7.297$

Edge length of $l=630.0 pm=>630*10^-{10}$

Therefore Volume is given as

$V=l^3$

$V=630*10^-{10}^3$

$V=2.50047*10^{−22}$

Generally the equation for Mass is mathematically given by

$m=Volume*density$

$m=V*\rho$

$m=2.50047*10^{−22}*7.297$

$m=1.83*10^{-21}g$

Therefore Molarity is given as

$n=\frac{M}{Molar M}$

$n=\frac{1.83*10^{-21}g}{55}$

$n=3.32*10^{-23}$

Finally The atoms in a unit cell is

$N_{Mn}=Moles*Avogadro\ constant$

$N_{Mn}=3.32*10^{-23}*6.023*10^{23}$

$N_{Mn}=20$

What is the name of the ionic compound that contains a NA+ ion for every Cl- ion

katen-ka-za [31]

The name is sodium chloride. This is an ionic compound so you use the ionic naming system which is the name of the cation followed by the name of the anion. I hope this helps. Let me know if anything is unclear.
