lora16 [44]3 years ago
7 0
An important information or constant to recall here is the Avogadros constant. This will help us solve how many moles are there from the number of atoms given. These is how we proceed: 1.773x10^ {17}*  \frac{ mol}{6.02*10^{23}} *  \frac{1 mole Na2CO3}{1 moleC}*  \frac{105.98g Na2CO3}{mol}  = 3.12 * 10^{-5}

Answer: <span>3.12 * 10^{-5} </span><span>grams of Sodium carbonate (Na2CO3) </span>

A solution contains one or more of the following ions: Ag , Ca2 , and Co2 . Lithium bromide is added to the solution and no prec
koban [17]

Answer:

Ca^{2+}  and  Co^{2+}

Explanation:

Given:

A solution contains one or more of the following ions such as Ag, Ca_2 and Co_2

Here the Lithium bromide is added to the solution and no precipitate forms

Solution:

Since with LiBr no precipitation takes place therefore Ag+ is absent

Here on adding Li_2SO_4 to it precipitation takes place.

Precipitate is as follows,

Ca^{2+}(aq)+SO_4^2^-(aq)----->CASO_4(s)

Thus,

Ca^2^+ is present

When Li_3PO_4 is added again precipitation takes place.

Therefore the reaction is as follows,

Co^2^+(aq)+PO_4^3^-(aq)------>Co_3(PO_4)_2(s)

Therefore,

Ca^{2+}  and  Co^{2+} are present in the solution

In what specific situations would you use a light microscope? an electron<br>microscope?​
galina1969 [7]

ANSWER

A standard light microscope is used to view living organisms with little contrast to distinguish them from the background, which would be harder to see with the electron microscope.

Electron microscopes can be used to examine not just whole cells, but also the subcellular structures and compartments within them.

How do ionic bonds affect the properties of ionic compounds?
Deffense [45]

Answer:

The bonds prevent ions from moving throughout the crystal, so a solid ionic compound is a poor conductor.

Explanation:

Ionic bonds are those bonds that form between the ions of molecules. It is formed as a result of electrostatic attraction between the molecules or compounds. The ionic bonds that forms between ionic compounds are responsible for certain properties exhibited by them.

Ionic bonds hold the molecules of ionic compounds so tightly that it prevent ions from moving throughout the crystal, hence, a solid ionic compound is a poor conductor of heat and electricity.
