The dilution factor of the unknown sample is 10. The dilution factor of a solution refers to the ratio of the final volume of the now diluted solution to the initial volume of the of the initial concentrated solution.

Mathematically;

The dilution factor is given by the formula;

Dilution factor = Final volume of the now diluted solution/ Initial volume of more concentrated solution

Final volume of the now diluted solution = 100.0 ml

Initial volume of more concentrated solution = 10.00 ml

Dilution factor = 100.0 ml/10.00 ml

Dilution factor =  10

What is the mole ratio between CuCl2 and NaNO3?
kherson [118]

Answer:

Explanation:

If this is a double replacement reaction or salt metathesis, then I have taken the liberty of including the symbol representing an aqueous solution, (aq), to the formulas in the equation written as CuCl2(aq)+2NaNO3(aq)→Cu(NO3)2(aq)+2NaCl(aq).

In order for a double replacement reaction to occur, one of the products must be a solid precipitate (a salt), an insoluble gas, or water. Since all species are in aqueous solution, none of these products occur, which means there is no reaction. The result is an aqueous solution containing Cu2+, Cl−, Na+, and NO3− ions.

The equation should be written as CuCl2(aq)+2NaNO3(aq)→No Reaction

The typical silver salt used in ordinary photographic films is silver bromide, AgBr. The minimum amount of energy needed to init
Leya [2.2K]

Answer:

4.95×10^-7 m

Explanation:

E= hc/λmax

λmax= hc/E

Where :

h= 6.6×10^-34 Js

c= 3×10^8ms-1

E= 4.00×10−19 J

λmax=6.6×10^-34 × 3×10^8/ 4.00×10^-19

λmax=4.95×10^-7 m

Note:

h= planks constant

c= speed of light

E= energy of the photon

λmax= maximum wavelength of the photon.

Select the term that matches each definition:
Zinaida [17]

Answer:

a) common ion effect

b) solubility

c) saturated solution

d) solubility product constant

e) molar solubility

Explanation:

When a substance, say BA2 is dissolved in a solution and another substance CA2 is dissolved in the same solution. The solubility of BA2 is decreased due to the addition of CA2. This is known as common ion effect.

The mass of a substance that will dissolve in a given Volume of solvent is known as it's solubility.

The molar solubility is the amount of moles of solvent that dissolves in 1 dm^3 of solvent.

A solution that contains just as much solute as it can normally hold at a given temperature is known as a saturated solution.

Lastly, the product of molar solubilites raised to the power of the molar coefficient is know as the solubility product constant.

What term is used to label the energy levels of electrons?
Natalka [10]
The term that is used to label the energy levels of electrons are principle quantum numbers and a valance band refers to the “energy levels in an atom where the electrons that participate in bonding occupy. These energy levels correspond to those of the s and p orbitals of the outermost shell of the atom being considered.” Hope this helps! :)
