Explain why the pbcl2 dissolved when water was added
lara [203]

PbCl2 would not dissolve because it is insoluble based on the solubility rules for substances that will dissolve in water. This compound would instead form a solid precipitate at the bottom of the container.

We divide the electromagnetic spectrum into six major categories of light, listed below. Rank these forms of light from left to
Kazeer [188]

Explanation:

The electromagnetic spectrum shows the wavelength or frequency range of different waves starting from gamma rays to radio waves.

In the electromagnetic spectrum, gamma rays have shorter wavelength while radio wave have longest wavelength.

The correct order is as follows :

(A) Gamma rays

(B) X rays

(C) Ultraviolet

(D) Visible light

(E) Infrared waves

(F) Radio waves

So, the correct order form left to right in order of increasing wavelength is as follows :

Gamma rays < X rays < Ultraviolet < Visible Light < Infrared Waves < Radio Waves

The relationship between the molar concentration of silver ion in a saturated solution of silver phosphate and the solubility pr
kondor19780726 [428]

Answer: The solubility product of Ag_3PO_4 is 27s^4

Explanation:

Solubility product is defined as the equilibrium constant in which a solid ionic compound is dissolved to produce its ions in solution. It is represented as K_{sp}

Ag_3PO_4\leftrightharpoons 3Ag^++PO_4^{3-}

We are given:

Solubility of Ag_3PO_4 = S mol/L

By stoichiometry of the reaction:

1 mole of Ag_3PO_4 gives 3 moles of Ag^{+} and 1 mole of PO_4^{3-}.

When the solubility of Ag_3PO_4  is S moles/liter, then the solubility of Ag^{+} will be 3S moles\liter and solubility of PO_4^{3-} will be S moles/liter.

Expression for the equilibrium constant of Ag_2CrO_4 will be:

K_{sp}=[Ag^+]^3[PO_4^{3-}]

K_{sp}=[3s]^3[s]=27s^4

The solubility product of Ag_3PO_4 is 27s^4

How many grams of glucose are in 175 mL of a 5.50% (m/v) glucose solution?
puteri [66]
<span>1. 5.50% m/v means that the solution contains 5.50% of the volume measured in grams

so in 165mL you will have 5.5%*165 = 9.075g

2. 18.5% v/v means 18.5% of the total volume is methyl alcohol

so in 1.87L you will have 18.5%*1.87 = 0.35L of methyl alcohol.

3. This one works backwards. If 32.1 g is 6.00%, what is 100%?

100% = 32.1/0.06 = 535 mL </span>
