The solubility of silver(I)phosphate at a given temperature is 1.02 g/L. Calculate the Ksp at this temperature. After you get yo
Snezhnost [94]

<u>Answer:</u> The solubility product of silver (I) phosphate is 9.57\times 10^{-10}

<u>Explanation:</u>

We are given:

Solubility of silver (I) phosphate = 1.02 g/L

To convert it into molar solubility, we divide the given solubility by the molar mass of silver (I) phosphate:

Molar mass of silver (I) phosphate = 418.6 g/mol

\text{Molar solubility of silver (I) phosphate}=\frac{1.02g/L}{418.6g/mol}=2.44\times 10^{-3}mol/L

Solubility product is defined as the product of concentration of ions present in a solution each raised to the power its stoichiometric ratio.

The chemical equation for the ionization of silver (I) phosphate follows:

Ag_3PO_4(aq.)\rightleftharpoons 3Ag^{+}(aq.)+PO_4^{3-}(aq.)  

                            3s                  s

The expression of K_{sp} for above equation follows:

K_{sp}=(3s)^3\times s

We are given:  

s=2.44\times 10^{-3}M

Putting values in above expression, we get:

K_{sp}=(3\times 2.44\times 10^{-3})^3\times (2.44\times 10^{-3})\\\\K_{sp}=9.57\times 10^{-10}

Hence, the solubility product of silver (I) phosphate is 9.57\times 10^{-10}

In one or two sentences, make and justify a claim about the frequency of a wave if the wavelength increases and the velocity sta
oksian1 [2.3K]

Answer:

The relationship between the frequency of a wave and the wavelength is an inverse relationship, therefore, if the wavelength of a wave increases and the velocity of the wave stays the same, the frequency of the wave decreases.

An example is the ocean wave, if the distance between successive wave crests, which is the wavelength, 'λ', of the wave, increases, while the velocity, 'v', of the wave coming to shore remains the same, the number of wave crest arriving at the beach in a given period of time, which is the frequency of the wave, 'f',  decreases according to the following equation;

f = v/λ

Earth's atmosphere is composed mostly of nitrogen and oxygen. In order to float, a ballon has to be filled with something that i
miskamm [114]
Well the two Gases we use Are hydrogen and helium which Are both lighter than air. We know This Because it can make a ballon float Also, When you inhale helium, you're changing the type of gas molecules in your vocal tract and increasing the speed of the sound of your voice. but the vibration frequency of the vocal cords doesn't change along with the type of gas molecules that surround them. When You use the Periodic Table You look at the Numbers at the top of the element, (atomic numbers) it starts at the Number 1 the element that Weighs the lowest all the way to 118 the element that Weighs the most. If we look a hydrogen and helium on the Periodic Table Their atomic Numbers Are 1 and 2 while oxygen and nitrogen Are at 7 and 8 on the Periodic Table so hydrogen and helium Weighs less than air so it will make a ballon float
