Calculate the molar solubility of aluminum hydroxide (AlOH)3) in a 0.027M solution of aluminum nitrate (Al(NO3)3). The Ksp of AlOH)3 is 2.0x10-32.

Answers

Answer 1

Answer:

s = 5.22x10⁻⁹ M

Explanation:

Let's write the equilibrium reaction for this compound:

Al(OH)₃ <-------> Al³⁺ + 3OH⁻      Ksp = 2x10⁻³²

To get the solubility, we need to write the equilibrium expression:

Ksp = [Al³⁺] [OH⁻]³

Al(OH)₃ does not contribute to the equilibrium expression, because is a solid compound. Now, according to this, we have the following:

                   Al(OH)₃ <-------> Al³⁺ + 3OH⁻

I.                                             0          0

E.                                            s          3s

Replacing into the Ksp expression:

2x10⁻³² = (s) (3s)³

2x10⁻³² = s * 27s³

2x10⁻³² = 27s⁴

s = ⁴√2x10⁻³² / 27

s = 5.22x10⁻⁹ M

This would be the solubility of the compound.

Hope this helps

2.14g of sodium sulfide react with excess hydrochloric acid to form sodium chloride and dihydrogen sulfide.
BALANCE IT TO AN EQUATION

Answers

Answer:

2.14 Na2S + 1.99 HCl ----> 3.20 NaCl + 0.935 H2S

Explanation:

The Balanced equation is

Na2S + 2HCl = 2NaCl + H2S

As we can see -

78.0452 g/mol of sodium sulfide reacts with 2 mole of HCl.

Mass of one mole of HCl = 36.458 g/mol

So, 78.0452 g/mol of sodium sulfide reacts with 2* 36.458 g/mol of HCL to produce 2* 58.44 g of NaCl and 34.1 g/mol of H2S

Thus,

2.14g of sodium sulfide will react with (2* 36.458/78.0452)* 2.14 of HCl

2.14g of sodium sulfide will react with 1.99 g of HCl

2.14 Na2S + 1.99 HCl ----> (2* 58.44/78.0452) *2.14 NaCl + (34.1/78.0452) * 2.14 H2S

2.14 Na2S + 1.99 HCl ----> 3.20 NaCl + 0.935 H2S

How many grams would be in 1.752 x10^26 formula units of Ca(No3)2

Answers

Answer:

47730 grams.

Explanation:

First we convert 1.752x10²⁶ formula units of Ca(NO₃)₂ into moles, using Avogadro's number:

1.752x10²⁶ formula units ÷ 6.023x10²³ formula units/mol = 290.88 mol

Then we convert 290.88 moles of Ca(NO₃)₂ into grams, using the molar mass of Ca(NO₃)₂:

290.88 mol * 164.088 g/mol = 47730 g

If 10.5 g of iron, at 25°C, absorbs 128 J of heat, what will be the final temperature of metal? (The specific heat of iron is 0.449 J g-1 °C-1)

Answers

Answer:

27.5°C = Final Temperature of the metal

Explanation:

The change in temperature using the specific heat of a material could be obtained using the formula:

Q = m*S*ΔT

Where Q is heat absorbed in Joules = 128J in the problem

m is the mass of the substance = 10.5g

S is Specific Heat of the substance = 0.449J/g°C for Iron

ΔT is change in temperature = Final T - Initial T

Replacing:

128J = 10.5g*0.449J/g°C*ΔT

2.5°C = ΔT

2.5°C = Final T - 25°C

27.5°C = Final Temperature of the metal

How much energy is required to raise the temperature of a 300.0

gram block of lead from 22.3°C to 59.9°C? The specific heat of lead is

0.129 J/gºC.

Answers

Answer:

Q = 1455.12 Joules.

Explanation:

Given the following data;

Mass = 300 grams

Initial temperature = 22.3

Final temperature = 59.9°C

Specific heat capacity = 0.129 J/gºC.

To find the quantity of energy;

[tex] Q = mcdt[/tex]

Where,

Q represents the heat capacity.

m represents the mass of an object.

c represents the specific heat capacity of water.

dt represents the change in temperature.

dt represents the change in temperature.

dt = T2 - T1

dt = 59.9 - 22.3

dt = 37.6°C

Substituting the values into the equation, we have;

[tex] Q = 300*0.129*37.6 [/tex]

Q = 1455.12 Joules.

A compound contains 1.2 g of carbon, 3.2 g of oxygen and 0.2g of hydrogen. Find the formula of the compound

Answers

Answer:

The empirical formula of the compound is [tex]C_{0.504}HO_{1.008}[/tex].

Explanation:

We need to determine the empirical formula in its simplest form, where hydrogen ([tex]H[/tex]) is scaled up to a mole, since it has the molar mass, and both carbon ([tex]C[/tex]) and oxygen ([tex]O[/tex]) are also scaled up in the same magnitude. The empirical formula is of the form:

[tex]C_{x}HO_{y}[/tex]

Where [tex]x[/tex], [tex]y[/tex] are the number of moles of the carbon and oxygen, respectively.

The scale factor ([tex]r[/tex]), no unit, is calculated by the following formula:

[tex]r = \frac{M_{H}}{m_{H}}[/tex] (1)

Where:

[tex]m_{H}[/tex] - Mass of hydrogen, in grams.

[tex]M_{H}[/tex] - Molar mass of hydrogen, in grams per mole.

If we know that  [tex]M_{H} = 1.008\,\frac{g}{mol}[/tex] and [tex]m_{H} = 0.2\,g[/tex], then the scale factor is:

[tex]r = \frac{1.008}{0.2}[/tex]

[tex]r = 5.04[/tex]

The molar masses of carbon ([tex]M_{C}[/tex]) and oxygen ([tex]M_{O}[/tex]) are [tex]12.011\,\frac{g}{mol}[/tex] and [tex]15.999\,\frac{g}{mol}[/tex], then, the respective numbers of moles are: ([tex]r = 5.04[/tex], [tex]m_{C} = 1.2\,g[/tex], [tex]m_{O} = 3.2\,g[/tex])

Carbon

[tex]n_{C} = \frac{r\cdot m_{C}}{M_{C}}[/tex] (2)

[tex]n_{C} = \frac{(5.04)\cdot (1.2\,g)}{12.011\,\frac{g}{mol} }[/tex]

[tex]n_{C} = 0.504\,moles[/tex]

Oxygen

[tex]n_{O} = \frac{r\cdot m_{O}}{M_{O}}[/tex] (3)

[tex]n_{O} = \frac{(5.04)\cdot (3.2\,g)}{15.999\,\frac{g}{mol} }[/tex]

[tex]n_{O} = 1.008\,moles[/tex]

Hence, the empirical formula of the compound is [tex]C_{0.504}HO_{1.008}[/tex].

Given 1.24 liters of a 2.00 M solution of iron(II) chloride and unlimited sodium carbonate, how many grams of iron(II) carbonate can the reaction produce? The reaction can produce grams of iron(II) carbonate.

Answers

Answer:

Explanation:

To solve this problem we have to find the moles of iron(II) chloride that react. Using the chemical equation, we can kknow moles FeCl2 = Moles FeCO3. Thus, we can find the moles of FeCO3. Converting these moles to grams using its molar mass -Molar mass FeCO3: 115.854g/mol-

Moles FeCl2 = Moles FeCO3:

1.24L * (2.00mol / L) = 2.48 moles FeCl2

Mass FeCO3:

2.48mol * (115.854g / mol) =

What is the density of an object that has a mass of 350 g and a volume of 95 cm?? Would
this object float in water?

Answers

Answer:

Density= 3.68g/cm³

The object will sink in water

Explanation:

D=m/v

=350/95

=3.684

≈3.68g/cm³

Water= 1g/cm³

The object will sink in water because the object is denser than the water.

3.684g/cm³ is the density of an object that has a mass of 350 g and a volume of 95 cm³. The object will sink in water.

What is density?

The density of a material (volumetric density and specific mass) is its mass per unit volume. The most common sign for density is however the Roman letter D can be used as well. Density is defined mathematically as mass divided with volume.

The density of a pure material has the same numeric values just like its mass concentration. Various materials have varied densities, and density can be important in terms of buoyancy, purity, and packing.

D=m/v

=350/95

=3.684g/cm³

The object will sink in water

Therefore, 3.684g/cm³ is the density of an object that has a mass of 350 g and a volume of 95 cm³. The object will sink in water.
