How much Calcium Chloride can be produced from the reaction of 201 g of Calcium Carbonate and 201g of Hydrochloric Acid?

Mg(OH)2 is a sparingly soluble salt with a solubility product, Ksp, of 5.61×10−11. It is used to control the pH and provide nutr

Solnce55 [7]

Answer:

The ration of the molar solubility is 165068.49.

Explanation:

The solubility reaction of the magnesium hydroxide in the pure water is as follows.

$Mg(OH)_{2}\Leftrightarrow Mg^{2+}(aq)+2(OH)^{-}(aq)$

$[Mg^{2+}][OH^{-}]$

Initial 0 0

Equili +S +2S

Final S 2S

$K_{sp}=[Mg^{2+}][OH^{-}]$

$5.61\times 10^{-11}=(S)(2S)^{2}$

$S=(\frac{5.61\times 10^{-11}}{4})^{1/3}=2.41\times 10^{-4}M$

Solubility of $Mg(OH)_{2}$ in 0.180 M NaOH is a follows.

$Mg(OH)_{2}\Leftrightarrow Mg^{2+}(aq)+2(OH)^{-}(aq)$

$[Mg^{2+}][OH^{-}]$

Initial 0 0

Equili +S +2S

Final S 2S+0.180M

$K_{sp}=[Mg^{2+}][OH^{-}]$

$5.61\times 10^{-11}=(S)(2S+0.180)^{2}$

$S=1.46\times 10^{-9}M$

$Ratio\,of\,solubility=\frac{2.41\times 10^{-4}}{1.46\times 10^{-9}}=165068.49$

Therefore, The ration of the molar solubility is 165068.49.

Calculate the volume of a balloon that can hold 113.4 g of nitrogen dioxide, NO2 gas at STP-

Karolina [17]

Answer:

55.18 L

Explanation:

First we convert 113.4 g of NO₂ into moles, using its molar mass:

113.4 g ÷ 46 g/mol = 2.465 mol

Then we<u> use the PV=nRT formula</u>, where:

P = 1atm & T = 273K (This means STP)

n = 2.465 mol

R = 0.082 atm·L·mol⁻¹·K⁻¹

V = ?

Input the data:

1 atm * V = 2.465 mol * 0.082atm·L·mol⁻¹·K⁻¹ * 273 K

And <u>solve for V</u>:

V = 55.18 L

If an atom of thorium-234 were to undergo beta emission twice, which atom would result?

AnnZ [28]

Answer:

The answer to your question is U-234

Explanation:

Data

Thorium-234

beta emission twice

Definition

Beta emission is when a beta particle (electron) is emitted from an atomic nucleus.

First beta emission

²³⁴₉₀Th ⇒ ²³⁴₉₁Pa + e⁻

Second beta emission

²³⁴₉₁ Pa ⇒ ²³⁴₉₂U + e⁻

The atom will be Uranium-324

What multiplicity would you expect in a 1h nmr spectrum for the indicated proton(s)? (1 pts)

Vedmedyk [2.9K]

Triplet multiplicity would expect in a 1h NMR spectrum for the indicated proton(s).

The spectrum is the invisible radio frequencies that radio signals pass through. These signals let you make phone calls from your mobile device, tag your friends on call an Uber, and get directions to your destination, all from your mobile device.

Spectrum management is the art and science of managing the use of the radio spectrum to minimize interference and ensure that the radio spectrum is used in the most efficient manner possible for the public good. For USDOT, this focuses on supporting safe, efficient, and economical transportation. Spectrum Networks is a suite of news and sports networks owned and operated by Charter Communications, Inc.
