what happens inside a can of solid food as gas is produced

This problem is providing an equilirium reaction with the initial concentration of COCl2 and the equilibrium concentration of Cl2 for us to calculate the equilibrium constant. At the end, the result is 0.00166.

In chemistry, not all chemical reactions turn out into completion yet reach a point of constant concentrations (conversion) called equilibrium. In such a way, since this problem is based on this phenomenom, we can start by setting up the equilibrium expression:

[tex]Kc=\frac{[CO][Cl_2]}{[COCl_2]}[/tex]

Where each concentration is at equilibrium. Now, since all these species are in 1:1 mole ratio, we can see that the cocentration that changed up to equilibrium is 3.38×10⁻² M (Cl2's concentration), and thus we can calculate Kc with:

[tex]Kc=\frac{(3.38x10^{-2}M)(3.38x10^{-2}M)}{(0.723M-3.38x10^{-2}M)}\\\\Kc=0.00166[/tex]

Answer:

357.14 cm^3

Explanation:

From Law of Proportions,

P1V1/T1 = P2V2/T2

750 x 200 / 15 = 700 x V2 / 50

50 x 200 = 14 x V2

V2 = 10000 / 14

     = 5000 / 14

     = 357.14

Avogadro's number is the number of particles in one mole of a pure substance.

The Avogadro number or constant was ned after an Italian scientist that discovered it and He is called Amedeo Avogadro. It is the the number of particles in one mole of a substance or it can be refer to the proportionality factor that of a number of constituent particles in a sample with the amount of substance contained in the sample. Its SI unit = 6.02214076×10²³ mol⁻¹.

Therefore, Avogadro's number is the number of particles in one mole of a pure substance.

We can better define the problem by saying that solution is concentrated or diluted with respect to solution B or D respectively.

The concentration of solution C lies somewhere between that of B and D.

Thus, if we are to qualify the concentration of solution C with respect to that of B, we will say it is concentrated.

If we are to qualify the concentration of solution C with respect to that of D, we will say solution C is diluted.

Answer:

0.66 L

Explanation:

Here it's given that a sample of Neon occupies a volume of 0.220 L at 0.86 atm . And we need to find out its volume at 29.4 kPa .

If we assume temperature to be constant , then we can apply Boyle's Law , which states that ,

" For a fixed amount of gas at constant temperature , pressure is inversely proportional to the volume . "

Mathematically ,

[tex] P \propto \dfrac{1}{V}[/tex]

Taking k as constant ,

[tex] P =\dfrac{k}{V}[/tex]

And we can say that ,

[tex] P_1 V_1 = P_2V_2[/tex]

Here ,

As we know that ,

[tex] 0.987 atm = 10^5\ Pa [/tex]

So ,

[tex] 29400 Pa = 0.29 \ atm [/tex]

So that ,

[tex] (0.87 atm )(0.220L) = (0.29atm)(V_2)\\[/tex]

[tex] V_2 = \dfrac{0.87 \times 0.220}{0.29} L [/tex]

Simplify ,

[tex] V_2 = 0.66\ L [/tex]

Hence the new Volume of the gas is 0.66 L .

Answer: 0.18

Explanation:

the molarity equation is moles of solute over L of solution:

mol (solute)/L (solution

so you need to convert 6.14g of LiNO3 into moles so:

6.14g LiNO3 • 1 mol

———— = 0.0890552 mol

68.946g LiNO3 (molar mass)

then you need to convert 505ml to L:

505/1000= 0.505

then you just follow the equation

0.0890552 mol / 0.505 L = 0.17634694 or 0.18 for sigfigs

0.18 M

Answer and Explanation:

Oceans are like giant swimming pools for marine life. Not really for people though. One difference that most swimming pools tend to have chlorine in them. If not, then they have salt water similar to an ocean. The chemical substance chlorine is not good for marine life at all, and isn't really good for people either.

But instead of chlorine, oceans have types of bacteria that aren't good for people either, especially if ingested in high amounts. So, if you've ever accidentally swallowed sea water and felt a little sick to your stomach, this could be why. They are similar though because they both have water and a form of bacteria.

They are not connected in a way of cycling water with each-other, but they do have similarities and differences as I had mentioned before.

Interesting question - especially if you are afflicted by something like Leukemia where it pays to know everything you can about Hemoglobin.

Molecules

1 mole of anything has 6.02 * 10^23 in this case molecules

6.4*10^-3 moles has x number of molecules

Set up the proportion

1/6.4*10^-3   =  6.02 * 10^23 molecule / x          Cross Multiply

x = 6.4*10^-3 * 6.02 * 10^23

x = 3.853*10^21 molecules

Mass Hemoglobin

1 mol of hemoglobin is 64456 grams

6.4*10^-3 moles = x grams                                  Cross multiply

x = 64456 * 6.4*10^-3

x = 412.5 grams of hemoglobin in this woman's body.

If you are American and think in pounds, then this is roughly a pound of hemoglobin.

Considering that you need hemoglobin to carry oxygen around to various organs, it is not an awful lot. That's the miracle of the human body.

The name of an aqueous solution of  [tex]H_{2}S[/tex] is "hydrogen sulfide solution" or "sulfhydric acid solution."

It is a chemical formula which represents the compound hydrogen sulfide, which consists of two hydrogen atoms bonded to a sulfur atom. When [tex]H_{2} S[/tex] dissolves in water ([tex]H_{2}O[/tex]), forms an aqueous solution.

The naming for acid solutions is based on the corresponding acid's name. Here, H2S is an acid called sulfurous acid. The -ous suffix is used to refer to an acid derived from a non-oxygen-containing anion, here, the sulfide anion (S2-). When  acid is dissolved in water, the resulting solution is called as "sulfurous acid solution."

Therefore, the name for an aqueous solution of H2S is "sulfurous acid solution."

This problem is providing the number of molecules of nitrogen at STP and asks for the volume they take up. At the end, the result turns out to be 33.6 L according to the following.

In chemistry, gas laws are used to relate pressure, temperature, volume and moles as an indicator of the behavior of gases. Thus, since this problem provides the number of molecules of nitrogen gas at STP, standard pressure and temperature (1atm and 273K), one knows the Avogadro's law must be utilized.

In such a way, this law allows us to know that 1 mole of any substance is related to 6.022x10²³ particles and that 1 mole of the gas occupies 22.4 L at STP. Hence, we can find the volume with the following setup:

[tex]9x10^{23}molecules*\frac{1mol}{6.022x10^{23}molecules} *\frac{22.4L}{1mol} \\\\=33.5L[/tex]

Which can be rounded then to 33.6 L.

Answer:

21.7 kj

Explanation:

The heat required to change the phase of a matter is calculated by using the latent heat formula, Q=ML, where M is the mass released or absorbed during the phase change and L is the latent heat of a material. Since ice is melted into water, this process is technically called the heat of endorthermic phase change that is Q_in=ml

The latent heat of water is 334 kg/kj. In order to melt 65. 0g of ice Q=0.065 x 334kj/kg =21.71 of heat required
