What happens to equilibrium constant when temperature?

[tex]$\mathrm{K}_{\mathrm{c}}=\frac{\left[\mathrm{H}_2 \mathrm{O}\right]_{\mathrm{eq}}}{[\mathbf{C O}]_{\mathrm{eq}}\left[\mathrm{H}_2\right]_{\mathrm{eq}}}=\frac{\mathbf{x}}{(1.5-\mathrm{x})(1.5-\mathrm{x})}=4.0$[/tex]

[tex]$x=9-12 x+4 x^2$[/tex]

x=1 or 2.25

[tex]$\left[\mathrm{H}_2 \mathrm{O}\right]_{\mathrm{eq}}=1.0 \mathrm{M}$[/tex]

The value of the equilibrium constant drops as temperature rises. In endothermic reactions, raising the temperature raises the equilibrium constant's value. When a single reaction reaches equilibrium, the concentrations of all the substances participating in that reaction are measured. This yields the numerical value of the equilibrium constant. Calculated is the ratio between the concentrations of the reactants and the products.

When you modify the system's temperature, equilibrium constants are altered. When the temperature stays the same, Kc or Kp are constant, but they change as the temperature does. The value of Kp decreases with rising temperature, as can be shown. In order to guarantee uniformity and safety, it's imperative to maintain a steady temperature in numerous procedures.

What is photon?

The discrete packet (or quantum) containing electromagnetic (as well as light) energy known as a photon is referred to as a photon. In a vacuum, which is a region that is entirely empty, photons are always moving at the same speed as light to everyone observers.

Number of photons detected = (Power output of source) x (Scan time)

Power output of new source = 0.42 x Power output of original source

Number of photons detected = (Power output of new source) x (New scan time)

Number of photons detected = (0.42 x Power output of original source) x (New scan time)

Number of photons detected = (Power output of original source) x (1.25 seconds)

dividing both side by Power output of original source to get:

(New scan time) = (Number of photons detected) / (0.42 x Power output of original source)

(New scan time) = (1.25 seconds) / (0.42)

(New scan time) = 3 seconds

Therefore, 3 seconds will be his scan time be with the new source, if his original scan time was 1.25 seconds.

Select the type of chemical bond that most commonly forms between each combination of elements as indicated.
Metallic bond → _____
Covalent bond → _____
Ionic bond → _____
Two or more metal atoms
Metal to nonmetal
Nonmetal to nonmetal

Answers

The type of chemical bond that most commonly forms between each combination of elements is Metallic bond → metallic, Covalent bond → covalent, Ionic bond → ionic.

A metallic bond is a type of chemical bond that forms between two or more metal atoms. The metallic bond is characterized by the sharing of electrons between the atoms, creating a metallic lattice structure. This type of bonding results in a strong bond that gives metals their characteristic properties such as high melting points, ductility, and conductivity.

A covalent bond is a chemical bond in which atoms share electrons. Covalent bonds typically form between nonmetal atoms and are characterized by the sharing of electrons between atoms. Covalent bonds are typically strong and result in stable compounds. They are commonly found in compounds such as water, methane and carbon dioxide.

An ionic bond is a chemical bond in which one atom loses an electron to another atom. Ionic bonds typically form between metal atoms and nonmetal atoms. Ionic bonds are characterized by the transfer of electrons, resulting in the formation of ions. Ionic bonds are typically strong and result in stable compounds, They are commonly found in compounds such as sodium chloride (NaCl) and calcium chloride (CaCl2).

Answers

If the equilibrium constant for this reaction is 23, set (3) (n-butane] 0.04 M [iso-butane] = 0.27 M, of concentrations represents an equilibrium of these two compounds.

The equilibrium constant for a reaction is the ratio of the product concentrations to the reactant concentrations at equilibrium, raised to their stoichiometric coefficients. In this case, the reaction is:

n-butane (g) <==> iso-butane (g)

The equilibrium constant for this reaction, Kc, is defined as:

Kc = [iso-butane]/[n-butane]

Therefore, if the equilibrium constant is given as 23, then at equilibrium:

[iso-butane]/[n-butane] = 23

Out of the given sets of concentrations, only set 3) represents an equilibrium of these two compounds:

[n-butane] = 0.04 M

[iso-butane] = 0.27 M

Because:

[iso-butane]/[n-butane] = 0.27/0.04 = 6.75 which is close to the equilibrium constant of 23. The other sets of concentrations represent different ratios of [iso-butane]/[n-butane] which is not equal to 23 and thus not in equilibrium.

If light travels exactly 1 meter in 1/299,772,458 of a second, how many kilometers does it travel in 4.00 years? for this question, 1 year = 365.25 days.

Answers

To solve this problem, we need to convert the time in years to seconds, and then multiply it by the speed of light to find the distance traveled.

First, we'll convert the time in years to days: 4.00 years * 365.25 days/year = 1461 days

Now we'll convert days to seconds: 1461 days * 24 hours/day * 60 minutes/hour * 60 seconds/minute = 31,557,600 sec

Now we can multiply the time in seconds by the speed of light to find the distance traveled: 31,557,600 sec * (1 meter / (1/299,772,458)) = 9.461*10^16 meters

To express the distance in kilometers we need to divide the distance in meters by 1000

9.46110^16 meters / 1000 = 9.46110^13 kilometers.

So, light travels 9.461*10^13 kilometers in 4.00 years.

1.4 x 10-2 H3O+ + 6.5 x 10-8 HSO3- → 1.4 x 10-2 OH- + 6.5 x 10-8 H3O+

The complete proton balance for the system is:

NaHSO3 + H2O <=> Na+ + H3O+ + HSO3-

HSO3- + H2O <=> H+ + SO32- + H2O

Given the reactions as:

CO(g)+3H2(g)⇄CH4(g)+H2O(g)

the rate law for the above equation is (K1) = [CH4][H2O]/[CO][H2]^3

Then [H2]^3 = [CH4][H2O]/K1[CO]

[CO2] = [CO][H2O]/K2[H2]

CH4(g)+2H2O(g)⇄CO2(g)+4H2(g)

Similarly the rate law for the above equation is (K3) = [CO2][H2]^4/[CH4][H2O]^2

Hence, mass of 6.022 × 10²³ atoms of carbon = 12g

Mass of 1 atom of carbon = 12 ÷ 6.022 ×10²³ = 1.9 × 10-²³ g/atom.

Therefore, 1.9 × 10-²³ g/atom is the mass of a single atom of carbon.

Osmosis may be defined as the movement of a solvent through a semipermeable membrane from a region of higher solute concentration to one of lower solute concentration True False

Answers

False. Osmosis may be defined as the movement of a solvent through a semipermeable membrane from a region of lower solute concentration to one of higher concentration.

Osmosis can be defined as the movement of solvent particles or water from lower solute concentration to higher solute concentration through the semipermeable membrane. This process does not require any energy. This requires only a concentration gradient. Semipermeable membranes are very thin layers of material which allows some things to pass through them. The movement of a solvent through a semipermeable membrane from a region of higher solute concentration to one of lower solute concentration is called diffusion.

The gas chromatograph, in combination with the _________________, can separate the components of a drug mixture and then unequivocally identify each substance present in the mixture.
- Mass Spectrometer

Answers

The gas chromatograph, in combination with the mass Spectrometer, can separate the components of a drug mixture and then unequivocally identify each substance present in the mixture.

A mass spectrometer can only determine a molecule's mass after it has changed into a gas-phase ion. To do this, it charges molecules electrically and converts the resulting flow of electrically charged ions into a proportionate electrical current that a data device can then read. The components of a drug mixture are separated by the gas chromatograph and mass spectrometer, which then positively identify each component. By electrically charging molecules, which results in a flow of electrically charged ions, it does this.

What is the mass, in grams, of 9.56 x 10 molecules of methanol (CH, OH) ?

Answers

The mass of given no. of molecules of methanol will be 508 grams.

First , we have to calculate the no. of moles. So, No of moles = No. of molecules / avagadros no. Therefore :

⇒9.56 x [tex]10^{23}[/tex]  / 6.02 x [tex]10^{23}[/tex]

⇒15.875 moles

Now, We know that the molecular mass of methanol is 32 grams. So, we can calculate the mass by simply multiplying the molecular mass with moles.

Therefore,

⇒15.875 x 32

508.00 grams
