This problem is providing us with the reaction whereby methane is produced from solid carbon and gaseous hydrogen, as well as its Kp and asks for the total pressure at equilibrium for a specified addition of reactants. At the end, the answer turns out to be 11.7 atm.
Chemical equilibriumIn chemistry, when a chemical reaction takes place, it proceeds until a point called equilibrium, where the concentration of all the species start becoming unchanged. Thus, we can use equilibrium expressions whenever we needed pressures or concentrations at equilibrium.
In this case, for the reaction we were given, we can write the following equilibrium expression, where the solid carbon is excluded:
[tex]Kp=\frac{p_{CH_4}}{p_{H_2}^2} =0.263[/tex]
Which can also be written in terms of the reaction extent and the initial pressure of hydrogen:
[tex]0.263=\frac{x}{(p_{H_2}^0-2x)^2}[/tex]
Thus, we calculate the initial pressure of hydrogen with the temperature and volume of the flask:
[tex]p_{H_2}^0=\frac{(4.50g/2.02g/mol)*0.08206\frac{atm*L}{mol*K}*1000K}{10.0L}\\ \\p_{H_2}^0=18.3atm[/tex]
Hence, we solve for x in the equilibrium expression as follows:
[tex]0.263=\frac{x}{(18.3-2x)^2}\\\\x_1=6.64atm\\\\x_2=12.6atm[/tex]
Where the correct value is 6.64 atm because the 12.6 atm turns out into a negative pressure for hydrogen at equilibrium. Finally, we calculate the total pressure with:
[tex]P_T=p_{CH_4}+p_{H_2}=x+18.3-2x\\\\P_T=6.64atm+18.3atm-2*6.64atm\\\\P_T=11.7atm[/tex]

If a portion of a messenger rna molecule contains the base sequence a-a-u, the corresponding transfer rna base sequence is.
Answer:
Answer:
U-U-A
Explanation:
A mRNA molecule is formed as a result of transcription, which then proceeds to the ribosomes in the cytoplasm to undergo translation. Translation is the process whereby an amino acid sequence (protein) is synthesized using the information in the mRNA molecule/sequence. The mRNA sequence is read in a group of three nucleotide bases called CODON. Each codon specifies an amino acid.
This codon is read by another RNA molecule in the ribosome called tRNA (transfer RNA). tRNA contains another set of three nucleotides called ANTICODON, which is complementary to the CODON and responsible for reading the codon in order to carry the corresponding amino acid to the growing sequence.
According to this question, a portion of a messenger RNA molecule contains the base sequence A-A-U, the complementary anticodon sequence of the tRNA would be U-U-A.

A box is sliding down an incline tilted at an angle 14. 0° above horizontal. The box is sliding down the incline at a speed of 1. 70 m/s. The coefficient of kinetic friction between the box and the incline is 0. 380. How far does the box slide down the incline before coming to rest?.
The net forces on the box acting parallel and perpendicular to the incline, respectively, are
∑ F[para] = mg sin(14.0°) - F[friction] = ma
∑ F[perp] = F[normal] - mg cos(14.0°) = 0
where m = mass of the box and a = its acceleration.
The second equation tells us
F[normal] = mg cos(14.0°)
so that friction has a magnitude of
F[friction] = 0.380 F[normal] = 0.380 mg cos(14.0°)
Solve the first equation for a :
mg sin(14.0°) - 0.380 mg cos(14.0°) = ma
a = g sin(14.0°) - 0.380 g cos(14.0°)
a ≈ -1.24 m/s²
Assuming the box slides down the incline with constant acceleration, solve for ∆x, the distance it slides before coming to rest:
0² - (1.70 m/s)² = 2a ∆x
∆x = -(1.70 m/s)² / (2 (-1.24 m/s²))
∆x ≈ 1.16 m

At 900 ∘c,kc=0. 0108 for the reaction caco3(s)←→cao(s)+co2(g) a mixture of caco3, cao, and co2 is placed in a 10. 0-l vessel at 900 ∘c. For the following mixtures, will the amount of caco3 increase, decrease, or remain the same as the system approaches equilibrium?.
The concentration of CaCO3 increases in all cases because Q> K.
What is equilibrium?A chemical reaction is said to have attained equilibrium when the rate of forward reaction is equal to the rate of reverse reaction. We are told that the Kc of the reaction is 0. 0108.
In the first case:
CaCO3 - 15.0 g/100g/mol/10 L = 0.015 M
CaO - 15.0 g/56 g/mol/10 L = 0.027 M
CO2 - 4.25 g/44 g/mol / 10 L = 0.0096 M
Q = [0.027] [0.0096]/0.015
Q = 0.017
Since Q > K, the concentration of CaCO3 increases
In the second case;
CaCO3 - 2.5 g/100g/mol/10 L =0.0025 M
CaO - 25.0 g/56 g/mol/10 L = 0.045 M
CO2 - 5.66 g/44 g/mol / 10 L = 0.013 M
Q = [0.045 ] [ 0.013]/[0.0025 ]
Q = 0.23
Q > K the concentration of CaCO3 increases
In the third case;
CaCO3 - 30.5 g/100g/mol/10 L =0.031 M
CaO - 25.5 g/56 g/mol/10 L =0.046 M
CO2 - 6.48 g//44 g/mol / 10 L = 0.015 M
Q = [0.046] [ 0.015]/[0.031]
Q = 0.022
Q> K hence the concentration of CaCO3 increases
