Answer:
[tex]P_2=16atm[/tex]
Explanation:
Hello there!
In this case, according to the given information, we can infer we need to use the Gay-Lussac's equation it order to understand this pressure-temperature relationship as shown below:
[tex]\frac{P_1}{V_1}=\frac{P_2}{V_2}[/tex]
Thus, we solve for P2 and plug in P1, T1 and T2, to obtain:
[tex]P_2=\frac{P_1T_2}{T_1}\\\\P_2=\frac{8atm*600K}{300K}\\\\P_2=16atm[/tex]

Draw the major organic product(s) of the reaction of p-bromoaniline with HNO2, HCl.
Answer:
The major product from this reaction is 4-bromobenzene diazonium chloride.
Explanation:
The reaction of p-bromoaniline with HNO2 and HCl produces diazonium salt. When primary aromatic amines are nitrosated with nitrous acid in the presence of a strong acid such as HCl, diazonium salts are frequently formed. The diazonium salts are a crucial step in the production of halides and azo compounds. The necessary reaction mechanism is depicted in the illustration in the diagram below.

A mixture of fuel and is injected into a cylinder fitted with a piston. The initial volume is 0.37 L. After the mixture is ignited, gaseous products are formed and 1885 J of energy is released by the reaction. 311 J of the released energy is lost as heat to the surroundings. To what volume would the gases expand against a constant pressure of 1.036 atm, if the remainig energy is converted to work to push the
Answer:
The gases will expand to a volume of 2.37 L
Explanation:
Gases are able to do work when they expand or compress against an external constant pressure.
This work done by gases when they expand or compress against a constant external pressure is known as pressure-volume work or PV work.
The formula for calculating the work done by gases when they compress or expand against a constant pressure is given as W = PΔV
Where ΔV is change in volume given as V2 - V1
Where V2 is final volume, V1 is initial volume
By convention, W can either be negative or positive. When work is done by the system (ΔV > 0), W is negative and when work is done on the system (ΔV < 0), W is positive.
In the gas mixture above, W = PΔV
Remaining energy, W = (1885 - 311) J = 1574 J
P = 1.036 atm = 1.036 × 760 mmHg = 787.36 mmHg
ΔV = V2 - V1
ΔV = V2 - 0.37
1574 = 1.036 (V2 - 0.37)
V2 - 0.37 = 1574/787.36
V2 - 0.37 = 1.999 L
V2 = 1.999 + 0.37
V2 = 2.369 L
Therefore, the gases will expand to a volume of 2.37 L

what is the ph of a 8.4x10^-6 M H+ solution?
Helpppooo give answer thanks
Answer:
625 mL
Explanation:
From the question given above, the following data were obtained:
Volume of stock solution (V₁) = 250 mL
Molarity of stock solution (M₁) = 5 M
Molarity of diluted solution (M₂) = 2 M
Volume of diluted solution (V₂) =?
The volume of the diluted solution can be obtained by using the dilution formula as illustrated below:
M₁V₁ = M₂V₂
5 × 250 = 2 × V₂
1250 = 2 × V₂
Divide both side by 2
V₂ = 1250 / 2
V₂ = 625 mL
Therefore, the volume of the diluted solution is 625 mL.

Answer:
The answer is C = 9.52
Explanation:
I took the test
The pOH of a solution that has a pH of 4.48 at 25°C is 9.52. Details about pH can be found below.
What is pH?pH refers to the power of hydrogen in a substance while the pOH refers to the power of hydroxyll ions. The pH of a solution ranges from 0 - 14 indicating the strength of acidity and alkalinity.
The relationship between the pH and pOH in a solution is given as follows:
pH + pOH = 14
According to this question, a solution at 25 degrees celsius has a pH of 4.48. The pOH of the solution is calculated as follows:
4.48 + pOH = 14
pOH = 14 - 4.48
pOH = 9.52

What is the reason for heat transfer from one substance to another?
Answer:
Difference in temperature
Explanation:
According to thermodynamics, heat transfer occurs when heat from a high temperature reservoir moves to a low temperature reservoir. For heat to be transferred, the two objects should have different temperatures with one having more temperature than the other. Heat transfer in solids is by conduction, in fluids is by convection and by radiation.

3. In this case, according to the given question, it turns out possible for us to say that any chemical formula, for an ionic compound, has the cation (positive) on the left and the anion (negative) on the right; thus, since Mg is a metal, which tends to lose electrons and become positively charged whereas the Cl is a nonmetal, which tends to gain electrons and become negatively charged, we have the following:
[tex]Mg^{2+}Cl^-\\\\Mg^{2+}Cl^-_2\\\\MgCl_2[/tex]
4. In this case, since lithium is a metal, as well as magnesium, it is not possible for them to switch around their charges as they will not be bonded because they will be repelled rather than attracted because of their equal positive charges.

In the coal-gasification process, carbon monoxide is converted to carbon dioxide via the following reaction: CO (g) H2O (g) CO2 (g) H2 (g) In an experiment, 0.35 mol of CO and 0.40 mol of H2O were placed in a 1.00-L reaction vessel. At equilibrium, there were 0.19 mol of CO remaining. Keq at the temperature of the experiment is __________. A) 5.47 B) 1.0 C) 1.78 D) 0.75 E) 0.56
Answer: [tex]K_{eq}[/tex] at the temperature of the experiment is 0.56.
Explanation:
Moles of [tex]CO[/tex] = 0.35 mole
Moles of [tex]H_2O[/tex] = 0.40 mole
Volume of solution = 1.00 L
Initial concentration of [tex]CO[/tex] = [tex]\frac{0.35mol}{1.00L}=0.35M[/tex]
Initial concentration of [tex]H_2O[/tex] = [tex]\frac{0.40mol}{1.00L}=0.40M[/tex]
Equilibrium concentration of [tex]CO[/tex] = [tex]\frac{0.19mol}{1.00L}=0.19M[/tex]
The given balanced equilibrium reaction is,
[tex]CO(g)+H_2O(g)\rightleftharpoons CO_2(g)+H_2(g)[/tex]
Initial conc. 0.35 M 0.40 M 0 M 0M
At eqm. conc. (0.35-x) M (0.40-x) M (x) M (x) M
Given: (0.35-x) = 0.19
x= 0.16 M
The expression for equilibrium constant for this reaction will be,
[tex]K_{eq}=\frac{[CO_2]\times [H_2]}{[CO]\times [H_2O]}[/tex]
Now put all the given values in this expression, we get :
[tex]K_{eq}=\frac{0.16\times 0.16}{(0.35-0.16)\times (0.40-0.16)}[/tex]
[tex]K_{eq}=\frac{0.16\times 0.16}{(0.19)\times (0.24)}=0.56[/tex]
Thus [tex]K_{eq}[/tex] at the temperature of the experiment is 0.56.

If the acid dissociation constant, Ka, for an acid HA is 8 x 104 at 25°C, what percent of the acid is dissociated
in a 0.50 M solution of HA at 25°C?
A
08%
Answer:
Percent dissociated = 3.92%
Explanation:
The equilibrium of the weak acid, HA, is:
HA ⇄ H⁺ + A⁻
Where Ka = 8x10⁻⁴ is: [H⁺] [A⁻] / [HA]
As both H⁺ and A⁻ comes from the same equilibrium we can write the concentrations of the species as follows:
[H⁺] = X
[A⁻] = X
[HA] = 0.50M - X
Where X is reaction coordinate
Replacing:
8x10⁻⁴ = X² / 0.50-X
4x10⁻⁴ - 8x10⁻⁴X - X² = 0
Solving for X:
X = -0.02M. False solution. There is no negative concentrations
X = 0.0196M. Right solution.
Replacing:
[A⁻] = 0.0196M
Percent of the acid that is dissociated is:
[A⁻] / [HA]₀ * 100
[HA]₀ is its initial concentration = 0.50M
0.0196M / 0.50M * 100
Percent dissociated = 3.92%to the nearest gram, what is the mass of of one spoonfull of sugar? g
