The equilibrium concentrations of A, B, and C at equilibrium are:

The equilibrium concentrations of A, B, and C are calculated from the equilibrium equation below as follows:

Kc = [C]⁴ /  [A]³ * [B]²  -----(1)

Kc = 1.33 * 10

The initial concentrations of A and B are as follows:

A = 1.80 mol / 1 L = 1.8 M

B = 3.50 mol / 1 L = 3.50 M

The concentrations at equilibrium are given by the ICE table below:

   3 A (g)   +    2 B (g) ⇄ 4 C (g)

I   1.80            3.50           0

C  - 3x           - 2x           + 4x

E  1.80 - 3x   3.50 - 2x    4x

Substituting the concentrations at equilibrium into the equilibrium equation above

1.33 * 10³¹  = 4x⁴ / (1.80 - 3x)³ * (3.50 - 2x)²

x = 0.56

Therefore;

the concentration of A = 1.80 - 3 * 0.56

the concentration of A = 0.12 M

the concentration of B = 3.50 - 2 * 0.56

the concentration of B = 2.38 M

the concentration of C = 4 × 0.56

the concentration of C = 2.24 M

From the reactivity order, we can see that Tin is more reactive than lead. Hence Tin can replace lead from its salt through the strip of solid lead metal.

A chart listing metals in decreasing order of reactivity is called the metals reactivity series.

A metal generally reacts with other chemicals more forcefully the more reactive it is. The easier it is for positive ions to form when losing electrons (cations).

An empirical, calculated, and structurally analytical progression of a group of metals, grouped in order of their "reactivity" from highest to lowest, is known as a "reactivity series" in chemistry.

The equations can be stated as

Pb(s) + Sn[tex](NO_{3})_2[/tex] (aq) → no reaction

Sn (s) + Pb [tex](NO_{3})_2[/tex] → reaction occurs

The concentration of the methylamine chloride is 0.0000013 M.

We know that the concentration has to do with the amount of the substance that is present. Hence, the question is essentially trying to ask us to be able to find the  the concentration of methylamine chloride in the solution.

[H^+] = Antilog(-0.20) = 0.63 M

Ka = 1 * 10^-14/4.6*10^-4 = 2.22 * 10^-11

Let us first set up the ICE table as shown below;

            CH3NH2(aq)    +  H^+  ⇄  CH3NH3^+(aq)   + OH^-(aq)

I               0.15                   0.63         0                         0

E         0.15 - x                0.63 -x        x                          x

Ka = [CH3NH3^+] [OH^-]/[CH3NH2] [H^+]

2.22 * 10^-11= x^2/[0.15 - x] [0.63 -x ]

2.22 * 10^-11(0.09 -0.15x - 0.63x + x^2) = x^2

2.22 * 10^-11(0.09 - 0.48x +x^2) = x^2

1.9 * 10^-12 - 1.1 * 10^-11x + 2.22 * 10^-11x^2 = x^2

x^2 - 2.22 * 10^-11x^2 +  1.1 * 10^-11x  - 1.9 * 10^-12  = 0

x^2 +  1.1 * 10^-11x  - 1.9 * 10^-12  = 0

The enthalpy of the reaction is obtained as 242 kJ/mol

We define the term enthalpy as the heat that is evolved or absorbed in a chemical process. In this case, heat is evolved when the reaction occurs because a neutralization reaction is necessarily an exothermic reaction. This is because het is given off.

We have been supplied with the amount of that is produced in the process. Hence we have;

Number of moles of sodium metal = 0.442g /23 g/mol = 0.019 moles

Answer:

Explanation:

By creating complex ions, altering the solution's pH, or raising the temperature to redissolve part of the solids, metal ions that precipitate together can be separated using a variety of different methods.

The empirical formula of the caffeic acid is C₂H₂O.

The mass composition of the carbon and hydrogen in the carbon dioxide and water respectively is calculated as follows;

mass of carbon in 220 mg of CO₂ = (12 x 0.22 g)/(44) = 0.06 g

mass of hydrogen in 40.3 mg of H₂O = (2 x 0.0403 g) / (18) = 0.0045 g

mass of oxygen = 0.1 g - (0.06 g + 0.0045 g) = 0.0355 g

The molar composition of the elements is calculated as follows;

H = 0.0045 /1 = 0.0045

C = 0.06 / 12 = 0.005

O = 0.0355 / 16 = 0.0022

Divide through with the smallest molar composition

H = 0.0045 / 0.0022 = 2

C = 0.005/0.0022 = 2

O = 0.0022/0.0022 = 1

The relationship among force, mass, and acceleration is force equals mass times acceleration. Therefore, option B is correct.

The term acceleration is defined as the rate of change of velocity. When an object moves in a circular path at a constant speed, it is still accelerating because its velocity direction changes.

The application of a net force to an object alters its motion, the greater the net force, the greater the acceleration. More massive objects necessitate greater net forces to accelerate at the same rate as less massive objects.

“Force equals mass times acceleration.” This is because this shows the equation for force, and thus it shows the relationship between them in how they are used.

The balanced chemical equation for rusting iron is:

4Fe + 3O2 = 2Fe2O3

If we divide 1.0x10^9 by Avogadro's number, we get the amount of moles of oxygen which is 1.6611x10^-15 moles.

From the chemical equation we know that it takes 3 moles of oxygen to produce 2 moles of iron oxide. So if we multiply the moles of oxygen calculated by 2/3, we can get the moles of iron oxide.

(1.611x10^-15)(2/3)  = 1.107419x10^-15 moles of iron oxide.

If we multiply the moles of iron oxide by the molar mass of iron oxide, we get how many grams of iron oxide would be produced by 1 billion oxygen atoms. Which is the same thing as how many grams of iron oxide contain 1 billion oxygen atoms.  

(1.107419x10^-15)(159.69) = 1.8x10^-13 grams of Fe2O3

When this process happens, these gases react with each other to produce pure oxygen gas. The reaction between the gases also produces heat, which causes more alumina to break down from its original form.
