Answers

The final solution has a pH of 1.17.

The pH of the final solution can be calculated by using the equation:

pH = -log[H+]

Where [H+] is the concentration of hydrogen ions in the solution.Hydrogen ions, also known as protons, are positively charged particles that are found in solutions.

To calculate the concentration of hydrogen ions, we need to calculate the molarity of the solution.

Molarity of HCl =[tex]\frac{ (52.3 mL * 0.1000 mol/L) }{ (1000 mL/L) }[/tex]

                          [tex]= 0.0523 mol/L[/tex]

Molarity of HNO3 = [tex]\frac{(15.8 mL * 0.1000 mol/L) }{(1000 mL/L) }[/tex]

                             [tex]= 0.0158 mol/L[/tex]

Total molarity of the solution = 0.0523 + 0.0158 = 0.0681 mol/L

[H+] = 0.0681 mol/L

pH = -log[H+]

       = -log(0.0681)

pH = 1.17

Therefore,The pH of final solution is 1.17.

In 2013, there were 2.6 x 106people living in Rome. In 2013, 2.41 x 104 people died in Rome. What was the Crude death rate?

Answers

The crude death rate in Rome in 2013 was 0.9269, or 0.9269 deaths per 1,000 people.

What is the crude death rate?

The crude death rate (CDR) is the number of deaths in a population divided by the total population, multiplied by a constant factor (usually 1,000 or 100,000) to express the rate per unit of population.

The formula for CDR is:

CDR = (Number of deaths / Total population) x Constant factor

We are given the following values:

Number of deaths (D) = 2.41 x 10^4

Total population (P) = 2.6 x 10^6

Constant factor = 1,000

Substituting these values into the formula for CDR, we get:

CDR = (D / P) x Constant factor

CDR = (2.41 x 10^4 / 2.6 x 10^6) x 1000

CDR = 9.269 x 10^-1

suggest and explain why the invention of the haber process. caused the closure of the humberstone mines in chile

Answers

In summary, the invention of the Haber process led to the production of synthetic fertilizers, which reduced the demand for natural nitrates from mines like Humberstone, ultimately leading to its closure.

The invention of the Haber process, which is a method of synthesizing ammonia from nitrogen and hydrogen gas, allowed for the production of large amounts of fertilizer. This increased the amount of farmland that could be cultivated and substantially increased crop yields. As a result, the demand for natural resources like nitrate-based fertilizers, which were previously extracted from mines like Humberstone in Chile, decreased significantly.

Humberstone was one of the largest nitrate mines in Chile and was known for producing high-quality nitrate fertilizers. However, the increased production of synthetic fertilizers through the Haber process meant that the demand for natural nitrate-based fertilizers gradually declined. The falling demand for natural nitrates eventually led to the closure of many nitrate mines like Humberstone in Chile.

In addition to the Haber process, other factors such as the discovery of cheaper sources of natural nitrates in other parts of the world and the decline in the price of nitrate also contributed to the closure of the Humberstone mines.

The value of the energy is needed to determine if energy is released or absorbed in this reaction.

Answers

Unable to tell if this process is endothermic or exothermic because it is not stated whether energy is released or absorbed.

What is energy?

Energy has the ability to perform work. It is a quantifiable quality that may be transferred to a physical system or body, and it can be seen when work is being done. Potential, kinetic, thermal, electrical, chemical, and radioactive forms of energy can all exist.

The energy shift that takes place during the reaction determines the type of reaction, whether it is exothermic or endothermic. It is an exothermic reaction if energy is released during the reaction. On the other side, a reaction is said to be endothermic if energy is absorbed during it[2]. According to the chemical equation, a + 2b + energy ab2.

You can tell whether a chemical process releases or absorbs energy overall by measuring the enthalpy of the reaction. The heat energy change that occurs as reactants turn into products is known as a reaction's enthalpy(H). H is positive if heat is absorbed throughout the process; if heat is emitted, H is negative. Exothermic processes have enthalpies that are less than zero and, as a result, are negative, while endothermic reactions have enthalpies that are more than zero and, as a result, are positive.

We cannot tell if this chemical reaction is endothermic or exothermic because the chemical equation contains no information about the value of energy.

This coordination number will be the same for every atom in the structure and will be the same irrespective of the stacking sequence (i.e., the same for HCP and FCC).

Answers

The coordination number for a single atom inside of a 3-dimensional close-packed structure is 12.

The coordination number for a single atom inside of a 3-dimensional close-packed structure is 12. This is because in a close-packed structure, each atom is surrounded by 12 other atoms, 6 in the same plane and 3 in the plane above and 3 in the plane below. This is true for both hexagonal close-packed (HCP) and face-centered cubic (FCC) structures, as the coordination number is determined by the number of atoms "touching" a given atom and is the same for every atom in the structure.

A 23.5 g sample of nacl was placed in a 500.0 ml erlenmeyer flask, which was filled to the mark with water. what is the molar concentration of the resulting nacl solution?

Answers

the molar concentration of the resulting NaCl solution is 0.804 mol/L.

The molar concentration of the NaCl solution can be calculated using the equation:

C = n/V,

where C is the molar concentration, n is the amount of substance (in moles), and V is the volume of the solution (in liters).

Given that the sample has a mass of 23.5 g and the molar mass of NaCl is 58.44 g/mol, we can calculate the amount of substance (n) in the sample:

n = 23.5 g / 58.44 g/mol = 0.402 mol

The volume of the solution (V) is equal to the volume of the Erlenmeyer flask, which is 0.500 L:

V = 0.500 L

Therefore, the molar concentration of the NaCl solution can be calculated as follows:

C = 0.402 mol / 0.500 L = 0.804 mol/L

Therefore, the molar concentration of the resulting NaCl solution is 0.804 mol/L.

the rate of a standard reaction is 0.01840 m/s at 25 oc. it is determined that this is too fast, and that the rate should be reduced to 0.0046 m/s. what temperature should the reaction be run at to achieve this?

Answers

Thus, the required temperature for the reaction to run at a rate of 0.0046 m/s is 30.7°C approximately.

The Arrhenius equation gives the relation between rate constants and activation energy, which shows how the reaction rate is affected by temperature.

It is written as: k = Ae-Ea/RT Where,

k is the rate constant

A is the pre-exponential factor (frequency factor)

Ea is the activation energy

T is the temperature in Kelvins

R is the universal gas constant

Taking natural logs of both sides of the Arrhenius equation we have: ln(k) = ln(A) - Ea/RTln(k) = -Ea/RT + ln(A)

Now we will use the following rearranged form: ln(k2/k1) = -Ea/R (1/T2 - 1/T1)

We can substitute our given values of k2 = 0.0046, k1 = 0.0184, and T1 = 25oC + 273.15K = 298.15K into the above equation to solve for T2, which is the required temperature, as follows:

ln(0.0046/0.0184) = -Ea/R (1/T2 - 1/298.15K)ln(0.25)

= -Ea/R (1/T2 - 1/298.15K)ln(4)

= Ea/R (1/T2 - 1/298.15K)0.013862

= Ea/R (1/T2 - 1/298.15K)(1/T2 - 1/298.15K)

= 0.013862 x (R/Ea)

T2 can be found by rearranging the above equation as follows:

1/T2 = 1/298.15K + 0.013862 x (R/Ea)1/T2

= 1/298.15K + 0.013862 x (8.314 J/K/mol / Ea)T2

= 1 / (1/298.15K + 0.013862 x (8.314 J/K/mol / Ea))T2

= 1 / (0.0033522 + 0.013862 / Ea)T2

= 298.15 / (0.0033522 + 0.013862 / Ea)

Substituting Ea = 50000 J/mol, we have: T2 = 298.15 / (0.0033522 + 0.013862 / 50000)T2 = 303.9 K = 30.7°C (approx)

Thus, the required temperature for the reaction to run at a rate of 0.0046 m/s is 30.7⁰C approximately.

An experiment was carried out to make lead chloride from lead nitrate. 14. 0 g of lead chloride were obtained from 16. 9 g of lead nitrate. Determine the percentage yield of lead chloride

Answers

Moles of lead nitrate used mol Product mass Molar mass Pb 207 g/mol Molar mass N 14 g/mol Molar mass o 16 g/mol =  56 .65 %

moles of Pb([tex]NO_{3}[/tex]) = 14.8 / 331 = 0.0447

∵ moles = mass / molar mass

[tex]Pb(NO_{3}) + 2Cl = pbcl_{2} + 2NO_{3}[/tex]

[tex]\frac{moles of Pb (NO_{3}) }{1} = \frac{moles of Pbcl_{2} }{1}[/tex]

moles of [tex]Pbcl_{2}[/tex] = 0.0447

Theoretical mass of [tex]Pbcl_{2}[/tex] = moles * molar mass

= 0.0447 * 278

= 12.4266

% yield = Actual mass of [tex]Pbcl_{2}[/tex] / Theoretical mass of [tex]Pbcl_{2}[/tex] * 100

= [tex]\frac{7.04}{12.4266} * 100[/tex]

= 56 .65 %

Lead(II) chloride (PbCl2) is an inorganic compound that is white strong under surrounding conditions. It is ineffectively solvent in water. Lead(II) chloride is one of the main lead-based reagents. It likewise happens normally as the mineral cotunnite.

A novel mutation is most likely the cause of the appearance of a black mouse within a population of light mice , those are inconsistent and rare events.

Why do some mice have a light color while others have a dark color?

Fur color is influenced by several genes (4:29). The majority of genes are similar, but one gene (Mc1r) separates light and dark rock pocket mice. 4:55). The color of a mouse's fur is influenced by the genotype of the MC1R gene, according to Data Set 2. Mice that have two copies of allele 2 have the fur that is the darkest.

The dark-colored mice were the result of a random mutation in the population at site A. The trait did not spread because it did not benefit the mice from selection.
