methylhydrazine (ch6n2) is commonly used as a liquid rocket fuel. when 4.00 g of methylhydrazine is combusted in a bomb calorimeter, the temperature of the calorimeter increases from 25.00 oc to 39.05 oc. in a separate experiment the heat capacity of the calorimeter is measured to be 7.794 kj/oc. what is the heat of reaction for the combustion of a mole of ch6n2 in this calorimeter?

Answers

Answer 1

The heat of reaction for the combustion of a mole of C₆NH₂ in this calorimeter is  - 1.30 × 10³ kJ/mol.

The reaction is given as :

2CH6N2(l) + 5O2(g) ----> 2N2(g) + 2CO2(g) + 6H2O(l)

given that :

initial temperature = 25 °C

final temperature = 39.05 °C

heat capacity of the calorimeter = 7.794 kJ/°C

mass of methylhydrazine = 4 g

molar mass of methylhydrazine  = 46.1 g/mol

the heat of reaction Q = - C ΔT

                                       = - 7.794 × ( 39.05 - 25)

                                       = - 113.0 kJ

the heat of reaction of a mole = - (113.0 kJ / 4) × 46.1

                                                  = - 1.30 × 10³ kJ/mol

Would you expect to find calcium metal used in conducting wire or

Answers

No, we would not expect to find calcium metal used in conducting wire or structural materials. In its pure metallic form, calcium is unstable and unfit for any structural use.

Why aren't calcium-based electrical lines used?

High temperatures cause calcium to burn in the air, creating nitride and oxide. When it combines with water, hydrogen is produced. Therefore, on Earth, it cannot serve as an electrical conductor.

Is calcium an electrical conductor?

Because metals contain moving electrons, they are effective conductors of electricity. Calcium is a metal. Iodine is a non-metal, and since non-metallic elements lack mobile electrons, they are typically poor conductors or non-conductors of electricity. Consequently, solid iodine does not conduct electricity while solid calcium does. The steel cladding of the silicon-calcium alloy cored wire is covered in silicon calcium powder.

The number of bohr magnetons per atom for this material is 1.14 when some hypothetical metal that exhibits ferromagnetic behavior and that has 1 simple cubic crystal structure.

Given atomic radius of crystal structure (r) = 0.130nm

saturation flux density of crystal structure = 0.75tesla

We know that n = M/µN = B/µ0µN

n = BVc/µ0µN where Vc is the volume of crystal and B is bohr magneton

Answers

Chemical analysis shows that the oxygen-carrying protein hemoglobin is 0.34 percent Fe by mass. the actual molar mass of hemoglobin is about 65000g. There are Fe atoms in one molecule of hemoglobin

Hemoglobin efficiently transports oxygen from the lungs to the body's tissues. Additionally, it helps in the return of carbon dioxide and hydrogen ions to the lungs. For the creation of blood, iron is crucial. Red blood cells and muscle cells contain about 70% of the iron in our bodies. Given the information, we may conclude that:

Mass of Fe in hemoglobin = 0.34% of molar mass of hemoglobin

Mass of Fe in hemoglobin = 0.34% of 65000

                    = (0.34 x 65000) / 100

                    = 221 g/mol

We now understand that the molecular weight of iron (Fe) is 55.85 g/mol.

Therefore, the quantity of iron in hemoglobin divided by the molecular mass of iron gives the amount of iron in 1 mole of hemoglobin.

                                  = 221/55.85

                                  = 3.957, which is approximately equal to ‘4’

In line with this, 1 molecule of hemoglobin has 4 Fe atoms in it.

Hydrogen gas and zinc chloride are produced quickly by the reaction of zinc with hydrochloric acid. In a single displacement reaction, zinc metal displaces hydrogen to produce zinc chloride and hydrogen gas. Because the reaction is exothermic, a significant amount of heat is produced.

The reaction goes in following order

[tex]Zn(s)+2HCl(aq)\rightarrow ZnCl_{2}(aq)+H_{2} (g)[/tex]

Percentage of Zn = (mass of Zn/mass of Ore) x 100

Mass of Zn = [tex]\frac{44 \times 8.05}{100}[/tex] = 3.54g

n Zn= [tex]\frac{3.54g}{65.38g}[/tex] per mole = 0.054144

n [tex]HCl[/tex] = 2 x 0.054144 = 0.10828

Electronegativity is a measure of an atom's ability to attract electrons when it forms a chemical bond with another atom. It is based on the Pauling Scale, which assigns values to elements based on their tendency to attract electrons when they form bonds. Electronegativity increases from left to right across the periodic table, and increases from the bottom to the top of the periodic table.

how many times acidic is pOH 12 than pOH 10

Answers

Answer:

100x less acidic

Explanation:

pOH is the inverse of pH, which is a measure of the acidity or basicity of a solution. The lower the pH of a solution, the more acidic it is, and the higher the pOH, the less acidic it is.

To determine how many times more acidic a solution with a pOH of 12 is compared to a solution with a pOH of 10, we can use the formula:

pH1 / pH2 = 10^(pOH1 - pOH2)

In this case, we are given that the pOH of the first solution is 12 and the pOH of the second solution is 10. We can plug these values into the formula to calculate the ratio of acidity:

pH1 / pH2 = 10^(12 - 10)

= 10^2

= 100

Therefore, a solution with a pOH of 12 is 100 times less acidic than a solution with a pOH of 10.

The system simply balances forces against movement in order to achieve the desired output force amplification while maintaining the input power. The law of the lever can be used as an example for this.

Levers and pulleys are examples of simple machines that use mechanical advantage, a measurement of the ratio of output force to input force in a system.

A calculation known as a mechanical advantage quantifies the amplified force that a mechanical system absorbs. It provides the ratio of force applied to the load to force required to overcome that force. Since the two ratio quantities are the force, the expression has no units.
