Explanation:

Answer:

As you go up the fractionating column, the hydrocarbons have: lower boiling points lower viscosity (they flow more easily) higher flammability (they ignite more easily) This means that in general hydrocarbons with small molecules make better fuels than hydrocarbons with large molecules.

The total amount of heat energy absorbed by the water is 104.6 Joules.

To calculate the total amount of heat energy absorbed by the water, we need to use the specific heat capacity of water, which is 4.184 Joules per gram degree Celsius (J/g°C).

The change in temperature of the water is ΔT = 15°C - 10°C = 5°C.

The amount of heat energy absorbed by the water can be calculated using the formula:

Q = m x c x ΔT

where Q is the amount of heat energy absorbed, m is the mass of the water, c is the specific heat capacity of water, and ΔT is the change in temperature.

Substituting the given values, we get:

Q = 5 g x 4.184 J/g°C x 5°C

Q = 104.6 Joules

Heat and temperature are related concepts but they are not the same thing. Temperature is a measure of the average kinetic energy of the particles in a substance, while heat is the energy that is transferred between two objects as a result of a temperature difference. Temperature is measured using a thermometer and is expressed in units such as degrees Celsius or Fahrenheit. The temperature of a substance is directly proportional to the average kinetic energy of its particles - the higher the temperature, the faster the particles are moving.

What is the percent yield of lithium hydroxide from a reaction of 7.40 g of lithium with 10.2 g of water? The actual yield was measured to be 12.1 g.

The concentration of the original Ba(OH)₂ solution if 15.0 ml solution of Ba(OH)₂ is neutralized with 22.7 ml of 0.200 m HCl is 151.3 mol/dm³

To determine concentration of the original Ba(OH)₂ solution, we must know he balanced chemical equation for the neutralization reaction is:

Ba(OH)₂ + 2HCl → BaCl₂ + 2H₂O

From the equation above, the stoichiometric ratio of Ba(OH)₂ and HCl is 1:2. That means one mole of Ba(OH)₂ reacts with 2 moles of HCl. The balanced chemical equation also shows that the number of moles of HCl used is the same as the number of moles of Ba(OH)₂. Hence:

moles of HCl = 0.200 mol/dm³ × 22.7 dm³ = 4.54 mol

Using the stoichiometric ratio, the moles of Ba(OH)₂ in the solution can be calculated to be:

moles of Ba(OH)₂ = 4.54 mol ÷ 2 = 2.27 mol

The volume of the Ba(OH)₂ solution is 15.0 mL, which is 0.015 dm³. Therefore, the concentration of the original Ba(OH)₂ solution can be calculated as:

concentration = moles/volume= 2.27 mol ÷ 0.015 dm³= 151.3 mol/dm³

The concentration of the original Ba(OH)₂ solution is 0.302 M.

Given data

Volume of Ba(OH)₂ solution used = 15.0 ml

Volume of HCl used = 22.7 ml

Molarity of HCl solution used = 0.200 M

We need to calculate the concentration of Ba(OH)₂ solution, which is not known.Molar ratio of HCl and Ba(OH)₂ in a balanced chemical equation of their neutralization is;

HCl + Ba(OH)₂ → BaCl₂ + 2H₂O

The balanced chemical equation tells us that 1 mole of HCl is required to neutralize 1 mole of Ba(OH)₂.

So, the moles of HCl used in the reaction is;

moles of HCl = molarity × volume (in liters)

moles of HCl = 0.200 M × 0.0227 L = 0.00454 mole

Since one mole of HCl reacts with 1 mole of Ba(OH)₂,

so the number of moles of Ba(OH)₂ used is also equal to 0.00454 mole. Since we know the volume of the Ba(OH)₂ solution used, we can calculate the molarity of the solution as;

molarity = moles of solute / volume of solution in liters

Molarity = 0.00454 / (15.0 / 1000) = 0.302 M

Therefore, the concentration of the original Ba(OH)₂ solution is 0.302 M.

Answer:

480.06 g/mol, Thorium nitrate.

Explanation:

The molar mass of the unknown gas is 555.6 g/mol that can be calculated using Grahams' las of effusion.

The molar mass of gas 1= M1

The molar mass of gas 2= M2

As per Graham's law of effusion,

Rate1/Rate2= (M2/M1)1/2

Here, rate 1 is the rate of effusion of the first for the first gas and rate 2 is the rate of effusion for the second gas.

Substituting the given values,

Rate 1= 1.0 L/30 s

Rate 2= 1.0 L/125 s

Then,

[1/30]/[1/125]=(M2/32.0 g/mol)1/2

M2=555.6 g/mol

Therefore, the molar mass of the unknown gas is 555.6 g/mol.

Answer:

O spongy layer is the right answer

Russian chemist Dmitri Mendeleev

The final temperature of the gas is approximately 40.96 Kelvin.

To determine the final temperature of the gas, we can use the ideal gas law, which states:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles of the gas, R is the ideal gas constant, and T is the temperature in Kelvin.

First, let's convert the given temperatures to Kelvin. We have:

Initial temperature: -125 degrees Celsius = 148 K (approximate)

Final temperature: Unknown

The initial conditions of the gas are as follows:

Initial pressure (P1) = 1.25 atm

Initial volume (V1) = 1250 mL = 1.25 L (since 1 L = 1000 mL)

Initial temperature (T1) = 148 K

The final conditions of the gas are as follows:

Final pressure (P2) = 50.0 atm

Final volume (V2) = 325 mL = 0.325 L

Final temperature (T2) = Unknown

Using the ideal gas law, we can set up the following equation:

(P1 * V1) / T1 = (P2 * V2) / T2

Substituting the known values:

(1.25 atm * 1.25 L) / 148 K = (50.0 atm * 0.325 L) / T2

Simplifying the equation:

T2 = (50.0 atm * 0.325 L * 148 K) / (1.25 atm * 1.25 L)

T2 = 40.96 K

Vapor density is defined as the amount of weight of a gas or vapor in comparison to air.

The relative weight of a gas or vapor in comparison to air, which has an arbitrary value of one, is defined as vapor density. If a gas's vapor density is less than one, it will rise in air. When the vapor density exceeds one, the gas will normally sink in air.

Vapor density is only a broad concept used to estimate where vapors might be discovered when released. This physical parameter, however, is not absolute and can be influenced by:

Explanation:

The IUPAC name of the compound NaB(OH)4 is sodium tetrahydroxyborate.

The compound NaB(OH)4 is made up of sodium ions (Na+) and tetrahydroxyborate anions (B(OH)4-).

According to IUPAC naming conventions, the name of an ionic compound is written by listing the cation first, followed by the anion. In this case, the cation is sodium (Na+) and the anion is tetrahydroxyborate (B(OH)4-).

To name the tetrahydroxyborate anion, we start by identifying the boron atom, which has a valency of three. The hydroxide ions (OH-) are then added to balance the charge, resulting in the formula B(OH)4-.

The prefix "tetra-" indicates that there are four hydroxide groups attached to the boron atom. The suffix "-ate" is used to indicate that this is an anion.

Finally, the name of the compound is written as "sodium tetrahydroxyborate" because it contains one sodium cation and one tetrahydroxyborate anion.

D is the correct answer. One of the peaks overlaps with the sp C-H peaks.

Fermi doublets are small peaks in nuclear magnetic resonance (NMR) spectra caused by nuclei of two adjacent atoms in a coupling. They are frequently difficult to identify due to their small size in comparison to other peaks in the NMR spectrum. Furthermore, one peak in the doublet can overlap with other peaks in the spectrum, particularly sp3 C-H peaks, making the Fermi doublet difficult to distinguish from other peaks. This can lead to the Fermi doublet being missed or misinterpreted in NMR analysis, resulting in errors in peak assignment and molecular structure identification.

Answer:it’s b they transfer thermal energy away from earths core towards its crust

Explanation:

Good luck!

Thermal energy moves from the outer core, through the mantle, and to the  crust by conduction.

Heat transferred from the core through the mantle and to the crust in the process of conduction. The lower mantle is heated directly by conduction from the core. In conduction, heat is transferred from one particles to another.

In the process of conduction, heat flows from warmer objects to cooler objects so the outer core has high amount of heat energy which is transferred to the surrounding mantle layer due to its lower temperature so we can conclude that thermal energy moves from the outer core, through the mantle and to the crust by conduction.
