Answer 1

If the volume is decreased to 2.6 L and pressure is decreased to 3.2 atm, then temperature become 156.98K.

This problem can be solved by using the concept of Ideal gas equation.

What ia ideal gas equation?

The equation of ideal gas can be expressed as

PV = nRT

where,

P is the pressure of the gas

V is the volume taken

n is the number of moles of the gas

R is the gas constant = 6.314 J/ mol K

T is the temperature

Now from given data, we have the values of

V = 3.2 L

P = 5.5 atm

T = 53°C = 273 + 53 = 326 K

By substituting all the values, we get the value of n

3.2 × 5.5 = n × 6.314 × 326

17.6 = n × 2058.36

n = 17.6 / 2058.36

n = 0.0085 mol

Now, we have to find the temperature

n = 0.0085 mol

V = 2.6 L

P = 3.2 atm

By substituting all the values, we get

3.2 × 2.6 = 0.0085 × 6.314 × T

8.32 = 0.053 T

T = 8.32/ 0.053

T = 156.98 K

Thus, we concluded that if the volume is decreased to 2.6 L and pressure is decreased to 3.2 atm, then temperature become 156.98K.

Answers

An orbital energy level diagram for the ground state of a nitrogen atom is option A is correct.

What is energy level diagram?

Energy level diagram is defined as a visual representation of the energies of an atom's or molecule's various orbitals. The energy shifts when it switches between energy levels or when it jumps to a different shell. As a result, a shell also indicates an electron's energy along with its location, and these are known as energy levels.

Seven electrons make up the atom of nitrogen. Let's write the orbital notation of the atom in order to build the orbital energy level diagram: 7 electrons of nitrogen:

What effects does a dysfunctional nervous system have on other systems of the body? Provide at least one specific example.

Considering the nervous system is the "control center" of the human body, without a functioning nervous system, there would be no way for signals to reach other organ systems in the body. An example of this can be seen with the muscular and skeletal systems. If the brain is unable to send out signals to these two organ systems, then they would cease to move or even stand up straight. Say if you were to break your spinal cord, there would be no way for the brain reach your leg muscles because the nerves in your spine are now damaged and can therefore not carry out signals from the brain.

The milliliters of 232 quantity of HCl required for preparing 1M HCl.

The fact that water has a concentration of 10-7 for both hydronium and hydroxide must be taken into account when the concentration of acids  very close to or less than 10⁻⁷.

We frequently overlook the ion concentration in water for the same reason that we frequently ignore the mass of electrons (we just add the protons and neutrons), which is that they are so minute. For taking the -log conc, there is an exception in this case.

M1 * V1 = M2 * V2

10.5 * V1 = 1 * 740

V1 = 70.48 ml

Initial moles of solute are calculated as follows: molarity * volume in liters = 12 * (61/1000) = 0.0732 moles.

The 238 ml of solution now contains these moles.

0.0732 moles are present in 238 ml of solution.

Therefore, 119 ml of solution will contain = 0.0732 * 119 / 238 = 0.0366 moles of solute.

As of right now, the solution's total volume is 119 /113 = 232 ml, or 0.232 liters.

Final concentration is equal to moles divided by the volume in liters, or 0.0366/0.232, or 0.158 M.

Answers

Water has a 4.18 J/g specific heat capacity at 0 °C. Since 1500 ml of water weighs 1500 g, the enthalpy change for a 24.2 to 25.9 degree Celsius temperature difference is 10659 per mole or 1065.9 for 0.1 mol.

Describe calorimetry.

Calculating a reaction's enthalpy change analytically is called calorimetry. Given by, is the calorimetric equation that links mass, temperature difference, and specific heat capacity (c).

q = mc ΔT

given that the water has a 1500 ml capacity. Since water has a density of 1 g/ml, its mass is 1500 g. Water has a specific heat capacity of 4.18 J/°C g. Therefore, the following formula is used to compute the thermal energy of the reaction:

q = 1500 g ×  4.18 J/ °C g × (25.9 - 24.2 °C)

What are organic molecules?

In chemistry, organic compounds are generally any chemical compounds that contain carbon-hydrogen or carbon-carbon bonds. Due to carbon's ability to catenate (form chains with other carbon atoms), millions of organic compounds are known. The study of the properties, reactions, and syntheses of organic compounds comprise the discipline known as organic chemistry. For historical reasons, a few classes of carbon-containing compounds (e.g., carbonate salts and cyanide salts), along with a few other exceptions (e.g., carbon dioxide, hydrogen cyanide), are not classified as organic compounds and are considered inorganic. Other than those just named, little consensus exists among chemists on precisely which carbon-containing compounds are excluded, making any rigorous definition of an organic compound elusive.

Although organic compounds make up only a small percentage of Earth's crust, they are of central importance because all known life is based on organic compounds. Living things incorporate inorganic carbon compounds into organic compounds through a network of processes (the carbon cycle) that begins with the conversion of carbon dioxide and a hydrogen source like water into simple sugars and other organic molecules by autotrophic organisms using light (photosynthesis) or other sources of energy. Most synthetically-produced organic compounds are ultimately derived from petrochemicals consisting mainly of hydrocarbons, which are themselves formed from the high pressure and temperature degradation of organic matter underground over geological timescales.  This ultimate derivation notwithstanding, organic compounds are no longer defined as compounds originating in living things, as they were historically.
