particles are always in the state of rest. true or false​

Answers

Answer 1

False

Explanation:

All the time particles are not at rest. Because in different types of matter particles act differently.

In liquid, particles are connected to each other but not they move in different directions.

In solid, particles are tightly connected to each other, there are no gap between them.

Lastly, in case of gas, particles move randomly here and there.

So, we conclude that particles are not always in state of rest.

A laboratory assistant needs to prepare 35.2 liters of hydrogen at 25.0°c and 101.3 kilopascals. this is the equation for the reaction: 2hcl ca → h2 cacl2 what volume of 2.3 m hydrochloric acid is required to produce this much gas? use the ideal gas resource.

Answers

Volume of hydrogen gas = 35.2L

Temperature of hydrogen gas = 25.0°C + 273 = 298 K

Pressure of hydrogen gas = 101.3 kPa = 1 atm

(Conversion factor 1 atm = 101.325 kPa)

Using the Ideal gas law,

PV = nRT

where P, V, n, R and T are pressure, volume, number of moles, universal gas constant and temperature respectively.

n = PV/RT

The number of moles of hydrogen gas,

n = 35.2 L x 1 atm/ 0.0821 L.atm.mol⁻¹1.K⁻¹ x 298 K

n = 1.438 moles

2HCl + Ca → H₂ + CaCl₂

Based on the given balanced equation, 1 mole of H₂ is produced from two  moles of HCl.

Since H₂ is 1.438 moles, HCl will be (1.438 x 2) moles or 2.876 moles

Given, Molarity of HCl = 2.3 M

Molarity = moles of solute / liter of the solution

Thus the volume of HCl is,

2.3 M = 2.876 moles / liter of the solution

V = 2.876 moles / 2.3 M

V = 1.25 L

Thus the volume of 2.3 M hydrochloric acid required to produce the given amount gas is 1.25 L.

In an electrolytic cell, the electrode that acts as a source of electrons to the solution is called the __________; the chemical change that occurs at this electrode is called __________.

Answers

In an electrolytic cell, the electrode that acts as a source of electrons to the solution is called the cathode; the chemical change that occurs at this electrode is called reduction.

Define Electrolyte:-

An electrolyte is a material that separates into charged ions when it is in contact with water. Cations are positively charged ions. Anions are ions that are negatively charged. A substance that may conduct an electric current when melted or dissolved in water is known as an electrolyte.

Electrochemical cell

There are three main categories of electrochemical cells. the galvanic cell, the concentration cell, and the electrolytic cell. These cells all share the same four fundamental components. These are the elements

The electrolyte serves as the conduit for current flow between the anode and the cathode. In an aqueous solution, it normally is homogeneous, but in moist soil, the concentration or kind of dissolved compounds may vary locally.The anode, which can conduct electricity and is in contact with the electrolyte, corrodes when it combines with the chemicals in the electrolyte.A metal also contacts the electrolyte at the cathode. It is protected from corrosion rather than corroded.Anode and cathode are connected by the conductor, which also completes the circuit.

A mixture of He , Ar , and Xe has a total pressure of 3.00 atm . The partial pressure of He is 0.200 atm , and the partial pressure of Ar is 0.200 atm . What is the partial pressure of Xe ? Express your answer to three significant figures and include the appropriate units.

Answers

The partial pressure of Xe is 2.60atm

The sum of the partial pressures is equal to the total pressure. Ptotal = P1 + P2 + P3... .To calculate the partial pressure of one of the components of a mixture, subtract the sum of known partial pressures of the other components from the total pressure.

Given the values of

PHe=0.20 atm

PAr=0.20 atm

Ptotal=3.00 atm

We need to find  PXe

Solution: Determine the sum of the partial pressures of helium and argon, then subtract the sum from the total pressure.

PHe+PAr =0.20 atm + 0.20=0.400 atm

PXe=3.00atm−0.400=2.60 atm

Each gas that makes up a mixture of gases has a partial pressure, which is the notional pressure of that gas as if it alone filled the original combination's complete volume at the same temperature.

According to Dalton's Law, a perfect gas mixture's total pressure equals the sum of its constituent gases' individual partial pressures.

The thermodynamic activity of a gas's molecules is gauged by its partial pressure.

Gases react, disperse, and dissolve based on their partial pressures rather than the concentrations they have in liquids or other gas combinations.

This general characteristic of gases holds true in biological chemical interactions involving gases.

Hence the partial pressure of Xe is 2.60atm

0.03154 mol H₂O is formed from 0.0636 g of hydrogen if we consider that  O₂ is a limiting reagent.

The balanced equation is

[tex]2H_{2} (g)[/tex] + [tex]O_{2} (g)[/tex] → [tex]2H_{2} O (l)[/tex]

Here, we are calculating the moles  [tex]H_{2}O (l)[/tex] from the moles of H₂ if we consider O₂ is a limiting reagent:

Given:

The mass of  H₂ = 0.0636 g

Mass of liquid present in the container:

Yes, the liquid will be present, and of 1.2481 g

Calculation:

Given:

Volume = 1.5L

Temperature = 25 + 273 = 298K

P = 23.76 torr = 0.0312 atm

Using the ideal gas equation:

PV = nRT

Where:

P: PressureV: Volumen: number of molesR: gas constant = 0.0821 L atm [tex]K^{-1}[/tex] [tex]mol^{-1}[/tex]T: Temperature

making n subject of formula:

n = [tex]\frac{PV}{RT}[/tex]

By putting all the values in the given equation, we get,

n = 0.0312 x 1.5 / 0.0821 x 298

n = 0.0019 moles

So, 0.00189 are moles of water in the vapor

Experiments were done on a certain pure substance ex to determine some of his properties there’s a description of each experiment and the table below the side whether the experiment was a physical or chemical property

Answers

Answer:

1.) Physical

2.) Physical (probably)

3.) Chemical

Explanation:

Physical changes are changes to substances in which the intramolecular structure does not change. The intermolecular bonds (bonds between molecules) may change, but the actual chemicals involved are not altered.

Chemical changes occur when intermolecular bonds are broken/formed, changing the old substance into something new. Chemical reactions are taking place and the ratio of the elements in molecules are changing.

1.) Melting is an example of a physical change. When melting occurs, the intermolecular bonds between molecules are breaking in response to the introduction of more heat. However, the substance is still the same substance (ex. ice melting is still water as H₂O has not been changed). In this example, scientists are most likely calculating velocity.

2.) Because the original substance is able to be completely removed from the water in the flask, this is probably just a physical change. I say probably because no changes are really occurring here. It is unclear but not probably that any reactions are taking place between the water and the sample as they are easily separated. This may be an example of (can't decide) depending on how must they want you to assume. The property being measured is probably density.

3.) While dissolving the sample was an example of a physical change because just the state of matter changed, when it reacts with sodium hydroxide, a chemical change occurs. Most likely, new bonds are being formed between the elements in the original sample and the elements in sodium hydroxide. This is what allows scientists to measure the pH of a solution.

What would be the vital capacity be for a man that has a tidal volume of 500mL, a residual volume of 1100 mL, an expiratory reserve of 1100 mL and an inspiratory reserve of 3000 mL

Answers

The vital capacity will be 4600ml.

What is vital capacity?

The highest amount of air a person can inhale following their maximal exhalation is known as their vital capacity. It is equivalent to the total of the inspiratory, tidal, and expiratory reserve volumes. It roughly corresponds to Forced Vital Capacity. A wet or conventional spirometer can assess a person's vital capacity.

Normal people have a 3 to 5-liter vital capacity.

It enables simultaneous inhalation of the greatest possible volume of clean air and exhalation of the greatest possible volume of stale air. So, by increasing gaseous exchange between the body's various tissues, it improves the amount of energy available for bodily function.

VC = TV₊IRV₊ERV

where,

VC = Vital capacity

TV = Tidal volume

IRV = inspiratory reserve volume

ERV = expiratory reserve volume

VC = 500 ₊ 3000 ₊ 1100

VC = 4600ml

Therefore, the vital capacity will be 4600ml.

Two pyruvate molecules form the final product of glycolysis, which begins with glucose and two ATP molecules and two NADH molecules are gained by the cell as a net result.

The first half of the process requires the utilization of two ATP molecules to set up the six-carbon ring for cleavage. But since this pathway is starting from fructose 1,6-bisphosphate, the utilization step is omitted thus four molecules of ATP and two molecules of NADH are produced in total.

Explanation:

Because you are dealing with volume and temperature, you need to Charles' Law to find your missing value. The equation looks like this:

V₁ / T₁ = V₂ / T₂

In this equation, "V₁" and "T₁" represent the initial volume and temperature. "V₂" and "T₂" represent the final volume and temperature. You can plug the given values into the equation and simplify to find the final volume of the gas.

V₁ = 10,000 L                 V₂ = ? L

T₁ = 20 °C                       T₂ = 25 °C

V₁ / T₁ = V₂ / T₂                                             <----- Charles' Law equation

(10,000 L) / (20 °C) = V₂ / (25 °C)                <----- Insert values

500 = V₂ / (25 °C)                                        <----- Divide 20 from 10,000

12,500 = V₂                                                 <----- Multiply both sides by 25
