Kinetic Theory: Tutorial
Activity
In this activity, open the Gas Properties simulation and follow the instructions provided with the questions below.
Part A
Using the controls along the right side of the simulation, under "Options," check the second box to select the temperature of the new particles
Then move the slider at the bottom to its lowest setting (50 K). Next, choose temperature as your constant parameter at the top. In the "Gas in
Chamber" box, add "light species" particles until about 200 are in the box. Finally, quickly add about 20 "heavy species" particles to the box.
Carefully observe how they spread across the chamber through time. What do you think causes the heavy particles to spread throughout the
chamber? What can you say about the direction of their movement?
Answer:
The heavy particles move across the chamber because of the diffusion property of gas particles. The particles move in straight lines and change directions only when they collide with other molecules or the walls of the chamber.

Al colocar unos trocitos de zinc en un tubo de ensayo, agregamos 2 mL de acido clorhídrico. El Zinc sustituye el hidrogeno del acido para formar una sal (ZnCl2) con el cloro Zn+2HCl-- ZnCl2 +H2 El nombre correcto de esta sal en la nomenclatura sistemática es
Answer:
DICLORURO DE ZINC
Explanation:
La ecuación es:
Zn (s) + 2HCl (aq) → ZnCl₂ (aq) +H₂ (g)
El zinc reacciona en una reacción redox con el acido clorhídrico para formar una sal y liberar el hidrogeno gaseoso.
Se trata de una reacción redox porque el hidrógeno se reduce (disminuye el numero de oxidación, de -1 a 0, en su estado fundamental), mientras que el Zn se oxida (el numero de oxidación aumenta de 0 a +2).
Como la sal se forma con dos atomos de cloro, se denomina dicloruro por lo que el nombre correcto de la sal en nomenclatura sistemática es:
- DICLORURO DE ZINC

What mass of solute will dissolve in 100 grams of water at the following temperatures?
KCl at 80ºC
NaCl at 90ºC
NaNO3 at 10ºC
Answer:
D) NaNO3 at 10 °C
Explanation:
In this case, to know this, we need to watch the solubility curve of each compound to know which one is saturated or unsaturated in this case.
As you can see in the curve attached, let's analyze first what is an unsaturated solution.
An unsaturated solution is a solution where the quantity of solvent is in excess and the solute is completely dissolved in solution leaving no remains. This depends on the temperature of course. The solubility of one compound vary with the increase or decrease of temperature.
As you can see in the graph attached, what happens to the KCl? we can see that a 40 °C, you just need around g of solute to be dissolved, and be saturated so, this is not the correct choice.
If you watch NaCl, has similar behavior. You just need about 35 g of solute to be saturated.
Finally, the KNO₃ just need 60 g of solute to be dissolved in the solution, completely.
In the case of NaNO 10°C, we can see that at 40 °C it's not touching the curve, so we can assume that this is an unsaturated solution and it would be the correct choice.

Answer:
I'm feeling nice today so heres the answer
Explanation:
In the portion of the cell membrane shown in the diagram, the arrow indicates the process of active transport.
Explanation:
Active transport is one of the mechanisms of transmembrane transport, which involves the use of energy. The diagram (see image) shows the hydrogen (H⁺) output from the cytoplasm to the extracellular space, through an H⁺ pump —consuming ATP— which represents an active transport process.
The hydrophobic nature of the cell membrane prevents the free passage of hydrosoluble elements or ions, as H⁺, so they require the use of active transport to pass through it.
The other options presented are not correct, because
Respiration is a process that occurs in the mitochondria.
Diffusion is a passive transport process that does not require energy.
Cellular recognition depends on membrane proteins that act as specific receptors.

1. How many joules are required to melt 338. grams of ice?
2. How many joules are required to convert 418 grams of boiling water into steam?
3. How many joules are required to convert 150. grams of boiling water into steam?
4. How many joules are required to convert 42.0 grams of boiling water into steam?
5. How many joules are required to heat 422 grams of steam from 110.0 0C to 135.0 0C?
Answer:
1. 111.54 kJ
2. 944.68 kJ
3. 339 kJ
4. 94.92 kJ
5. 21.0578 kJ
Explanation:
1. The heat required to melt a given quantity of ice is known as the latent heat of fusion, [tex]L^{\circ}_F[/tex], of ice
[tex]L^{\circ}_F[/tex], of ice = 330 J/g
The heat required to melt a given mass of ice = Mass of ice, m × latent heat of fusion, [tex]L^{\circ}_F[/tex], of ice
The heat required to melt 338 grams of ice = 338 g × 330 J/g = 111,540 J = 111.54 kJ
2. The latent heat of vaporization, l, of water = 2260 J/g
The heat required to convert, m grams of water to steam at
The heat required to convert 418 grams of boiling water into steam = 418 g × 2260 J/g = 944680 J = 944.68 kJ
3. To convert 150 grams of boiling water to steam, we have;
Heat required = 150 g × 2260 J/g = 339,000 J = 339 kJ
4. To convert 42.0 grams of boiling water to steam, we have;
Heat required = 42.0 g × 2260 J/g = 94,920 J = 94.92 kJ
5. The specific heat capacity of steam is 1.996 J/(g·°C)
The heat, Q, required to raise a given mass, m, of steam by Δt °C is given as follows;
Q = m × c × Δt
The heat required to raise the temperature of 422 grams of steam from 110.0 °C to 135.0 °C is therefore;
Q = 422 g × 1.996 J/(g·°C) × (135.0 °C - 110.0 °C) = 21057.8 J
The heat required to raise the temperature of 422 grams of steam from 110.0 °C to 135.0 °C = 21057.8 J = 21.0578 kJ
How much hydrogen reacts with 32 g of oxygen to produce 34 g of hydrogen peroxide. help and thxsss so much
Answer: the answer is 2g because you subtract 32-34 and get 2 and add the get so 2g
Explanation:
2 g of hydrogen reacts with 32 g of oxygen to produce 34 g of hydrogen peroxide.
To determine the amount of hydrogen that reacts with 32 g of oxygen to produce 34 g of hydrogen peroxide ([tex]H_2O_2[/tex]), we need to apply stoichiometry.
First, we find the molar masses:
Molar mass of oxygen ([tex]O_2[/tex]) = 16 g/mol
Molar mass of hydrogen peroxide ([tex]H_2O_2[/tex]) = 34 g/mol (given)
Next, we calculate the number of moles for oxygen and hydrogen peroxide:
Moles of oxygen = mass/molar mass = 32 g / 16 g/mol = 2 moles
Moles of hydrogen peroxide = mass/molar mass = 34 g / 34 g/mol = 1 mole
Since hydrogen peroxide has two hydrogen atoms, it requires twice the moles of hydrogen. Therefore, the moles of hydrogen required are also 2 moles.
Finally, we convert the moles of hydrogen to grams:
Mass of hydrogen = moles × molar mass = 2 moles × 1 g/mol = 2 g
So, 2 g of hydrogen reacts with 32 g of oxygen to produce 34 g of hydrogen peroxide

And was that really—was it really a SHEEP that was sitting on the other side of the counter? Rub as she could, she could make nothing more of it: she was in a little dark shop, leaning with her elbows on the counter, and opposite to her was an old Sheep, sitting in an arm-chair knitting, and every now and then leaving off to look at her through a great pair of spectacles.
“What is it you want to buy?” the Sheep said at last, looking up for a moment from her knitting.
“I don't QUITE know yet,” Alice said, very gently. “I should like to look all round me first, if I might.”
“You may look in front of you, and on both sides, if you like,” said the Sheep: “but you can't look ALL round you—unless you've got eyes at the back of your head.”

So u separated Sand and salt from a mixture through evaporation and filtration. Now what is your observations and decision?
Answer:
When two or more substances, that do not react chemically, are blended together,
the result is a mixture in which each component retains its individual identity and
properties.
The separation of the components of a mixture is a problem frequently encountered
in chemistry. The basis of the separation is the fact that each component has a
different set of physical and chemical properties. The components are pure substances
which are either elements or compounds. Under the same conditions of pressure and
temperature, the properties of every sample of a pure substance are identical. Each
sample melts at the same temperature, boils at the same temperature, has the same
solubility in a given solvent, etc.

Ajay bought bottle that was labelled as distilled water. He suspected it to be tap water. What test he could use without adding any chemical in it to find out for sure?
Answer:
Ajay should pass electric current through the water and connect a bulb to the circuit. If the bulb glows, it means that the water is tap water or else, it is distilled water.
Explanation:
This is because tap water contains little impurities like ions of some salts etc., which help in the conduction of electricity. But, distilled water is pure water and doesn't have any ions present in it. So, it doesn't conduct electricity.
Hope this helped
Ajay can test the distilled water by performing the electricity conduction test.
Distilled water has been the water that has an absence of ions and electrolytes. It has been a poor conductor of electricity.
The tap water has been constituted with minerals, electrolytes, and impurities, which results in the addition of conductivity to the water.
To test whether the water has been distilled or not, the circuit test can be performed The water has dipped wires connected with a battery and a bulb. the distilled water is a poor conductor did not allow the bulb to glow. However, with tap water bulb glow.
Thus, to test the water to be distilled or tap, the electricity conduction test has been performed.

What is the best definition for the freezing point of a substance? *
It is the temperature at which a substance become cold.
It is the temperature at which a substance changes from a gas to a liquid
It is the temperature at which a substance changes from a liquid to a solid.
Answer:
It is the temperature at which a substance changes from a liquid to a solid.
Have a good day!
The temperature at which a substance changes from a liquid to a solid is called its freezing point. Hence, option d is the correct definition of freezing point.
What is freezing point?Freezing point is a physical property of a substance which measures the temperature at which its liquid state converts to solid state where, the two phases are in equilibrium.
For example, water freezes at 0 degree Celsius to form ice. Hence, 0°C is the freezing point of water. The freezing point of substance is affected by the bond type, molecular weight, temperature and pressure as well the impurities if any.
The more the intermolecular forces between the molecules, more easy to convert it into solid. Hence, the freezing point will be lower. If there is any impurities present, the freezing point depression will occurs.
