list four factors that affect rate according to the collision model

Answers

Answer 1

The four factors that affect rate according to the collision model are concentration, temperature, surface area, and presence of a catalyst.


One factor that affects rate is concentration. When the concentration of reactants increases, there are more molecules present in a given volume, increasing the likelihood of collisions. This results in a higher rate of reaction as there are more chances for successful collisions.

Another factor is temperature. When temperature increases, molecules gain kinetic energy and move faster, increasing the frequency of collisions. Additionally, higher kinetic energy increases the likelihood of successful collisions, resulting in a higher rate of reaction.

Surface area is also a factor that affects rate. When the surface area of a reactant is increased, more of the reactant is exposed, increasing the number of collisions and resulting in a higher rate of reaction.

Finally, the presence of a catalyst can greatly affect the rate of a reaction. Catalysts lower the activation energy required for a reaction to occur, increasing the likelihood of successful collisions and resulting in a higher rate of reaction.

In a lab, a scientist mixes a purple powder-like substance and a clear liquid together. The scientist observes that the two substances begin combining together, and he notices a gas begin to bubble out of the mixture. Did the scientist witness a chemical reaction? Why or why not?

Answers

yes he witnessed a chemical reaction because the substances combining caused a gas to form, creating a new substance

The scientist witnessed a chemical reaction because a gas was evolved when the two substances were mixed.

A chemical reaction is the same as a chemical change. When a chemical change occurs, atoms recombine to form new substances. Certain occurrences may accompany a chemical reaction such as;

Change in colorEvolution of gasAppearance of a solid in an aqueous phase reactionSudden change in the temperature of the system.

When the scientist mixed purple powder-like substance and a clear liquid together, he noticed that a gas began to bubble out of the mixture. This implies that new substance has been formed so a chemical reaction has taken place.

Answers

Answer:

Explanation:

After various studies and experiments conducted on Pluto's moon, Charon it has been determined that it gets to minus 459.67 degrees Fahrenheit which would be equivalent to minus 273.15 degrees Celsius. This is the coldest temperature that scientists have registered for Charon. This temperature is nearing absolute zero and puts it colder than Pluto itself since Pluto's temperature is believed to get to minus 400 degrees Fahrenheit which is equivalent to minus 240 degrees Celcius.

Answers

Answer:

Atom, cell, dust particle, ant, ping pong ball

Explanation:

Firstly, atoms make up all matter, including each of the items on that list. The only things smaller than atoms are the parts of the atom itself, protons, neutrons and electrons. Because none of those are on that list, atoms have to be the smallest. Next smallest is the cell. Cells are made up of atoms, but they also in part make up dust. You can see a dust particle with the naked eye, but in order to see a cell you must use a microscope. Thus, cells are smaller than dust particles. Next is an ant. Obviously, an ant is bigger than a speck of dust, and is made up of cells and atoms. Lastly all you have is the ping pong ball, which is much larger than the rest of the items. Hope this helps!

All matter, including each thing on the list, is made up of atoms. The protons, neutrons, and electrons that make up an atom are the only particles smaller than atoms.

Thus,  Atoms must be the tiniest object because none of those are included in that list. The cell is the next smallest. Atoms make up cells, but dust also makes up a portion of them.

A dust particle can be seen with the unaided eye, but a microscope is required to see a cell.

Cells are hence smaller than dust particles. An ant comes next. Of course, an ant is composed of cells and atoms and is larger than a particle of dust.

Thus, All matter, including each thing on the list, is made up of atoms. The protons, neutrons, and electrons that make up an atom are the only particles smaller than atoms.

The pH of a solution is 8. Some hydrochloric acid is added to the solution. Suggest the pH of the solution after mixing. pH=.......??

Answers

Answer:

By adding acid to hydrogencarbonate you create a large concentration of CO2 in solution causing the solution to be highly supersaturated. This keeps the pH down as CO2 is in equilibrium with carbonic acid. During the day long mixing the excess CO2 strips off and as acid leaves the solution the pH increases.

Explanation:

Hope it helps

A solution with a pH of 8 will have its pH reduced with the addition of hydrochloric acid.

What is pH?

It is the degree of acidity or alkalinity of solutions.

pH ranges from 0 to 14 with 7 being a neutral pH. Any pH below 7 is acidic while above 7 is basic.

Thus, a pH of 8 is basic and the addition of hydrochloric acid will reduce it towards 7 or even below it.

18.985
Isotope-C
14.0
19.982

Answers

Answer:

18.58

Explanation:

From the question given above, the following data were:

Isotope A:

Abundance of A = 54%

Mass of A = 17.984 amu

Isotope B:

Abundance of B = 32%

Mass of B = 18.985 amu

Isotope C:

Abundance of C = 14%

Mass of C = 19.982 amu

Average atomic mass =?

AVERAGE = [(Mass of A × A%)/100)] + [(Mass of B × B%)/100] + [(Mass of C × C%)/100]

AVERAGE = [(17.984 × 54%)/100] + [(18.985 × 32%)/100] + [(19.982 × 14%)/100]

= 9.71136 + 6.0752 + 2.79748

= 18.58

Therefore, the average atomic mass of the isotope is 18.58 amu

this problem

Answers

Answer:

800.3 Kelvin

Explanation:

127°C = 400.15 Kelvin   (because 127 + 273.15)

Charles Law:

[tex]\frac{V1}{T1} = \frac{V2}{T2}[/tex]   Thus, [tex]\frac{10.0 L}{400.15 K} = \frac{20.0 L}{T2}[/tex]

Then, work out the math algebraically.  

T2 = 20.0 / (10.0/400.15)

= 20.0 / 0.02499...

= 800.3 Kelvin

This is assuming the pressure remains constant.

Fire ants move in to a new environment with the lizards.what will most likely happen to the lizard population over the next several years

Answers

Answer:

Some lizards in the eastern U.S. have adapted to invasive fire ants -- which can bite, sting, and kill lizards -- reversing geographical trends in behavioral and physical traits used to avoid predators. A new study describing this reversal appears online on November 29, 2018, in the journal Global Change Biology and reveals that new environmental challenges can override the historical influences that originally determined geographical trends in traits.

"Rapid environmental change, be it from changing climate or the introduction of invasive species, is putting a lot of pressure on native species," said Christopher Thawley, graduate student at Penn State at the time of the study and first author of the paper. "Usually when researchers look at how native species might respond to these kinds of threats, they might measure one characteristic of the animal and at one or a few sites. In this study, we looked at three separate characteristics of eastern fence lizards from thirteen sites spanning a thousand miles and found that these lizards are capable of adapting in a concerted way to meet the threat of invasive fire ants, and in a relatively short time frame."
