O D. Chromatography separation

Answers

I believe distillation is used to separate solvents of different kind as long as it is heated to its boiling temp

The statement, that describes separation technique would most likely be used if a solvent were saved is "distillation separation."

What is separation technique?

Separation techniques are methods for separating two different states of matter, such as liquid and solid. Methods that employ variations in physical qualities to separate the components of a mixture, such as evaporation, distillation, filtration, and chromatography, can be used to physically separate the components of a mixture.

Simple distillation is a technique for removing a solvent from a solution. Water, for example, can be extracted from salt solution by simple distillation. If a solvent was saved, the separation procedure would most likely be used is distillation.

Calculate how many grams of oxygen form when 2.72 g of KCIOg reacts completely given the
following equation:
2 KCI03 (s)
- 2 KCI (s) + 302 (g)

Answers

1.06g

Please refer to the image attached.

You first find the number of moles (n) for KClO3 as you have been given the mass. So n = mass/Mr gives you the moles that is 0.022 mol

Next you use the ratio 2:3 as per the equation where it's 2KClO3 ---> 3O2 so you just cross multiply and get the moles for oxygen.

Now that you know the number of moles for oxygen, you can use the same moles equation that you used earlier to find the mass. mass=n×Mr and so you get the answer as 1.06g of oxygen.

Answer:

Explanation:

The permanent change in which a new substance is formed is called a chemical reaction.

For example:

i)Burning of wood

ii)Cooking rice

iii)Forming curd from milk

The burning of wood is a chemical reaction because it is a permanent change and it cannot be reversed. Once it is done, it is over it can't be done again. And in the case of example iii, the milk turns into curd by chemical reaction. A new substance i.e curd is formed from the milk.

The more solute is broken down in solution the less conductive the solutions is. True or False

Answers

Answer:

False.

Explanation:

If the answer to this question was true, then that would mean that the more the solute is broken down, the less it'll dissolve... and everyone know that this doesn't make sense. I hope I explained this is an easy manner so you could understand! Good luck! :)

The more solute is broken down in solution the more conductive the solutions is and the statement is False.

What effects the conductive nature of a solution?

Conductivity depends upon solvation of ions present in solution. Greater the solvation of ions, lesser is the conductivity.

Solvation is the process in which molecules of a solvent attract the particles of a solute.

The main forces in solvation are ion-dipole and hydrogen bonding attractions.

The more concentrated a solution is, the greater the conductivity measured (if the solute is a conductor in solution). This is because the higher the concentration of the solute, the more ions will be available to carry electric charge.

Therefore, the more solute is broken down in solution the more conductive the solutions is and the statement is False.

how many moles of methane are produced when 4.53 mol co2 reacts

Answers

The reaction formula CH4 + 2O2 → CO2 + 2H2O shows the oxidation of 1 mole of CH4 (Methane) will yield 1 mole of CO2 (Carbon Dioxide). Since 1 mole of CH4 will weigh 12g (for the Carbon) + 4g (1g for each Hydrogen) = 16g, then 32g of CH4 will correspond to 32g / 16g/mole = 2 moles. Therefore the oxidation of 2 moles of CH4 will yield 2 moles of CO2.

How many grams of each product is produced? How many grams of each reactant are left at the end of the reaction? What is the final pressure at the end of the reaction? (The final volume is 3.88L and the final temperature is 22.5C).

Answers

The ideal gas equation can be used to obtain the pressure, number of moles, volume and temperature of a gas.

What is the ideal gas equation?

The ideal gas equation gives the relationship between pressure, number of moles, volume and temperature.

To obtain the number of moles of PH3

PV = nRT

n = PV/RT

n = 0.80 atm * 1.50 L/0.082 atmL/Kmol * 298 K

n = 0.049 moles

Number of moles of O2

PV = nRT

n = PV/RT

n = 0.100 atm *  2.28L /0.082 atmL/Kmol * 293 K

n = 0.0095 moles

Fom the reaction equation;

4 moles of PH3 reacts with 8 moles of O2

0.049 moles of PH3 reacts with  0.049 moles * 8/4 moles

= 0.098

Hence O2 is the limiting reacatant.

Mass of P4O10 produced =

8 moles of O2 yields 1 mole of P4O10

0.0095 moles  of O2 yields 0.0095 moles  * 1 mole/8 moles

= 0.0012 moles

Mass of P4O10  = 0.0012 moles * 284 = 0.34 g

Mass of water;

8 moles of O2 yields 6mole of water

0.0095 moles  of O2 yields 0.0095 moles * 6 moles/8 moles

=0.0071 moles

Mass of water = 0.0071 moles * 18 g/mol = 0.13 g

Since 4 moles of PH3 reacts with 8 moles of O2

x moles of PH3 reacts with 0.0095 moles  of O2

x = 0.0048 moles

Moles of PH3 left over = 0.049 moles - 0.0048 moles = 0.0442 moles

Mass of PH3 left over = 0.0442 moles * 34 g/mol

= 1.5 g

No mass of O2 is left over because the limiting reactant is used up.

Total moles of gas left after the reaction = 0.0442 moles +  0.0071 moles = 0.0513 moles

P = nRT/V

P = 0.0513 moles * 0.082 atmL/Kmol * 295.5/3.88L

P= 0.32 atm'

Read the passage.Robots Are Cool, but AI is the FutureMany people dont realize that there is a difference between robotics and artificial intelligence (AI). While robots do use AI, the two fields are entirely separate. Robotics is concerned with the building of machines. These machines connect with the real world by using sensors, and they can be programmed to perform tasks. Additionally, robots usually operate independently or semi-independently. AI involves computer algorithms that can learn, perceive, problem-solve, understand human language, and use logic and/or reasoning.To clarify, a robot can be a human-operated machine arm that is used to weld car parts. AI can, without using the Internet, debate a human opponent on complex topics. Robots carry out instructions. AI mimics human intelligence.Robots are more a part of our everyday life than ever. They vacuum houses, build cars, perform operations, monitor homes, and assemble furniture. AI is a relatively new invention, but it will soon be a regular part of our lives. So, how will we use it?We already do!Virtual helpers on our mobile and home devices are one way in which AI has infiltrated daily life. They can operate electronics via voice command. We can ask them to turn lights and faucets on and off, lock and unlock doors, and order food, clothes, and other retail items. Or, we can have them operate smart devices so that they can open and run applications, translate foreign languages, and check email. In addition, we can use artificial intelligence to conduct a search or schedule appointments online, or to use devices to set an alarm or find directions. Audiobooks: A Case StudyAs these applications master the human language, AI will branch out into a variety of human endeavors, including the entertainment industry. Audiobooks (fiction and nonfiction narrated by authors and voiceover actors) are one of the largest-growing markets of the last three years. Once an afterthought of the publishing industry, audiobooks have become an increasingly profitable source of revenue for publishing companies. In 2018, about $940 million in audiobooks were sold24.5 percent more than the previous year. However, the process of creating audiobooks is laborious, tedious, and expensive. It can take a narrator several hours to read a single chapter of a book, depending upon its length. Multiply that by the number of chapters in a book, and it could take days to finish recording. Finally, the recorded audio must be edited, processed, mixed, and mastered. In the end, an audiobook can take over a month to produce. On top of that, publishers must pay everybody involved. It could cost thousands of dollars to create a final product.AI, however, is revolutionizing the process. Every day, AI algorithms learn how to speak like real human beings. They learn new words, languages, dialects, and accents. They can mimic natural breaths and pauses. Currently, AI can duplicate English spoken by a woman from India or a man from London. All anybody would need to do to produce an audiobook is feed the text into a computer. Instead of a week to create a final product, the performance could take an hour or two. The editing step would be unnecessary, so the audio could go straight to mixing and processing. With AI, the whole project could be completed in a fraction of the time it would take with humansat a fraction of the cost.Increasing the Quality of Human LifeReading all those books will naturally make AI smarter, and when it does, it could relieve humans from tedious chores. Cooking, cleaning, driving, shopping, teaching, and even farming could be managed by AI. Humanity could enter a time of unprecedented peace. This will allow people the freedom to do whatever they want. Did you always want to be a mountain climber, become a novelist, explore the galaxy, study languages, or learn how to make pottery? AI could not only allow it to happen but could also be a significant factor in successfully achieving those goals. Mountain climbers could use AI to choose the best routes, novelists could use AI to help develop plots, and students could use AI to increase comprehension and fine-tune skills. And those galaxy jumpers? Of course, AI would accompany them on their trips to the stars.There are many predictions as to when AI will become powerful enough to really take off and outperform humans in a variety of capacities. Some believe it will happen soon; others think it will take much longer. Right now, AI continues to impact human beings in a variety of positive ways, from technological innovation to economics to creativity. The prospects for the future are exciting!
