Ask 3 questions that will help you better understand the coronavirus

Chemistry

lord [1]3 years ago

1: China is agreeably a third world country because they do not know what they should eat, they think that beating an animal and causing it pain and suffering makes the meat taste better which is very, very unjust and cruel. This disease was started where a Bio-Disease plant was, and considering coronavirus is spreading so fast and killing so many people, ( not unlike the swine flu that ALSO originated in China ) This indicates it is very possible that this disease could have been engineered. ( not unlike the swine flu either )

2: The person itself is smart, people are stupid, fearmongering, and have been weakened through the years. The moment the media said there was a pandemic, everyone ran to the nearest convenience store to buy toilet paper, then they locked themselves in their houses because people said to do so, they bought surgical masks ( that only help you if you have secondary breathing problems, because you go to take them off and touch your face ) that they HEARD will help them. MY opinion is do what makes YOU feel comfortable, you can't help other people, but you can help yourself.

3: I don't exactly understand this question, so if you could rewrite this part I could give you an answer.

Hope this helps, if not, comment below please!!!

Which experimental feature of the MALDI-MS technique allows the separation of ions formed after the adduction of tissue molecule
34kurt

Answer:

The experimental feature of the MALDI-MS technique which allows the separation of ions formed after the adduction of tissue molecules:

B) Velocity of ions depends on the ion mass-to-charge ratio.

Explanation:

  • The option a is not correct as distance traveled by ions doesn't depend upon the ion charge rather it depends upon time for which you leave the sample to run.
  • The  option b is correct as velocity of ions depends on the ion mass-to-charge ratio because separation is done due to mass to charge ratio feature.
  • The option c is incorrect as time of travel is not inversely proportional to the ion-to-mass ratio because the ion will move across the gel until you stop the electric field.
  • The option d is not correct as electric field between MALDI plate and MS analyzer is though uniform but this feature doesn't allow the separation of ions.

The freezing point of water H2O is 0.00°C at 1 atmosphere. A nonvolatile, nonelectrolyte that dissolves in water is urea. If 13.
Trava [24]

Answer:

Molality = 1.46 molal

The freezing point of the solution = -2.72 °C

Explanation:

Step 1: Data given

The freezing point of water H2O is 0.00°C at 1 atmosphere

urea = nonelectrolyte = van't Hoff factor = 1

Mass urea = 13.40 grams

Molar mass urea = 60.1 g/mol

Mass of water = 153.2 grams

Molar mass H2O = 18.02 g/mol

Kf = 1.86 °C/m

Step 2: Calculate moles urea

Moles urea = mass urea /molar mass urea

Moles urea = 13.40 grams / 60.1 g/mol

Moles urea = 0.223 moles

Step 3: Calculate the molality

Molality = moles urea / mass water

Molality = 0.223 moles / 0.1532 kg

Molality = 1.46 molal

Step 4: Calculate the freezing point of the solution

ΔT = i * Kf * m

ΔT = 1* 1.86 °C/m * 1.46 m

ΔT = 2.72 °C

The freezing point = -2.72 °C
