What radionuclides is used in diagnosis of atherosclerosis

1 answer:

8 0

Answer: technetium-99.

Explanation:

This is not an answer that you can look for in a book.

You need to do some research.

You can fiind the abstract of the article titled Molecular imaging of atherosclerosis using a technetium-99m-labeled endothelin derivative.

The conclusion of this scientific article is that labeling with the radiosotope Tc - 99 iis feasibele to visualize the effects of an experiment inducing atherosclerosis, which gives the answer to the question posted.

An insulated container contains 0.3 kg of water at 20 degrees C. An alloy with a mass of 0.090 kg and an initial temperature of

Lorico [155]

Answer:

The specific heat of the alloy is 2.324 J/g°C

Explanation:

Step 1: Data given

Mass of water = 0.3 kg = 300 grams

Temperature of water = 20°C

Mass of alloy = 0.090 kg

Initial temperature of alloy = 55 °C

The final temperature = 25°C

The specific heat of water = 4.184 J/g°C

Step 2: Calculate the specific heat of alloy

Qlost = -Qwater

Qmetal = -Qwater

Q = m*c*ΔT

m(alloy) * c(alloy) * ΔT(alloy) = -m(water)*c(water)*ΔT(water)

⇒ mass of alloy = 90 grams

⇒ c(alloy) = the specific heat of alloy = TO BE DETERMINED

⇒ ΔT(alloy) = The change of temperature = T2 - T1 = 25-55 = -30°C

⇒ mass of water = 300 grams

⇒ c(water) = the specific heat of water = 4.184 J/g°C

⇒ ΔT(water) = The change of temperature = T2 - T1 = 25 - 20 = 5 °C

90 * c(alloy) * -30°C = -300 * 4.184 J/g°C * 5°C

c(alloy) = 2.324 J/g°C

The specific heat of the alloy is 2.324 J/g°C

In what direction does thermal energy transfer?

11Alexandr11 [23.1K]

Answer:

Either direction

Explanation:

If you cook food it would go from cold to hot. If you were to put a drink in the fridge it would go from hot to cold. So it is either direction.

How many numbers of atoms there are in 1.14 mol of (SO3)

Pachacha [2.7K]

called the Avogadro number

N(A)= 6.02 x 10^23 mol^-1

1 mole of SO3 will contain 6.02 x 10^23 mol^-1 of SO3 molecules.

thus, 1.14moles will contain;

= 1.14mol x [3mol O/1mol SO3] x [6.02 x 10^23

atoms O/1mol O]

= 2.05884 x 10^24 oxygen atoms

= 1.14mol x [1mol S/1mol SO3] x [6.02 x 10^23

atoms O/1mol O]

= 6.8628 x 10^23 sulfur atoms

hope this helps:-)
