The staff members working in Radiology department in hospitals, wear shoes with special soles. Justify

Chemistry
1 answer:
ella [17]3 years ago
6 0

Answer:

Radiology departments in hospitals use x-rays, MRIs, CT scans, etc. on a daily basis, meaning they are heavily exposed to radiation without protective equipment, and said exposure can cause cancer down the line and shorten their life significantly. To prevent this from happening, they give the radiologist (and the patient) with equipment with lead (and other materials) which reflects or absorbs the radiation from these scans, including shoes with special soles. These shoes are most likely worn due to the radiation left in the scanning room floors after scans. Radiologists also go to a special room with heavy radiation protection where they can activate and monitor the scan.

In which of the following cases will the LEAST time be required to arrive at equilibrium? K below refers to the equilibrium cons
mylen [45]

Answer: Option (4) is the correct answer.

Explanation:

It is known that equilibrium constant is represented as follows for any general reaction.

                 A + B \rightarrow C + D

                   K = \frac{[C][D]}{[A][B]}

As equilibrium constant is directly proportional to the concentration of products so more is the value of equilibrium constant more will be the number of products formed.

As a result, more is the time taken by the reaction to reach towards equilibrium. Whereas smaller is the value of equilibrium constant more rapidly it will reach towards the equilibrium.

Thus, we can conclude that cases where K is a very small number will require the LEAST time to arrive at equilibrium.

Problem PageQuestion A chemist makes of magnesium fluoride working solution by adding distilled water to of a stock solution of
igomit [66]

Answer:

5.37 × 10⁻⁴ mol/L

Explanation:

<em>A chemist makes 660. mL of magnesium fluoride working solution by adding distilled water to 230. mL of a 0.00154 mol/L stock solution of magnesium fluoride in water. Calculate the concentration of the chemist's working solution. Round your answer to 3 significant digits.</em>

Step 1: Given data

  • Initial concentration (C₁): 0.00154 mol/L
  • Initial volume (V₁): 230. mL
  • Final concentration (C₂): ?
  • Final volume (V₂): 660. mL

Step 2: Calculate the concentration of the final solution

We want to prepare a dilute solution from a concentrated one. We can calculate the concentration of the final solution using the dilution rule.

C₁ × V₁ = C₂ × V₂

C₂ = C₁ × V₁ / V₂

C₂ = 0.00154 mol/L × 230. mL / 660. mL = 5.37 × 10⁻⁴ mol/L

Glucose, c6h12o6, is used as an energy source by the human body. the overall reaction in the body is described by the equation
Art [367]
Glucose is carbohydrate and a simple sugar that is very important to the human body.

Energy is produced for the cells in the body through the process of metabolism which oxidizes glucose to water, carbon dioxide, and some nitrogen compounds. 

The general chemical reaction equation for metabolism is:
 
C6H12O6 + 6O2 ---> 6CO2 + 6H2O
