300 degrees Kelvin = 300 - 273 = 27 degrees Celsius.

So what you need to do is find out how many degrees Fahrenheit that is.

F = 9/5(27) + 32

F = 48.6 + 32

F = 80.6

You are at 55oF. You need to go from 55 to 80.6 or 25.6 degrees F.

Your closest answer is B. <<<<<< Answer

Answer:

B) increase the room temp by 26°F

Explanation:

From the given information:

Room temperature = 55 °F

Required temperature = 300 K

<u>Conversion from K to °F:</u>

F = 9/5(K-273) + 32\\\\For T = 300 K\\\\F = 9/5(300-273)+32 = 80.6F

The required temperature in °F = 80.6°F

Therefore, the lab temperature must be increased by:

(80.6-55)F = 25.6 F

Hitman42 [59]

For example, certain medications may influence the results of the test.

Drug test can show the presence of illicit or prescription drugs on hair samples, although the person has not used these drugs.

Some of false positive drug use is because of this medications: antihistamines, decongestants, antibiotics, antidepressants, analgesics and antipsychotics.

Which expression represents the ΔH for a chemical reaction in terms of the potential energy, PE, of its products and reactants?
densk [106]
2 - PE of products-PE of reactants.

You are trying to calculate the energy change that occurred from the start of the reaction (the reactants going in) to the end of the reaction (the products coming out). Therefore if there is more energy at the end, you will get a positive result from subtracting the PE of the reactants, and vice versa.
