Answer:
The heat of vaporization describes how much energy is needed to separate these bonds. Water has a high heat of vaporization because hydrogen bonds form readily between the oxygen of one molecule and the hydrogens of other molecules. These bonds hold the molecules together.
Explanation:
Answer:
9945.6 J
Explanation:
Amount of heat = Mass * Heat Capacity * Temperature Change
Heat capacity of Water = 4.2 J/gC
Amount of heat = 64 * 4.2 * (69 - 32)
Amount of heat = 64 * 4.2 * 37
Amount of heat = 9945.6 J
Those are basically molecular formula. Which is Table sugar or cane sugar. Generally called sucrose.
The answer to this question is 6.25ml
To answer this question, you need to calculate the azithromycin drug doses for this patient. The calculation would be: 25kg * 10mg/kg/d= 250mg/d
Then multiply the doses with the available drug. It would be:
250 mg/d / (200mg/5ml)= 6.25ml/d
Answer:
The correct answer is option C
Explanation:
According to Heisenberg's principle "At the instant of time when the position is determined, that is, at the instant when the photon is scattered by the electron, the electron undergoes a discontinuous change in momentum. This change is the greater the smaller the wavelength of the light employed, i.e., the more exact the determination of the position. At the instant at which the position of the electron is known, its momentum therefore can be known only up to magnitudes which correspond to that discontinuous change; thus, the more precisely the position is determined, the less precisely the momentum is known".
Hence, this principle made scientists to realize that electrons could not be located in defined orbits which a contradictory of Bohr's model.
