Recall all the models you described in task 1. Think about the results each model would predict for the experiment with hydrogen
SpyIntel [72]

Answer:

Rutherford's theory laid the foundation upon which Bohr's model is founded. Rutherford established the fact that at the center of the atom, there is a nucleus whose radius is smaller than the radius of the atom. This nucleus is positively charged and most of the mass of the atom is concentrated there. Electrons move round this nucleus in orbits.

The experimental evidences of the Bohr's model shows that Rutherford's model was fundamentally correct. However, Bohr's model introduced the idea of quantization of the energy of electrons in an atom. The model went further to explain the spectra lines of the hydrogen atom.

cluponka [151]

Answer:

12,000 units of heparin are received by patient in 24 hours.

Explanation:

10,000 units of heparin in 1000ml of D5W.

Units of heparin in 1 mL = \frac{10,000}{1000}=10 units

Rate at heparin drip set at = 50 ml/hour

Units of heparin in 50 ml of solution = 50\teimes 10 units =500 units

500 units of heparin are received by patient in an every hour.So, in 24 hours patient will receive:

500units\times 24 = 12,000 units of heparin

12,000 units of heparin are received by patient in 24 hours.
