What is the main difference between the Bohr model and the electron cloud model of the atom.
leonid [27]
Electron cloud is an informal term in physics. It is used to describe where electrons are when they go around the nucleus of an atom. The electron cloud model is different from the older Bohr atomic modelby Niels Bohr. Bohr talked about electrons orbiting the nucleus.

Classify the following pieces of matter:<br> bronze<br> pure water<br> tap water<br> trail mix
drek231 [11]

Answer:

bronze - solid

pure water - liquid

tap water - liquid

trail mix - solid

Explanation:

There are 4 classes of matter based on the characteristics of their molecules:

  • Solids
  • Liquids
  • Gases
  • Plasma

The molecules in solids are tightly packed together and are more or less fixed about a point with very little of no movement. The molecules in liquids are less tightly packed and are able to take the shape of their containers. The molecules in gases are loosely packed and compressible. They can take the shape of containers as well as expand to a container due to their loosely packed molecules.

Plasma molecules neither have shape nor volume but are able to produce both magnetic and electric currents as well as respond to electromagnetic fields.

<em>Hence</em><em> bronze </em><em>has all the characteristics of a </em><em>solid</em><em>, </em><em>pure and tap water</em><em> both have the characteristics of a </em><em>liquid</em><em>, while </em><em>trail mix </em><em>can be considered a </em><em>solid</em><em>. </em>

The following questions involve the quantities of some materials you will be using in the calorimetry lab. Keep a copy of your a
Dovator [93]

Answer:

0.075 moles

Explanation:

 Molarity = Mass/ Molar Mass*1000/Volume(ml)

Mole = Mass/ Molar mass

Given

  Molarity = 1.50 moles/ml

  Volume = 50 ml

∴ moles = Molarity*Volume/1000

              =1.50 *50  / 1000

              =0.075 moles
