You have to use density=mass/volume formula:


3.97= \frac{x}{575}

Solve for x and you get 2282.75 grams

Please help me with this: Create 20 bullet points specifically about energy exchanges in Earth's systems. Also, it doesn't have
raketka [301]

The below is about the energy exchanges in earth systems.                                                                                                          

<u>Explanation</u>:

  • Energy exchanges in earth systems are of many types.  The earth systems are atmosphere, geosphere, stratosphere, hydrosphere, and biosphere. All these earth systems exchange energy with each other.
  • The earth gains energy reflected from the sky. It converts that energy back to space. That energy is equally given to all the planets in the sky.
  • Each planet will absorb that energy and radiate heat. This heat is absorbed by all the places on the earth. So this is the energy exchange in the earth systems.

Write the condensed ground-state electron configurations of these transition metal ions, and state which are paramagnetic:
Zinaida [17]

The electron configuration of  V³⁺ is [Ar]3d^2. The ion is paramagnetic because it has two unpaired electrons

<h3>What is paramagnetic?</h3>
  • A weak magnetic field supplied externally can weakly attract some materials, which then create internal magnetic fields that are directed in the same direction as the applied magnetic field. This phenomenon is known as paramagnetic.
  • Diamagnetic materials, in contrast, are attracted to magnetic fields and produce induced magnetic fields that are directed in the opposite direction from the applied magnetic field.
  • The majority of chemical elements and some compounds are considered to be paramagnetic materials.
  • Paramagnetic materials have a relative magnetic permeability that is somewhat more than 1, which makes them attracted to magnetic fields.
  • The applied field induces a linearly decreasing magnetic moment that is relatively weak.
  • Modern experiments on paramagnetic materials are frequently done with a sensitive analytical balance since it typically requires a sensitive analytical balance to identify the effect.
