C according to Earth's existing magnetic field

Explanation:

When new basalt forms along mid ocean ridges, they become magnetized according to the the earth's existing magnetic field. The magnetic minerals in basalt will align in the direction of the prevailing geomagnetic field of the earth.

  • The earth is like a bar magnet due to the magnetic field being produced by the movement of molten metallic materials in the outer core.
  • The effect of the magnetic field is felt globally as new magma are brought to the surface.
  • Magnetic minerals for example in basalt will align their domains in the direction of the existing or prevailing field.
  • This is used in studying paleomagnetism of a rock.

If an exothermic chemical reaction occurs, the surroundings become warmer. Where does this energy come from?
Elena L [17]

It comes to from the chemical reaction itself. Exothermic reaction release heat because the energy level of the products is lower than that of the reactants.  Therefore, the net enthalpy change of the reaction is negative (-), meaning heat or light (or any other form of energy) is released into the environment. An example of an exothermic reaction is the combustion of fuel.

Nitrobenzene contains 5 hydrogen atoms, 6 carbon atoms, 2 oxygen atoms, and 1 nitrogen atom. what is the chemical formula for ni
ollegr [7]

C₆H₅NO₂

<h3>Further explanation</h3>

Nitrobenzene contains:

  • 5 hydrogen atoms,
  • 6 carbon atoms,
  • 2 oxygen atoms, and
  • 1 nitrogen atom.

The chemical formula for nitrobenzene is C₆H₅NO₂.

Nitrobenzene is one of benzene derivatives, precisely including the type of monosubstituted benzenes.

The molecular structure of phenyl  \boxed{ \ C_6H_5- \ } is formed by removing one H atom from the benzene \boxed{ \ C_6H_6 \ } molecule. A substituent is bound to the C atom which loses the H atom so it is called monosubstituted benzene.

In the naming of monosubstituted benzenes, benzene is the parent name and the substituent is indicated by a prefix.

  • nitro is the substituent
  • benzene is the parent name

When benzene is reacted with a mixture of concentrated nitric acid and concentrated sulfuric acid, it yields nitrobenzene.

\boxed{ \ C_6H_6 + HNO_2 \ (with \ H_2SO_4 \ in \ 30^0C-40^0C) \rightarrow C_6H_5NO_2 + H_2O}

<u>Notes:</u>

  • Benzene and compounds having similar chemical properties to benzene are called aromatic compounds.
  • Benzene is a colorless, poisonous liquid with a specific odor. it dissolves in organic solvents in organic solvents such as alcohol, ether, and acetic acid. Benzene is also good for non-polar substances.
  • Nitrobenzene is used in the manufacture of aniline and other organic chemicals. Nitrobenzene is a pale yellow, oily, and highly toxic liquid with the odor of bitter almonds.

Which compound is a polar molecule and has a linear geometry
kirill115 [55]

Answer:

Linear molecule is a molecule in which atoms are deployed in a straight line (under 180° angle). Molecules with an linear electron pair geometries have sp hybridization at the central atom. An example of linear electron pair and molecular geometry are carbon dioxide (O=C=O) and beryllium hydride BeH2.
