How do secondary succession differ from the primary succession

Chemistry
1 answer:
OLEGan [10]3 years ago
3 0
Primary succession occurs following an opening of a pristine habitat, for example, a lava flow, an area left from retreated glacier, or abandoned strip mine. In contrast, secondary succession is a response to a disturbance, for example, forest fire, tsunami, flood, or an abandoned field

nydimaria [60]

Organometallic Chemical reaction is a Grignard reaction. The critical intermediate (which can be isolated and enables the final product) is the formation of a carbon bond.

The Grignard Reaction is an organometallic chemical reaction that mostly produces C-C bonds. When organic molecules are combined with the Grignard reagent, the Grignard reaction occurs (Rmgx).

The Grignard Reaction is the conversion of an aldehyde or ketone into secondary or tertiary alcohol by the addition of an organomagnesium halide (Grignard reagent). A primary alcohol is produced when formaldehyde and oxygen react.

Alcohol and water molecules have acidic hydrogen atoms that Grignard reagents quickly react with. A proton substitutes the halogen in a Grignard reaction with water, producing an alkane as the end result. Therefore, the Grignard reagent offers a two-step process for changing a haloalkane into an alkane.

What kind of intermolecular forces act between a sodium cation and an ammonia molecule? Note: If there is more than one type of
Reil [10]

Answer:

Ion-dipole forces

Explanation:

Na⁺ is a cation, that is, an ion with a positive charge.

NH₃ has polar covalent bonds (due to the difference in electronegativity between nitrogen and hydrogen). According to the VESPR theory, it has a trigonal pyramidal shape with a lone pair. As a consequence, it has a net dipole moment and the molecule is polar.

The intermolecular forces between Na⁺ (ion) and NH₃ (dipole) are ion-dipole forces.

Molecular formula of sodium sulphate from Criss cross method​
uranmaximum [27]

Answer:

Na2SO4

Explanation:

In the crisscross method, we can write the correct formula for an ionic compound by crossing over the numerical value of each of the ion charges to now serve as the subscript of the oppositely charged ion. Subsequently, the signs of the charges are dropped and the correct formula of the ionic substance is obtained.

For sodium sulphate;

Na ^+        SO4^2-

By crisscrossing and dropping the signs to obtain the subscripts we now have;

Na2SO4
