Both the Sun and the Earth are sources of heat that power an interconnected set of dynamic systems (lithosphere, hydrosphere & cryosphere, atmosphere, biosphere).
Within the Sun, heat is transferred by radiation and convection, which involves circulation of hydrogen ions. Within the Earth heat is transferred by conduction and convection, which involves circulation of silicates in the mantle and the crust, and by the circulation of iron in the liquid outer core. On the surface of the Earth and the atmosphere, heat emanating largely from the Sun is transferred by convection, which involving the circulation of water and carbon. Both the Sun and the Earth and their atmospheres are layered. Both systems evolve and change.
Answer:
Explanation:
Hello,
In this case, the undergoing chemical reaction is:
Thus, since lead (II) nitrate is in excess, we can directly compute the moles of lithium nitrate by applying the 1:2 molar ratio between them in the chemical reaction as well as the molar mass of Lithium Sulfate that is 110 g/mol for the stoichiometric shown below factor:
Finally, by using the Avogadro's number we are able to compute the molecules:
Best regards.
Talking about ions, a cation has a positive charge. That means a positive charge is gained by an atom that gives out electrons.
Answer:
There are two definitions for acid and base in chemistry.
Explanation:
There are different definitions of Acid and Base:
The <em>Arrhenius</em> definition sais that <u>acid</u> is every substance that increases the concentration of protons in water. Thus, a <u>base</u> is a substance that increase the concentration of oxydriles in water.
On the other hand, the <em>Bronsted</em> definition sais that an <u>acid</u> is a substance with the ability to give protons and a <u>base</u> is a substance with the ability to accept protons.
