His revisions proved the importance of the atomic number and acknowledged why some of the elements seemed like they were out of place, even though they were in the right place.
Answer:
Coulomb's law, mathematical description of the electric force between charged objects. Formulated by the 18th-century French physicist Charles-Augustin de Coulomb, it is analogous to Isaac Newton's law of gravity.
Explanation:
Soo yeah I think this can help you
If the ion is named by (element-name) + ion, it is the element with a positive charge.
This means:
Sodium ion: Na(1+)
Aluminum ion: Al(3+)
If the ion is named by (element-prefix)+ide, then it has a negative charge.
This means:
Chloride: Cl(1-)
Nitride: N(3-)
Finally, if it has roman numerals after the name, that is the amount of positive charge the ion has.
Therefore:
Iron (II): Fe(2+)
Iron(III): Fe(3+)
<span>To find the balanced molecular equation, we need to find the symbols for each element and their charges and then balanced the equation. This comes out to:
Al(OH)3(aq) + 3HBR(aq) ---> AlBr3(aq) + 3H2O(l)
The net ionic equation is adding the charges and separating them into basic components.
Al3+ + 3OH- + 3H+ + 3BR- --> Al3+ + 3Br + H3O+
We can cancel out the aluminum and bromine to get:
3OH-(aq) + 3H+(aq) --> 3H2O(l)</span>
