<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>
The poly atomic ion formula for ammonium would be NH4+
.50 M KCl because 5% is the same as .05, which makes the .50M more concentrated.
<span>Every atom and molecule has its own chemical potential energy value since atoms and molecules are attracted to each other. Whenever atoms and molecules form ionic or covalent bonds, their individual potential energies are converted into heat or light energy. The heat or light energy is released as the bonds form. Atoms that form strong bonds have lower potential chemical energy levels and release little heat or light, while atoms that form weak bonds have higher potential chemical energy levels and release a lot of heat or light during the formation of chemical bonds.

Answer:
Explanation:
Oppositely charged particles attract each other, while like particles repel one another. Electrons are kept in the orbit around the nucleus by the electromagnetic force, because the nucleus in the center of the atom is positively charged and attracts the negatively charged electrons.
