Ionic bonds form between two or more atoms by the transfer of 1 or more electrons between atoms. Electron transfer produces negative ions called anions and positive ions called cations. ... In forming an chemical bond, the sodium atom, which is electropositive, loses its negatron to chlorine.
Explanation:
The potassium will donate one of its valence electrons
C i think is the ansower hope it helped
Answer:
C
Explanation:
Just look at the reactants.
2AgCl + BaBr2
The first reactant is made of 2 elements.
The second reactant is made of 2 elements.
It can't be a decomposition. At this level there is only one reactant made of 2 elements. Something like
2MgO ===> 2Mg + O2
is a decomposition. One compound breaking down into 2 elements Mg and O.
It can't be a combustion. One of the reactants in a combustion is oxygen. Those equations look like
C3H8 + 5O2 ==> 3CO2 + 4H2O
That would be what a combustion looks like
It can't be a single replacement. They look like
Mg + CuO ===> Cu + MgO
There are elements on both sides of the reaction.
that leaves a double replacement which I wrote about how you distinguish it.
