The following chemical reaction takes place in aqueous solution: ZnBr2(aq)+2 NaOH(aq) --Zn(OH),(s)+2 NaBr(aq)
Write the net ionic equation for this reaction.

.

Explanation:

Rewrite only the species that exist as ions. Those species typically include:

In this reaction, both and are salts. The state symbol "" suggests that both of these salts are soluble. Hence, both of these salts exist as ions and should be rewritten:

Similarly, the state symbol "" suggests that the base is also soluble:

On the other hand, the state symbol "" suggests that the base is a precipitate and is not soluble. Rather, the bonds within stay mostly intact, and this species would not exist as ions. Hence, do not rewrite when deriving the ionic equation for this reaction.

Hence, the ionic equation for this reaction would be:

.

Eliminate species that are present on both sides of the ionic equation to obtain the net ionic equation. A species should be eliminated if only if an equal number of this species are found on both sides of the ionic equation. Otherwise, subtract from the side with a larger number of that species.

For this reaction, the net ionic equation would be:

.

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
