The thing to recognize here is the fact that you're dealing with a neutralization reaction that features sodium hydroxide,

NaOH

, a strong base, and hydrochloric acid,

HCl

, a strong acid.

This tells you that the two reactants will dissociate completely in aqueous solution to produce cations and anions. More specifically, you will have

NaOH

(

→

HCl

Now, when these two solutions are mixed, the hydroxide anions produced by the strong base and the hydrogen ions produced by the strong acid will neutralize each other to produce water.

The sodium cations and the chloride anions act as spectator ions because they are present on both sides of the chemical equation as ions.

You can tell that this is the case because sodium chloride,

NaCl

, one of the two products of the reaction, is soluble in aqueous solution.

So, the complete ionic equation will be

To get the net ionic equation, simply remove the spectator ions

SIDE NOTE You will sometimes see the hydrogen ion being replaced by the hydronium ion,

In this case, the dissociation of hydrochloric acid is represented by the chemical equation

HCl

The net ionic equation will now take the form

Answer from: Quest

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

plz give brainliest

Answer from: Quest

4- c, because all matter stays the same no matter what. it is still there. 5- b, because matter is known as mass. 6-c because, flammability is a chemical property. malleability is changing the shape of an object.
