Answer:
D.
Explanation:
I just got it right in the test :)
The answer is common table salt. Looking at the chemical make up, putting an acid (I think chlorine) and and base (probably sodium) makes water (H20) and salt. So you answer would be salt
Answer : The correct net ionic equation is:

Explanation :
Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.
Net ionic equation : In the net ionic equations, we are not include the spectator ions in the equations.
Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.
The balanced molecular equation will be,

The complete ionic equation in separated aqueous solution will be,

In this equation, spectator ions are not present.
The correct net ionic equation is:

The hills and valleys decrease the height and speed of the ride. This means that the graph has a negative correlation.
By the way, I think you may have plotted your points incorrectly. The directions said to connect them all with a smooth line or curve.
Also, this is not high school chemistry. This is more likely to be elementary school science. Just make sure that you put your questions in the correct categories next time! :)
