I think it is B. Because A has nothing to do with chemical changes because any change takes an amount of time, C because in a mixture different compounds are involved, It could be D though but A new substance is produced in other changes too thus it must be B.
REVOLVE around the sun
the earth ROTATES on its axis which causes day and years but when you REVOLVE your causing years.
<u>Answer:</u> The net ionic equation is written below.
<u>Explanation:</u>
Net ionic equation of any reaction does not include any spectator ions.
Spectator ions are defined as the ions which does not get involved in a chemical equation. They are found on both the sides of the chemical reaction when it is present in ionic form.
The chemical equation for the reaction of calcium iodide and chromium (III) sulfate is given as:
Ionic form of the above equation follows:
As, chromium and iodide ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.
The net ionic equation for the above reaction follows:
Hence, the net ionic equation is written above.
That is approximately .63620 grams.
