The atomic clock is a procedure that uses the change rate of biomolecules to reason the time in ancient times when at least two living things veered. A device utilized by developmental scientists to gauge the rate of speciation utilizing changes in DNA.
Change in DNA/time = biological rate
<u>Answer:</u> A red color precipitate is formed of iron (III) carbonate. 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 potassium carbonate and iron (III) chloride is given as:
Balanced ionic form of the above equation follows:
As, potassium and chloride 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.
Iron (III) carbonate is a red colored solid which gets precipitated out.
The balanced net ionic equation for the above reaction follows:
Hence, a red color precipitate is formed of iron (III) carbonate. The net ionic equation is written above.
