<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.
The answer is 6 because the number of chlorine is 2 so if you have 6 moles of chlorine the answer is 6
Answer:
CaC2 + 2H2O → C2H2 + Ca(OH)2
thats it
Explanation:
Test it by checking it's hardness, texture, and how it stands against other substances.
Answer: Formation of precipitate indicates that there has been a chemical reaction.
Explanation:
Chemical reaction: It is defined as change in arrangement of the atoms so as to form a new substance.
Mixing of two clear solutions that is lead nitrate and potassium iodide gives out yellow solid precipitate of lead iodide with aqueous solution of potassium nitrate.

The physical evidence which indicates that chemical reaction has been taken place is formation of yellow solid precipitate of lead iodide ,(
).
