When potassium iodide liquid is poured into lead nitrate solution (both clear solutions), a bright yellow solid, lead iodide, forms in a potassium nitrate solution. what are the signs that this is a chemical reaction? check all that apply. heat is produced. light is produced. heat is absorbed. bubbles appear. a precipitate forms. the color changes.

Potassium iodide is the chemical compound widely used as dietary supplement and for medications. The reaction between KI and lead (II) nitrate is an endothermic reaction because:

Double displacement reaction is observed in the KI and lead nitrate because the exchange of ions between both the reactants takes place. It is also an example of the precipitation reaction because the precipitate of lead iodide is formed.

The signs observed in the chemical reaction are:

Therefore, the color changes, heat absorption, and formation of precipitate are the signs present in the given chemical reaction.

To know more about chemical reaction, refer to the following:

the correct options are-

-a precipitate forms

-the color changes

Explanation:

hope it helps! correct on edge :)

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
