Adding potassium iodide to lead nitrate is it physical or chemical change?
This is a chemical change because a new compound, potassium nitrate, is formed through a chemical reaction between the potassium iodide and lead nitrate. Physical changes do not involve the formation of new substances.
Is the process of adding dish soap to water in a sink a physical or chemical change?
The process of adding dish soap to water in a sink is a physical change.
Is adding antifreeze to your radiator a chemical or physical change?
Adding antifreeze to your radiator is a physical change because the antifreeze retains its chemical composition and properties when mixed with the water in the radiator. It does not undergo a chemical reaction to form a new substance.
How can one effectively test for nitrate levels in water?
One can effectively test for nitrate levels in water by using a nitrate test kit, which typically involves collecting a water sample, adding reagents to the sample, and then comparing the color change to a color chart to determine the nitrate concentration.

Is adding silver nitrate to water a physical or chemical change?
When silver nitrate is added to water, it undergoes a physical change as it dissolves in the water. No new substances are formed during this process, so it is considered a physical change rather than a chemical change.
When adding silver nitrate to salt water does it undergone a chemical or a physical change?
anytime any elements/mixtures are placed together it is a chemical change... a physical change is if the silver nitrate is by itself and changed it physical appearance but is the same element (like if a human changes there clothes)
Adding potassium iodide to lead nitrate is it physical or chemical change?
This is a chemical change because a new compound, potassium nitrate, is formed through a chemical reaction between the potassium iodide and lead nitrate. Physical changes do not involve the formation of new substances.
Is the reaction between magnesium nitrate and potassium chromate chemical or physical what is the chemical equation for this reaction?
The reaction between magnesium nitrate and potassium chromate is a chemical reaction, as it involves the formation of new substances. The chemical equation for the reaction is: 2 Mg(NO3)2 + K2CrO4 -> MgCrO4 + 2 KNO3
What type of change if adding sodium chloride and silver nitrate?
chemical
Adding cream to coffee is a chemical or physical change?
It is a physical change.
Is adding water to soup A physical change or chemical change?
This is a physical process.
Is adding baking powder to scrambled eggs a physical or chemical change?
Hi
Is adding food coloring to icing a chemical or physical change?
physical change You are making a mixture of the icing and food coloring, which is a physical change.
Two colorless solutions were mixed. a yellow precipitate was formed.what possible reactants were mixed and what was the yellow coloured precipitate formed due to?
The possible reactants could be sodium thiosulfate and silver nitrate, forming a yellow precipitate of silver sulfide. Another possibility is mixing potassium chromate and lead(II) nitrate, forming a yellow precipitate of lead chromate.
Is heating cupric nitrate a physical or chemical change?
Heating cupric nitrate is a chemical change because it involves the decomposition of cupric nitrate into copper oxide, nitrogen dioxide, and oxygen. This change results in the formation of new substances with different properties from the original cupric nitrate.
Is the process of adding dish soap to water in a sink a physical or chemical change?
The process of adding dish soap to water in a sink is a physical change.
