Is adding hot water to pot noodles a physical change?
Adding hot water to pot noodle is a physical change because the chemical nature of water remain unchanged.
Is adding starch in water chemical change?
Yes
Is adding water to soup A physical change or chemical change?
This is a physical process.
What kind Of Carbide is needed for lamp?
Calcium Carbide is used in "Carbide Lamps". Water, added dropwise to Calcium Carbide yields acetylene plus calcium hydroxide. Acetylene is extremely flammable, giving a colorless flame. The calcium hydroxide present gives the flame its visibility. Calcium Carbide is used in "Carbide Lamps". Water, added dropwise to Calcium Carbide yields acetylene plus calcium hydroxide. Acetylene is extremely flammable, giving a colorless flame. The calcium hydroxide present gives the flame its visibility.
How is acetylene gas prepared in the laboratory?
The usual laboratory method for making acetylene is by adding (dropwise) water to calcium carbide:CaC2 + 2 H2O → C2H2 + Ca(OH)2Calcium carbide is very cheap and available without restrictions in most countries.
How is a carbide insert manufactured?
Carbide inserts are made up of a mixture of cobalt, powdered tungsten, carbon alcohol and water which is dried to form a mixed powder. A paste is formed by adding polymer to the mixed powder. This is then pressed into insert-shaped dies and then added to a high-heat furnace which cause the carbide inserts to shrink.
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 hot water to pot noodles a physical change?
Adding hot water to pot noodle is a physical change because the chemical nature of water remain unchanged.
How do you get hydrogen from mixture of carbide and water?
The calcium carbide rips the oxygen from the water, making calcium carbonate and hydrogen. The hydrogen escapes.
Is adding starch in water chemical change?
Yes
Is adding calcium to water a chemical property or chemical change?
Calcium reacting with water is a chemical change.

Acetylene gas C2H2 is produced by adding water to calcium carbide CaC2?
Yes, acetylene gas (C2H2) is produced by the reaction of calcium carbide (CaC2) with water. The chemical reaction generates acetylene gas, calcium hydroxide, and some heat. This process is commonly used in industrial settings for welding and cutting applications.
Does adding salt to water change its pH level to become more alkaline?
No, adding salt to water does not change its pH level to become more alkaline. Salt does not directly affect the pH level of water.

Does adding salt to fresh water in and of itself change the pH of the water?
The pH is unchanged.
