What is the chemical residue left in the charring test?
the charring test would result a Gay person, or also known as Homosexual, the chemical residue that the "charring" test proves to be very effective in metamorphing a male human, into a gay or homosexual person.
Which fiber burns completely without leaving any residue?
Acrylic fiber burns completely without leaving any residue.
What is the chemical name for white ash?
The chemical name for white ash is calcium oxide (CaO). It is a common compound formed when calcium carbonate (CaCO3) is burned at high temperatures, leaving behind the white ash residue.
What is the difference between a carbonate residue and an impression?
A carbonate residue is a chemical deposit left behind by the reaction of a carbonate compound with an acid, resulting in the release of carbon dioxide gas. On the other hand, an impression refers to a negative imprint or mark left behind on a surface due to pressure or contact with an object. While carbonate residues are formed through a chemical process, impressions are physical marks created by pressure or contact.
Is a methanol is burned and leaves a residue a chemical change?
Burning (an oxidation reaction) is a chemical change,
Is copper and silver a chemical or physical change?
It is a chemical change because it leaves a residue (which is a sign of chemical change) Hope that helps
When methanol is burned and leaves a residue a physical or chemical change?
When methanol burns and leaves a residue, it undergoes a chemical change. The burning of methanol involves a combustion reaction, where the methanol is reacting with oxygen to form new substances, such as carbon dioxide and water. The residue left behind is a result of this chemical reaction.
If dish of sugar and water solution is left in the sun after a few days the solution has disappeared and a white residue remains on the dish Has a physical or chemical change taken place explain?
Yes, A physical change has taken place. The water has evaporated and left the sugar. Neither substance has changed its identity. GOOD LUCK ON YOUR TEST!

Is powdery a physical or chemical change?
Powdery is an adjective which not require any change!You can have a physical change where a large lump of some substance is ground into powder. Or you can have a chemical change (eg magnesium burning) which leaves a powdery residue.

Why camphor disappears without leaving any residue?
Camphor disappears without leaving any residue because it undergoes sublimation, a process where a solid transitions directly into a gas without passing through a liquid state. This means that camphor molecules turn into vapor and escape into the air, leaving no solid residue behind.
How can I prevent water from leaving white residue on surfaces?
To prevent water from leaving white residue on surfaces, you can use distilled water or a mixture of vinegar and water for cleaning. Additionally, wiping surfaces dry after they come into contact with water can help prevent the buildup of white residue.
What kind of residue does acetone leave behind?
Acetone typically evaporates completely, leaving behind little to no residue. If any residue is left behind, it would likely be a small amount of solid impurities or contaminants that were dissolved in the acetone.

What are the ways that burning changes the nature of wood?
Burning causes a physical and chemical change to wood. The physical change comes from the cellulose in the cell walls undergoing incomplete combustion and leaving behind ash and charred residue. The chemical changes that occur happen when the organics undergo complete combustion and turn into carbon dioxide and water vapor.
