What else can I help you with?
If liquid that's green from sweet is heated on a radiator it makes a green solid what has happened to the water?
The water has evaporated and left behind the solid residue of the sweet material, resulting in the green solid. This process is called evaporation and leaves the solid substance behind as the water in the liquid evaporates.
What yellow solid heated in no air turns black?
Sulfur is a yellow solid that, when heated in the absence of air, sublimes into a black solid as it undergoes a phase change from solid to gas.
What is a solid purple-black non metal which changes to a deep purple gas when heated?
Iodine is a purple-black non metal that changes to a deep purple gas when heated.
The solid residue that remains when a hydrate is heated is?
The solid residue that remains when a hydrate is heated is the anhydrous compound, which is the compound without any water molecules. Heating a hydrate removes the water molecules through the process of dehydration, leaving behind the anhydrous form of the compound.
What is the black solid left by sugar?
The black solid left by sugar when it is burned or heated to high temperatures is primarily carbon, along with some other compounds resulting from the decomposition of sugar. This process, known as caramelization, can lead to the formation of charred remnants that are very dark due to the breakdown of the sugar's molecular structure. This black residue is often referred to as carbonized sugar or charred sugar.

What is left behind when a solution is heated?
A solid insoluble residue remain after the evaporation of water.
What yellow solid heated in no air turns black?
Sulfur is a yellow solid that, when heated in the absence of air, sublimes into a black solid as it undergoes a phase change from solid to gas.
What is the residue left after charring a sucrose?
What is left after heating sucrose is charcoal or solid carbon (C2). Heating causes sucrose to decompose as referred to this chemical reaction: C12H22O11 + O2 (the air is filled with it) - Heated --> CO2 + H2O + C2
When a green solid substance was heated up it broke down into a black solid and a colourless gasis it a mixture or compound?
The gas and the solid are two different compounds, they won't be the same therefore they'd be a mixture.
What is a blue solid that produces a black solid when heated?
Either sodium carbonate or copper carbonate
What white powder when heated produces a colourless gas and a black solid?
When heated, zinc oxide (white powder) decomposes into zinc vapor (colorless gas) and solid zinc suboxide (black solid).
If a light green powder is heated in a test tube A gas is given off while the solid becomes black In which classification of matter does the green powder belong?
The green powder belongs to the category of chemical substances. This is because it undergoes a chemical change when heated, giving off a gas and forming a black solid, indicating a chemical reaction has occurred.
What black solid forms a purple vapour when heated gently?
Iodine is a black solid that sublimes directly to a purple vapor without passing through a liquid phase when heated gently.
What happen in the evaporating dish as water in thr beaker is being heated?
After the total evaporation of water a small solid residue can remain in the beaker.
What is a solid purple-black non metal which changes to a deep purple gas when heated?
Iodine is a purple-black non metal that changes to a deep purple gas when heated.
