The solid residue that remains when a hydrate is heated is?
The anhydrous molecule or species. e.g. CuSO4.5H2O (hydrate) + heat ----> CuSO4 (anhydrous) + water vapor
If liquid that's green from sweet is heated on a radiator it makes a green solid what has happened to the water?
I would assume that the water evaporates.
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.
When crystals of feso4 are strongly heated the residue obtained is?
The residue obtained from heating crystals of FeSO4 (iron(II) sulfate) is Fe2O3 (iron(III) oxide) and SO2 (sulfur dioxide) gases. This is because the heating process causes the iron(II) sulfate to decompose, releasing water vapor, sulfur dioxide gas, and leaving iron(III) oxide as a solid residue.
Contrast the changes in a crystalline solid as it is heated to those in an amorphous solid that is heated?
crystalline gets hotter then amorphous
What is the definition of carbon residue?
Carbon residue is deposits of solid black residue from burnt carbon.
What is left behind when a solution is heated?
A solid insoluble residue remain after the evaporation of water.
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 solid residue?
Solid residue is what remains after a liquid evaporates.
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
What is a blue solid that produces a black solid when heated?
Either sodium carbonate or copper carbonate
The solid residue that remains when a hydrate is heated is?
The anhydrous molecule or species. e.g. CuSO4.5H2O (hydrate) + heat ----> CuSO4 (anhydrous) + water vapor
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 black solid forms a purple vapour when heated gently?
>
What is the nature of a solid when it is heated it melts at a definite temperature and further heating produces black solid and a gas?
carbon
If liquid that's green from sweet is heated on a radiator it makes a green solid what has happened to the water?
I would assume that the water evaporates.
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 is copper (2) carbonate. When heated it decomposes to give copper (2) oxide (which is black) and carbon dioxide . It is a compound.
