Which apparatus is used for the cooling of precipitate of ignited residue?
Answers
Answer:
Physical Properties:
Non-metals are not ductile so, they cannot be made into thin wires. Non-metals are insulators or poor conductors of electricity and heat because they do not lose electrons to transmit the energy. At room temperature, they can be in the state of solids, liquids or gases. They are non-sonorous.
Explanation:
Metal Physical Properties:
Lustrous (shiny)
Good conductors of heat and electricity.
High melting point.
High density (heavy for their size)
Malleable (can be hammered)
Ductile (can be drawn into wires)
Usually solid at room temperature (an exception is mercury)
Opaque as a thin sheet (can't see through metals)
Answer:
Post-precipitation. It is the precipitation that occurs as a layer upon the already formed precipitate. It is a surface based contamination/impurity that occurs due to high primary adsorption and supersaturated solution.
