Carbon dioxide (in solid state)
Dry ice is the solid form of Carbon Dioxide (CO2)
Dry ice is solid carbon dioxide. It has the chemical formula CO2. The correct formula for dry ice( cardice), which is solid carbon dioxide, is CO2.
Dry ice is CO2 and water is H2O; all the chemical properties are different.
Dry ice is solid carbon dioxide (CO2). It is called dry ice because it does not melt when it heats up, it goes directly from solid to gas. It is NOT the same as ordinary ice, which is of course, solid water. Dry ice is much colder than ordinary ice.
Dry ice is made of raw carbon dioxide (CO2).
Dry ice is not an element. Dry ice is solid carbon dioxide, CO2, which is a compound.
Dry ice is solidified carbon dioxide (CO2).
Dry ice doesn't "turn into smoke". Dry ice causes moisture in the air to condense, forming fog. This is a purely physical, not chemical, change.
Dry ice is simply the chemical carbon dioxide in its solid state. Dry ice is very cold and sublimates directly into carbon dioxide gas at negative 78.5 degrees Celsius at sea level.
No.
no.
Dry ice IS the solid form of carbon dioxide. And "dry ice" IS the common name for the solid CO2. So the question should be "What substance is the common name Dry Ice used for ? "
