Solid CO2 is also known as 'dry ice'
a molecular solid...
The reaction is: 2 Mg + CO2 = 2 MgO + C The black solid is this carbon.
Yes, carbon dioxide (CO2) can exist in a solid state under certain conditions, such as at very low temperatures and high pressures. This solid form of CO2 is commonly known as dry ice.
Sublimation. Transition from solid to gas, such as the "melting" of dry Ice (CO2(s) - > CO2(g))
In order for co2 to become a solid, or 'dry ice' as it's called, its temperature must be below -109.3 degrees F.
Solid CO2 is known as dry ice because it sublimes (changes from a solid to a gas) at temperatures above -78.5°C without passing through a liquid phase. This process gives the appearance of the solid CO2 "evaporating" into a gas, hence the term "dry ice".
(Explanation): If you look at the phase diagram for CO2, and you draw a lines where the temperature and pressure meet, you will see that the point will be inside the zone that is 'solid', so it is in the solid state.
Potassium hydroxide will bond with CO2 to form solid sodium carbonate and liquid water.
Carbon and carbon dioxide, CO2 are not the same. They are not even similar. Carbon is a black solid. CO2 is a colorless, odorless, gas.
State change from solid directly to gas is called sublimation, for example, dry ice - CO2(s) sublimates into gas CO2(g).
Sublimation hasn't an equation.
Dry ice is carbon dioxide CO2; CO2 is transformed directly from solid to gas.
