If a person took dry ice into his mouth, he would kill all the tissue that the dry ice touched, and could possibly die.
If you even touch dry ice, it is so cold that it feels like it is burning you. Imagine what it could do to the thin, sensitive tissues in your mouth and throat.
It depends what the dry ice is mixed with what happens. If mixed with soap it will create a foamy bubbly mess and when mixed with water it creates fog.
the dry ice melts rapidly producing the gas form of what ever it happened to be
Other than (potentially) a huge explosion due to the massive evolution of gas, nothing will happen as you cannot burn dry ice - it is solid carbon dioxide.
the ice will melt ..... i think
No, dry ice will not melt on contact with salt. In the first place, dry ice does not melt. It does not have a liquid phase under normal atmospheric pressure. It transforms from solid to gas, which is called sublimation. Dry ice sublimes, rather than melts. Secondly, salt has no effect on the sublimation of dry ice. Salt has an effect on frozen water, but it does not have an effect on frozen carbon dioxide. Salt is soluble in water, it is not soluble in carbon dioxide.
What are you asking here? Dry ice sublimes into gaseous CO2, whereas salt is easily held by the water molecules in solution.
Dry Ice because dry ice is frozen carbon dioxide, totally different from ordinary ice, which is frozen water. Dry ice is much colder than water ice, thus it melts faster. P.S. DO NOT TOUCH IT FREEZES YOUR SKIN INSTANTLY!!
Temperature causes changes in dry and water ice
When you put cinnamon it dry ice it adbrutly melts.
Yes, you can put dry ice in salt water. It will bubble furiously and cool down the salt water.
You will have some dry water sodium. Salty dry ice.

I assume you are asking why salt melts ice. It's very difficult to tell from your question... What happens, is that ice always has a thin layer of liquid water on it. When salt disolves in water it produces heat, melting the ice, providing more liquid water to disolve the salt into.
The temperature decrease and water can be transformed in ice.
it foams
Rather than melts, dry ice evaporates. This process is called sublimation and happens at a slower rate than the melting of water ice.
nothing, it's only effective when salt is sprinkled ON the ice.
Pouring the salt in your hand and squeezing the ice cube for at least 5 to 10 minutes will leave a huge blister.

It melts slowly.
it is a process called freezing point depression. The salt lowers the freezing point of water therefore it has to be colder for the water to return to ice
