Dry ice, the solid form of carbon dioxide, doesn't melt (turn into a liquid) under ordinary circumstances. It changes state directly from a solid into a gas. We term this change sublimation, and dry ice is said to sublime.
A decomposition reaction breaks down a compound into simpler substances. It does not involve limiting reactants or theoretical reactants, as these concepts are typically associated with reactions that involve multiple reactants forming products.

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.
You will have some dry water sodium. Salty dry ice.
Dry ice is a solid form of cooled carbon dioxide. When it reaches room temperature it changes to gaseous carbon dioxide. Since, there is no change in the chemical composition of dry ice, it is called a physical change.

1. The term evaporation is not adequate for dry ice (solid carbon dioxide); the correct term is sublimation.2. Water remain salty.
Ice can disappear over a period time in a freezer due to evaporation. Most freezers have a very dry environment with low humidity.
In an endothermic reaction, temperatures decrease because heat is absorbed from the surroundings to drive the reaction. Examples include photosynthesis, the evaporation of water, and the melting of ice.
Because Antarctica is so dry, you may be thinking of evaporation. In this process, ice becomes hydrogen and oxygen.
Dry ice, which is solid carbon dioxide, does react with vinegar. When dry ice is added to vinegar, it sublimates (changes directly from a solid to a gas) and produces carbon dioxide gas. This reaction creates bubbles and fizzing as the carbon dioxide gas is released. The overall reaction is: CO2 (dry ice) + 2CH3COOH (vinegar) -> 2CH3COO- (acetate ion) + 2H2O (water) + CO2 (carbon dioxide gas).

Mixing dry ice with vinegar can create a reaction that produces carbon dioxide gas, which is not harmful in small quantities. However, if done in an enclosed space, it can potentially displace oxygen and create a suffocation risk. It is important to use caution and ensure proper ventilation when working with dry ice and vinegar.
Dry ice and baking soda can react exothermically, causing the dry ice to sublimate (turn into gas) rapidly. This reaction can create a fog-like effect due to the rapid release of carbon dioxide gas. It is important to handle dry ice with caution and in a well-ventilated area when conducting experiments with baking soda.
