What physical change is skipped during the decomposition of dry ice?
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.
Does a decomposition reaction decompose to a limiting reactant and a theoretical reactant?
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.
What is solid CO2 called?
a molecular solid...
What is the chemical name of dry ice. why is it called dry ice. Is dry ice is same as the ordinary ice?
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.
What happens if you put saltbon dry ice?
You will have some dry water sodium. Salty dry ice.
Why is dry ice evaporation a physical chainge?
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.

Will salty water still be salty after dry ice has evaporated?
1. The term evaporation is not adequate for dry ice (solid carbon dioxide); the correct term is sublimation.2. Water remain salty.
How does ice disappear in the freezer?
Ice can disappear over a period time in a freezer due to evaporation. Most freezers have a very dry environment with low humidity.
What happens to temperatures in an endothermic reaction and examples?
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.
What form of matter is the ice in Antarctica that goes directly into the atmosphere?
Because Antarctica is so dry, you may be thinking of evaporation. In this process, ice becomes hydrogen and oxygen.
Does dry ice react to vinegar?
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).
Does a decomposition reaction decompose to a limiting reactant and a theoretical reactant?

Is dry ice mixed with vinegar dangerous?
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.
How will dry ice react to baking soda?
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.
Which of the following is endothermic a dry ice evaporating b a sparkler burning c the reaction that occurs in a chemical cold pack often used to ice athletic injuries?
Dry ice evaporating is endothermic-->+DeltaH A sparkler burning is exothermic--->-DeltaH The reaction that occurs in a chemical cold pack often used to ice athletic injuries is endothermic--->+DeltaH
