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 kind of reaction is dry ice and water exploading?
The reaction between dry ice (solid carbon dioxide) and water is a physical reaction rather than a chemical one. When dry ice is added to water, it sublimates rapidly, turning from solid to gas, which creates a large volume of carbon dioxide gas and can lead to an explosive release of gas if contained. This reaction can create a dramatic visual effect, often seen in science demonstrations, but it is important to handle it cautiously due to the potential for pressure build-up.
What is solid CO2 called?

What happens when you place an iceblock in a dry tumbler?
When you place an ice block in a dry tumbler, the ice begins to melt as it absorbs heat from the surrounding air and the tumbler itself. As the ice melts, it turns into water, which remains in the tumbler. Since there is no additional moisture in the dry tumbler, the water will accumulate at the bottom without any immediate evaporation. Over time, if the environment allows, the melting ice will cool the air inside the tumbler, causing condensation on the outer surface if the temperature is right.
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).

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
