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 the purpose of using dry test tube for gringard reaction?
Using a dry test tube for a Grignard reaction is important to prevent any unwanted reactions or side reactions from occurring due to the presence of water or other impurities. Grignard reagents are extremely sensitive to moisture and can react with water to form magnesium hydroxide, which can interfere with the desired reaction. It is essential to keep the test tube dry to ensure the success of the Grignard reaction.
Is evaporation of dry ice a decomposition reaction?
No, the evaporation of dry ice is a physical change, not a decomposition reaction. Dry ice is solid carbon dioxide, and when it evaporates, it changes directly from a solid to a gas without undergoing a chemical reaction.
Why important to use dry solvent in the formation of the sulfonamide?
Using a dry solvent is important in the formation of sulfonamides because water can hydrolyze the sulfonamide intermediate, leading to side reactions or lower yields. Keeping the reaction conditions anhydrous ensures the success of the sulfonamide formation reaction.
Is mixing cement with water and letting it dry a physical change?
No, mixing cement with water and letting it dry is not a physical change; it is a chemical change. When water is added to cement, a chemical reaction occurs, leading to the hardening and setting of the mixture as it forms new compounds. This process is irreversible, distinguishing it from physical changes, which do not alter the chemical composition of the substances involved.
What is the wet carbonization and dry cabnization?
Wet carbonization is a process where organic materials are carbonized in the presence of water, which helps to lower the temperature needed for the reaction. Dry carbonization, on the other hand, involves carbonizing organic materials in the absence of water. Both processes produce char or charcoal, but wet carbonization may result in a higher yield due to the presence of water.
How can instantaneous smoke be produced by a reaction?

Can you dry pour concrete without adding water?
No, you cannot dry pour concrete without adding water. Water is necessary to activate the chemical reaction that causes the concrete to harden and set properly.
Why does water react differently to dry ice then soda?
Water is uncompressed therefore the reaction isn't as big as soda with all the chemical contained.
Why does the reaction for the preparation of tin IV iodide need to be performed under dry conditions?
The reaction for the preparation of tin IV iodide needs to be performed under dry conditions to prevent the reactants from reacting with water or moisture in the air. Water can hydrolyze the tin IV iodide, reducing the yield of the desired product and interfering with the reaction. Dry conditions ensure that the reaction proceeds smoothly and the product is obtained in high purity.
How the amount of water affects the germination?
The enzymes in the dry seeds get activated after absorbing water and it unlocks several chemical reaction leading to the germination of seed.
What happens during the dry ice in water reaction?
When dry ice, which is solid carbon dioxide, is placed in water, it sublimates, meaning it turns directly from a solid to a gas. This creates a foggy effect as the carbon dioxide gas mixes with the water vapor in the air.
What will happen when dry slaked lime react with chlorine?
When dry slaked lime reacts with chlorine gas, it forms calcium chloride, calcium hypochlorite, and water. This reaction is commonly used in water treatment processes to disinfect and purify water, as calcium hypochlorite is a powerful disinfectant.
Can P4O10 be used to dry ammonia?
instead of drying ammonia,P4o10 reacts with it thereby disrupting the process.
What kind of womens shirt can I wear to keep me dry when it is wet outside?
You can always get a runner's shirt made of water-repellent materials to keep you dry.
When you breathe on a window and your air condenses on the window is the liquid that was condensed saliva or water?
basically its water because it has the nearest chemical reaction to it but saliva is the nearest chemical reaction to blood but if you bleed on something and wait for it to dry it condenses more into saliva
