What chemical properties do dry ice and water ice have different?
Dry ice is CO2 and water is H2O; all the chemical properties are different.
Is combining dry ingredients a physical or chemical change?
Combining dry ingredients is a physical change. In this process, the individual components retain their chemical identities and properties, and no new substances are formed. The change is primarily in the mixture's physical state and appearance, but the original substances remain unchanged at the molecular level.
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 are two physical properties for graham cracker?
Two physical properties of graham crackers are their texture and color. Graham crackers typically have a crisp, crunchy texture that results from being baked until dry. They are usually a light brown color, which comes from the whole wheat flour and the Maillard reaction during baking. These properties contribute to their distinctive appearance and mouthfeel.
Why is the insulating properties of neoprene is not needed on a drysuit?
Neoprene is not typically used in drysuits for its insulating properties because drysuits are designed to keep the wearer dry, not warm. Neoprene wetsuits are used for insulation in cold water because they trap a thin layer of water against the skin that warms up to provide insulation. Drysuits use breathable waterproof materials to keep the wearer dry without the need for insulating properties.
What chemical properties do dry ice and water ice have different?
Dry ice is CO2 and water is H2O; all the chemical properties are different.
What are the physical properties of wood?
Some physical properties of wood (mainly cellulose) are that it can be strong and dense. Dry wood is an electrical insulator, because of the lack of water, and the many air spaces. When wet, wood is susceptible to mold and bacterial decomposition.

What are the physical properties of juice?
water soluble dry matter, vitamin C, pH, titratable acidity, reducing sugar, sucrose and some minerals
Do the dry and wet iron filings show the same physical properties?
Dry iron filings and wet iron filings have different physical properties. Dry iron filings are free-flowing and easily spread out, while wet iron filings clump together due to the presence of water. Additionally, wet iron filings may rust more easily due to the moisture content.
What are the common methods for managing sump discharge in residential properties?
Common methods for managing sump discharge in residential properties include directing the water to a storm sewer, using a dry well or infiltration trench, or utilizing a sump pump to remove the water to a safe location away from the property.
Is a physical change A. an iron bar rusting B. oil floating on water C. a copper skillet tarnishing D. the sublimation of dry ice?
The answer is D; the sublimation of dry ice. A physical change alters one of the physical properties of a substance (e.g. size, shape, color, etc.), but it does not change the substance itself. A chemical change causes new substances to be formed. The new substances have different chemical properties from the original substance. Changes in the state or phase of matter, such as the sublimation of dry ice (solid carbon dioxide), are physical changes because the chemical compositions of the substances do not change. Sublimation is the change of an object from a solid-state directly to a gaseous state.

What is the most common gas found in dry air in the troposphere?
the most common gas is water vapor
Is squeezing oranges to make orange juice is a physical property?
water soluble dry matter, vitamin C, pH, titratable acidity, reducing sugar, sucrose and some minerals
How common is experiencing a dry cough after drinking cold water?
Experiencing a dry cough after drinking cold water is not very common, but it can happen to some people who are sensitive to temperature changes or have underlying respiratory issues.
What is common animal adaptation to prolonged dry weather?
Common animal adaptions to prolonged dry weather are great in number. Common animal adaptions include water conservation in limbs and stomachs.
