Is Hydration a physical or chemical change?
Hydration is a chemical reaction. It involves the addition of water to another substance.
C0cl2 and water is it a physical or chemical change?
When CCl2 is added to water, it undergoes a physical change because the molecular structure of both substances remains the same. The CCl2 molecules simply disperse throughout the water, forming a homogeneous solution, without any new chemical bonds being formed or broken.
Is hollow block a physical change?
No, hollow block is not a physical change. A physical change refers to changes in the state or appearance of a substance without altering its chemical composition. However, hollow block is a building material made from a mixture of cement, sand, and other aggregates, which undergoes a chemical change (hydration) during the curing process.
What reaction receives water?
The reaction that receives water is called a hydration reaction. In this process, water molecules are added to a substance, typically causing a chemical change. One common example is the hydration of an alkene, where water adds across the double bond in the presence of an acid catalyst, leading to the formation of an alcohol. Additionally, hydration is also crucial in biochemical processes, such as the hydration of glucose during cellular metabolism.
What is the difference between physical and chemical weathering change?
Physical weathering involves the breakdown of rocks into smaller pieces without changing their chemical composition, such as through freeze-thaw cycles or abrasion. Chemical weathering, on the other hand, alters the chemical composition of rocks through processes like oxidation or hydration, leading to the formation of new minerals.
Is Hydration a physical or chemical change?
Hydration is a chemical reaction. It involves the addition of water to another substance.
When water and concrete mix are combined the material becomes warm and a hard solid forms. is this a physical change or a chemical change?
This is a chemical process: a hydration reaction occur.
What chemical weathering process occurs when chemicals in a rock combine with water to form a new substance?
This chemical process is called hydration.
Which chemical weathering process occurs when chemicals combine with water in a chemical reaction to change the physical of the rock?
Hydration is the chemical weathering process that occurs when minerals in the rock react with water to form new minerals or alter the structure of the rock. This process helps break down rock into smaller particles over time.
When water and concrete mix are combined the material becomes warm and a hard solid forms so Is this a physical change or a chemical change?
The reaction between water and concrete is a chemical change because new substances are formed as a result of the mixing process. In this case, the components of the concrete react with the water to form a new compound that hardens into a solid material through a chemical reaction.

Is the setting of concrete a physical or chemical change?
It's a physical change.It's a chemical change. The concrete hardens through a chemical reaction called hydration :)Its a physical change. The Chemical change already happened when the water was added. The concrete powder became hydrated turning it into usable concrete.
