Insoluble
Melting is a physical process; reaction with sodium is a chemical process.
It is a physical change. The sodium hydroxide dissolves, but it is still sodium hydroxide.
No, mixing sodium polyacrylate with water is a physical interaction rather than a chemical reaction. The sodium polyacrylate absorbs the water, forming a gel-like substance, but no new chemical bonds are formed.
A chemical reaction will occur, resulting in the formation of insoluble calcium phosphate (a white solid) and sodium nitrate dissolved in the solution. This reaction is a double displacement reaction where the ions switch partners.
The reaction between iron (III) chloride and sodium hydroxide is a chemical change as new substances are formed. Iron (III) hydroxide and sodium chloride are produced as a result of the reaction.
For example the product of the reaction between sodium chloride and silver nitrate is the insoluble silver chloride.
This is a chemical reaction, a chemical change.
Melting is a physical process; reaction with sodium is a chemical process.
Sodium and bromine are chemical elements, not properties; the chemical reaction between sodium and bromine is a chemical process, not a property.
It is a physical change. The sodium hydroxide dissolves, but it is still sodium hydroxide.
Dissolution is considered a physical process.
Sodium sulfate is soluble in water. Hydrochloric acid is a water solution of HCl. Solubility is considered a physical property.
No, mixing sodium polyacrylate with water is a physical interaction rather than a chemical reaction. The sodium polyacrylate absorbs the water, forming a gel-like substance, but no new chemical bonds are formed.
It is a physical change because the reaction can easily be reversed and no heat is involved.
Mixing copper sulfate and sodium carbonate would be considered a chemical reaction because a new substance is formed as a result of the reaction between the two compounds, resulting in the formation of copper carbonate and sodium sulfate.
The reaction of sodium metal with water to produce hydrogen gas is a chemical property. This is because a new substance (hydrogen gas) is formed as a result of a chemical reaction between sodium and water.
A chemical reaction will occur, resulting in the formation of insoluble calcium phosphate (a white solid) and sodium nitrate dissolved in the solution. This reaction is a double displacement reaction where the ions switch partners.
