What else can I help you with?
Is sodium chloride physical or chemical?
This is a chemical reaction, a chemical change.
Is it a chemical or physical change if a piece of ice melts and reacts with sodium?
Melting is a physical process; reaction with sodium is a chemical process.
Is bromine with sodium a chemical or physical property?
Sodium and bromine are chemical elements, not properties; the chemical reaction between sodium and bromine is a chemical process, not a property.
Is physical or chemical reaction takes place when sodium hydroxide mixed with water?
It is a physical change. The sodium hydroxide dissolves, but it is still sodium hydroxide.
Is dissolving sodium bicarbonate in water a physical or chemical reaction?
Dissolution is considered a physical process.
Is sodium polyacrylate and water a chemical reaction?
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.
Is making salt by mixing sodium and chlorine together a physical or chemical change?
It is a physical change because the reaction can easily be reversed and no heat is involved.
Is sodium metal is insoluble in ether a chemical or physical reaction?
Sodium metal being insoluble in ether is a physical property, not a chemical reaction. This is because no new substances are being formed, it is simply a case of the sodium metal not dissolving in the ether due to differences in polarity.
Is mixing copper sulfate and sodium carbonate - chemical or physical reaction?
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.
When sodium metal in water produces hydrogen gas is it a physical property or a chemical property?
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.
Is iron chloride and sodium hydroxide a physical or chemical change?
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.
When sodium reacts violently with water is it physical or chemical property?
The reaction of sodium with water is a chemical property because it involves a chemical change where new substances are formed (sodium hydroxide and hydrogen gas) with different properties compared to the original substances (sodium and water). Physical properties, on the other hand, are characteristics of a substance that can be observed without changing its chemical composition.
