Copper sulfate and sodium carbonate physical or chemical change?
When copper sulfate and sodium carbonate are mixed together, a chemical reaction occurs. This reaction forms copper carbonate, a new substance with different properties than the reactants. Therefore, the mixing of copper sulfate and sodium carbonate is a chemical change.
Is heating copper carbonate a chemical change?
Yes, heating copper carbonate is a chemical change because it undergoes thermal decomposition to form new substances, copper oxide and carbon dioxide. This is a chemical reaction that results in the formation of different compounds with distinct properties.
Is copper sulphate a physical change or chemical?
Copper sulfate dissolving in water is a physical change as no new substance is formed. However, if copper sulfate is heated to decomposition, it would be a chemical change because a new substance is formed.
By heating green copper carbonate so that it changes to black copper oxide will this be a chamical or physical change?
The change from green copper carbonate to black copper oxide is a chemical change because it involves a chemical reaction where the chemical composition of the substance is altered. The color change indicates a new substance has formed, making it a chemical change.
Three things that you observe in a chemical change of mixture Mg-CuSO4?
Formation of a new substance: When magnesium reacts with copper sulfate, the blue color of copper sulfate fades as copper metal is formed, indicating a chemical change has occurred. Release of gas: In this reaction, bubbles of gas may be observed, which could be hydrogen gas being evolved as magnesium displaces copper from copper sulfate. Temperature change: The reaction between magnesium and copper sulfate is exothermic, meaning it releases heat. The mixture may feel warm or hot to touch during the reaction, indicating a temperature change has taken place.
Copper sulfate and sodium carbonate physical or chemical change?
When copper sulfate and sodium carbonate are mixed together, a chemical reaction occurs. This reaction forms copper carbonate, a new substance with different properties than the reactants. Therefore, the mixing of copper sulfate and sodium carbonate is a chemical change.
Why sodium carbonate is not a chemical change?
Sodium carbonate is a compound. Until you react it with something, it cant have or be a chemical change.
Is dissolving sodium carbonate a chemical change?
Dissolving sodium carbonate in water is a physical change, not a chemical change. This is because the chemical composition of sodium carbonate remains the same before and after dissolving.
Is magnesium sulfate in water a physical or chemical change?
When magnesium sulfate dissolves in water, it undergoes a physical change, not a chemical change. The molecules of magnesium sulfate are simply dispersed in the water, but no new chemical substances are formed.
Why is heating cupric sulfate a chemical change?
It is not.
Is adding water to heated copper sulfate crystals chemical or physical?
Adding water to heated copper sulfate crystals is a chemical change. When water is added to heated copper sulfate crystals, the copper sulfate undergoes a chemical reaction where it dissolves in the water to form a solution. This is a chemical change because the chemical composition of the copper sulfate is altered during the process.
Is crushing of sodium carbonate chemical change?
No, crushing sodium carbonate does not produce a new chemical substance. Thus, crushing is an example of a physical change.
Is macaroni a chemical change or mixture?
Macaroni is a mixture not a change.
Is heating copper carbonate a chemical change?
Yes, heating copper carbonate is a chemical change because it undergoes thermal decomposition to form new substances, copper oxide and carbon dioxide. This is a chemical reaction that results in the formation of different compounds with distinct properties.
Is copper sulphate a physical change or chemical?
Copper sulfate dissolving in water is a physical change as no new substance is formed. However, if copper sulfate is heated to decomposition, it would be a chemical change because a new substance is formed.
When copper sulfate mixed with sodium hydroxide is a form of physical change or chemical change?
The reaction between copper sulfate and sodium hydroxide is a chemical change, as new substances are formed with different chemical properties from the original substances. The blue copper sulfate solution reacts with the colorless sodium hydroxide solution to form a blue precipitate of copper hydroxide and sodium sulfate solution.
Is adding calcium chloride to sodium carbonate a physical change or a chemical change?
Adding calcium chloride to sodium carbonate would be a chemical change because it results in the formation of new substances (calcium carbonate and sodium chloride) with different chemical properties than the original reactants.
