yes it as it forms a new substance
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.
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.
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.
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.
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.
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.
Sodium carbonate is a compound. Until you react it with something, it cant have or be 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.
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.
It is not.
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.
No, crushing sodium carbonate does not produce a new chemical substance. Thus, crushing is an example of a physical change.
Macaroni is a mixture not a 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.
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.
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.
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.
