If you add an aqueous solution of sodium sulfate (Na2SO4) to an aqueous solution of hydrochloric acid (HCl), there is NO REACTION. So, yes, it is a physical change because you made solutions of the two reagents, but for no other reason.
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.
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.
The mixing of sodium bicarbonate and hydrochloric acid is a chemical change, as it results in the formation of new substances (water, carbon dioxide, and sodium chloride) with different properties from the original reactants.
It is a chemical change because the reactants (hydrochloric acid and sodium hydroxide) are undergoing a chemical reaction to form new substances (water and salt) with different properties. The heat produced is a sign of a chemical reaction taking place.
Yes, the reaction of hydrochloric acid with sodium hydroxide is a chemical change. It forms water and sodium chloride, which are different substances with new chemical properties compared to the reactants.
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.
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.
No, mixing sodium carbonate and copper sulfate is a physical change as the substances retain their chemical identities. A chemical change would involve a reaction where new substances are formed.
It is a chemical change. An acid and a base reacting to form a new substance.
It is a chemical change because the products, H2 and HCl, are completely different from the reactants in their physical and chemical properties.
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.
The mixing of sodium bicarbonate and hydrochloric acid is a chemical change, as it results in the formation of new substances (water, carbon dioxide, and sodium chloride) with different properties from the original reactants.
It is a chemical change because the reactants (hydrochloric acid and sodium hydroxide) are undergoing a chemical reaction to form new substances (water and salt) with different properties. The heat produced is a sign of a chemical reaction taking place.
When sodium melts, it undergoes a physical change. This is because the change in state from solid to liquid does not alter the chemical composition of the sodium itself. It remains as sodium in both the solid and liquid states.
Sodium is a chemical element, not a change.
