Is a magnesium ribbon fizzing in acid a physical change or chemical?
The reaction of a magnesium ribbon fizzing in acid is a chemical change. This is because new substances are formed during the reaction as the magnesium reacts with the acid to produce magnesium ions and hydrogen gas.
When limestone fizzes when acid is added is physical or chemical change?
The fizzing of limestone when acid is added is a chemical change. This is because a chemical reaction occurs between the acid and the calcium carbonate in the limestone, resulting in the production of carbon dioxide gas.
Why did the fizzing stop when he countied to add the acid?
The fizzing stop when the chemical reaction is totally finished.
Is adding hydrochloric acid to magnesium ribbon a physical or chemical?
Adding hydrochloric acid to magnesium ribbon results in a chemical reaction. The magnesium reacts with the hydrochloric acid to produce magnesium chloride and hydrogen gas. This process involves the breaking and forming of chemical bonds, indicating a change in the substance's chemical identity. Thus, it is a chemical change rather than a physical one.
Is an Akkad seltzer tablet fizzing physical or chemical?
The fizzing of an Alka-Seltzer tablet is primarily a physical change. When the tablet dissolves in water, it releases carbon dioxide gas through a reaction between citric acid and sodium bicarbonate. This gas formation produces bubbles, which is the observable fizzing. However, since a chemical reaction occurs during this process, it can also be considered a chemical change.
What happens if magnesium ribbions is added in acetic acid?
When magnesium ribbon is added to acetic acid, a chemical reaction occurs which produces hydrogen gas and magnesium acetate. The magnesium ribbon will dissolve as it reacts with the acetic acid, releasing bubbles of hydrogen gas in the process. This can be observed by the fizzing or bubbling that occurs.
Is fizzing sodium bicarbonate and tartaric solution a physical or chemical change?
Fizzing sodium bicarbonate (baking soda) and tartaric acid is a chemical change. This reaction produces carbon dioxide gas, which causes the fizzing or bubbling effect. The formation of new substances, such as carbon dioxide and water, indicates a chemical transformation has occurred, rather than just a physical change where the substances would retain their original properties.
Is testing stones with acid to see if they are marble a chemical change?
No, testing stones with acid to see if they are marble is a physical change. The acid reacts with the marble to produce a fizzing or bubbling reaction, indicating the presence of calcium carbonate in the marble. This reaction does not change the fundamental chemical composition of the marble.
Is fizzing a chemical change?
Yes, fizzing is typically associated with a chemical change. It often occurs when a chemical reaction produces gas bubbles, such as in the case of an antacid tablet reacting with stomach acid to release carbon dioxide gas.
Sulphurous acid is a physical or chemical reaction?
Sulphurous acid is not a reaction (chemical or physical); the sulphurous acid (H2SO3) is a chemical compound.
How do show that adding acid to the magnesium ribbon resulted in a chemical change?
Adding acid to magnesium ribbon results in a chemical change because it produces hydrogen gas and magnesium ions through a reaction. This change can be observed by the formation of bubbles (hydrogen gas) and the dissolution of the magnesium ribbon. Unlike physical changes, the original substances (magnesium and acid) are transformed into new products with different chemical properties. The reaction can be represented by the equation: Mg + 2HCl → MgCl₂ + H₂.
Is a react with acid a chemical or a physical property?
Chemical property because acid is a chemical
