Removing tarnish from a penny with salt and vinegar is a chemical change. The reaction between the salt, vinegar, and tarnish on the penny results in the formation of new substances that remove the tarnish.
The addition of sugar to vinegar is a physical change because no new substances are formed. Sugar dissolves in the vinegar, but the chemical composition of both sugar and vinegar remains the same.
One way to tarnish a penny is by exposing it to a mixture of salt and vinegar. This combination creates a chemical reaction that causes the copper surface of the penny to darken and tarnish over time.
Yes, the combination of salt and vinegar on the copper pot creates a chemical reaction that helps remove tarnish and dirt from the surface. The salt acts as an abrasive while the vinegar reacts with the tarnish to help dissolve it, making it easier to clean the pot.
When vinegar and salt are combined to clean pennies, a chemical reaction occurs that removes the tarnish on the coins. The acidic vinegar breaks down the tarnish while the salt acts as a mild abrasive to help scrub away the debris. This process can restore the shine and luster of the pennies.
Vinegar having a pungent odor is a physical property, as it is related to our perception of its scent. Chemical properties, on the other hand, relate to how a substance interacts with other substances on a molecular level.
Physical change
Cleaning a penny with vinegar and salt is a chemical change. The vinegar (acetic acid) reacts with the salt (sodium chloride) to form a chemical compound that removes the tarnish on the copper surface of the penny. This reaction changes the composition of the penny's surface, making it appear shiny and clean.
Yes ,Vinegar and any other element of the Periodic Table have a chemical and physical property.
physical- there's no chemical change.
The addition of sugar to vinegar is a physical change because no new substances are formed. Sugar dissolves in the vinegar, but the chemical composition of both sugar and vinegar remains the same.

Yes, reactivity to vinegar is an example of a physical property because it describes how a substance behaves without altering its chemical composition. In this case, the reaction between vinegar and a substance demonstrates a physical change rather than a chemical one.
Reactivity is a chemical property (in chemistry !).
