Is adding copper with gold to make jewelry a chemical change?
No, adding copper to gold to create jewelry is not a chemical change; it is a physical change. This process involves alloying, where metals are mixed to form a new material with different properties, but the original metals retain their chemical identities. The resulting alloy, such as rose gold or white gold, can be reshaped and manipulated, but no new substances are formed during this process.
What is any chemical substance formed as the result of a chemical reaction?
A chemical substance formed as a result of a chemical reaction is called a product. Products can be either the desired end product of the reaction or byproducts that are formed during the reaction.

Which gas is formed when you mix sugar and coke?
When you mix sugar and Coke, the primary gas that is formed is carbon dioxide (CO2). This gas is already present in Coke due to carbonation, but adding sugar can cause the release of more CO2 from the solution, leading to fizzing or bubbling. The reaction is not a chemical one but rather a physical reaction where the sugar interacts with the carbonated beverage, potentially increasing the effervescence.
Is adding phenolphthalein to sodium hydroxide a chemical change?

Is adding HCl to Mg a physical or chemical change?
Adding HCl to Mg would result in a chemical change. The reaction between hydrochloric acid (HCl) and magnesium (Mg) produces hydrogen gas (H2) and magnesium chloride (MgCl2), which are new substances formed by a rearrangement of atoms. This is a chemical change because the composition of the substances involved is altered.
