Yes, it is a new, liquid-liquid solution.
There is no specific name for 'something which reacts with vinegar'. Vinegar is ethanoic acid and reacts with various substance. Some examples are alkalis like sodium hydroxide, metal carbonates and alcohols such as ethanol.
If they're mixed, but remain separate (as in a solution) then the answer is no. But if the two chemicals undergo a chemical reaction with each other then at least one new substance will be formed; if there are by-products from the reaction, then more than one new substance will be produced.
Yes, there is, it is a solution of coffee powder in water.
When you put chalk in vinegar the chalk is dissolved and broken down. However, as a result of the mixture of compounds co2 is formed.
There is no new substance; it is just mixed up and all the atoms are spread out so you can't see the individual particles.
It is a mixture. It is a liquid-liquid solution.
When baking soda and vinegar are mixed,a chemical reaction occurs.A new substance is made.The new substance is carbon dioxide.
When eggshells are mixed with vinegar, a chemical reaction occurs between the calcium carbonate in the eggshells and the acetic acid in the vinegar. This reaction results in the formation of calcium acetate, water, and carbon dioxide. So, new material is formed, called Calcium acetate, but eggshells physically mixed with vinegar, don't form any new material
The difference between chemical and physical changes is that chemical change is when a new substance is formed, and the reaction is irreversible. So as salt and vinegar do not react, it is indeed a physical change.

The product of this chemical reaction is casein, a protein.
If they're mixed, but remain separate (as in a solution) then the answer is no. But if the two chemicals undergo a chemical reaction with each other then at least one new substance will be formed; if there are by-products from the reaction, then more than one new substance will be produced.
Yes, it is a coffee flavoured solution.
Yes, there is, it is a solution of coffee powder in water.
When you put chalk in vinegar the chalk is dissolved and broken down. However, as a result of the mixture of compounds co2 is formed.
"New substances" is a vague description of what happens in a chemical reaction. Simply put though, yes. An example of this would be if you took baking powder and vinegar and mixed them together, the resulting chemical reaction would create Carbon Dioxide. That is a new substance, it wasn't there until the reaction took place.
There is no new substance; it is just mixed up and all the atoms are spread out so you can't see the individual particles.
