2 ways i know of checking gold is no.1 scrape it somehow and if the color is consistent it should be real , that's how scrappers do it , proffesionals use acid.the pour it on the gold and if it doesn't turn a different color its real.
The density, or mass of an object divided by volume, differs for all objects. Fools gold, or otherwise known as pyrite, looks like gold, but the density is 4.8-5 grams/cm^3. Real gole is 19.32
The acid test is used to determine the presence of carbonate minerals in a sample. If the mineral fizzes or reacts with acid, it indicates the presence of carbonate minerals such as calcite or dolomite.
One way to prove that 'ash' is acidic is to test its pH using a pH indicator strip or pH meter. If the pH is below 7, it indicates acidity. Additionally, you could perform a litmus paper test, where the ash would turn red if it is acidic.

Carbon monoxide is a neutral gas and is neither acidic nor alkaline. Its pH is around 7. To prove this, you could test the substance with litmus paper; if it does not change color, it indicates that it is neutral.
You cannot prove it because it is not true.The expected value of the sample variance is the population variance but that is not the same as the two measures being the same.
Yes. No problem.
One ring to rule them all... one ring to bind them...
The marketing section could tell past and future ways to sell a product. It would contain a lot of research to prove the points.
This question makes no sense. If people could prove whether or not aliens exist, then conspiracy theories would be a thing of the past. Again, this question makes no sense.
Once because he were drunk. To prove to the police that he really was Eric, he asked them to give him a guitar. Then he could get out.
not only to prove a hypothesis, but disprove it as well
The prospective voter had to prove he could read and write.

No one really knows . As for the song breakeven the lyrics " Just praying to a God, that I don't believe in " could prove something .
Look at the family tree of yours and demi lovato's. Gene testing (take demi lovato's sample and your sample) whatever contains DNA or mitochondria.
