Gold and copper can vary in size depending on the context in which they are measured. However, if you're referring to their density and atomic structure, gold is denser and heavier than copper, meaning that for the same volume, gold will weigh more. In terms of elemental abundance in the Earth's crust, copper is more prevalent than gold. Thus, while gold is not "bigger" in a physical sense, it is more dense than copper.
Yes, 25 is bigger than 13.
0.6 is bigger than 0.3
No. 3.141 is 3.14 + 0.001, so 3.141 is bigger than 3.14
Three ninths is one third, and eighths are bigger than ninths. Three eighths is bigger than three ninths. Therefore three eighths is bigger than one third.
It is bigger
No, gold will not replace copper from a copper sulfate solution through a displacement reaction. Gold is less reactive than copper and cannot displace it in a chemical reaction.
Even though gold and copper are in the same family, copper is much more reactive than gold. This is why Copper rusts more than gold, and why there are so many copper compounds (IE copper silicate...). Copper is higher in the family, giving it these characteristics.
Silver is harder than gold but softer than copper.
Gold is softer than copper. Copper is stronger and has a higher tensile strength compared to gold. This is why copper is often used for electrical wiring and plumbing where strength is important.
You are wrong. Copper is NOT more expensive than gold.
Copper is much more common than gold.
The volume of a substance is determined by its density and mass. Copper has a density of 8.96 g/cm³ and gold has a density of 19.32 g/cm³. Therefore, 1kg of copper would have a greater volume than 1kg of gold because copper is less dense than gold. In other words, the same mass of copper would take up more space than the same mass of gold due to their differing densities.
Copper is a better conductor of electricity than gold.
Yes. Brisbane is bigger in both population and area than the Gold Coast.
yes
Copper is much more abundant in the Earth's crust than gold is. It's also easier to mine.
Gold and Copper are chemical elements. No "minerals" can be extracted from them other than 'gold' and 'copper'. They can be extracted from the minerals or 'ores' named in the other answers herein.
