A copper sheet is made of... surprise... copper. No gold.
Copper and gold; copper is brown when in a pure state (green is more familiar, but that's actually an oxidized copper), and gold is yellow.
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.
Palladium, zinc, copper and nickel can be combined with gold. There may be others.
Nitric acid can dissolve copper but not gold. Gold is resistant to most acids, including nitric acid, which is commonly used to dissolve copper.
To mix copper alloy for 1 gram of 24k gold to create 21k gold, you need to reduce the gold content from 24k (100% gold) to 21k (87.5% gold). This means you will require 0.875 grams of pure gold and 0.125 grams of copper alloy (which typically contains copper and possibly other metals). To achieve this, mix approximately 0.125 grams of copper with your 0.875 grams of 24k gold.
Some metals that are not silver gray in color include gold (yellow), copper (orange-red), brass (yellow-brown), and bronze (reddish-brown).
Sheet metal refers to how the metal is layed out rather than what type of metal. So therefore sheet metal can be made out of metals such as gold, brass, copper and steel. If the type of metal used is magnetic then so is the sheet metal.
Yes
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.
Well from what i know they are gold silver medal copper and wood. This is 100% true.
We often hear that gold is the heaviest metal, but is this really true? In reality, the answer to this question depends on the density of each metal. Iron, gold, copper and silver all have different densities which makes it difficult to determine which one is the heaviest.
A copper sheet coated with Mercury is used to capture very fine gold dust, as at a beach shore. But I know of no such use using brass.

To calculate the weight of a copper cathode sheet, you would first need to know the dimensions of the sheet (length, width, and thickness). Then, you can use the formula: weight = density of copper x volume of the sheet, where the density of copper is 8.96 g/cm3. Multiply the volume (length x width x thickness) by the density to find the weight in grams.

Copper into gold, means putting copper powder in gold salt solution. Because copper is closer to hydrogen then gold, in the electromotive scale, it will dissolve, freeing the gold
