Copper sulfate plus iron equals?
The iron is higher in they reactivity scale than copper , Therefore the copper will be replaced by iron to make iron sulfate and copper by itself.
What is the difference between sludge and scale?

Which is harder-------------- copper or diamond?
Diamond is much harder than copper. On the Mohs hardness scale (higher numbers are harder), diamond is a 10 and copper is somewhere between 3 and 4.
Is any reaction happens with copper and steel bar mixed?
If you are asking if there will be a chemical rection between the copper and steel, such as an explosion, no. Metals have a property called nobility, which measure a metals resistance to corrosion when in contact with another metal. The further apart they are on the nobility scale, the worse the corrosion. Copper and stainless steel are not very far apart. Copper and aluminum are a poor mix. The Galvanic Scale should be checked to see if certain metals in contact will accelerate corrosion.
What is standard hydrogen electrode?
Standard hydrogen electrode forms the basis of the thermodynamic scale of oxidation reduction potentials.
When burning copper and rubber what makes the different colors in the flame?
Any piece of copper heated will do the same thing. When heated, the colored coating on the copper is called "scale," and consists of a thin layer of copper oxide on the surface of the copper. Depending on the thickness of the layer and its temperature, the scale can be some very interesting colors, such as red, blue, brown, and pink.
What black metal gave blacksmiths their name?

The degrees are the same, but the zero points differ.
How does the Richter scale differ from the Marcalli intensity scale?
Richter scale measures magnitude of an earthquake, while Marcalli scale measures the strength of an earthquake.
Why does copper change color when heated?
When copper is heated a colored coating is formed. This coating is called "scale", and consists of a thin layer of copper oxide on the surface of the copper. Depending on the thickness of the layer and its temperature, the scale can be some very interesting colors, such as red, blue, brown, and pink, and at higher temperatures, black. The effect is quite noticeable on soldering irons with copper tips.
