What gas is given off when acid is mixed with copper?
When acid is mixed with copper, the gas given off is hydrogen. This reaction produces hydrogen gas, as the acid dissolves the copper to form copper ions and hydrogen gas is released as a byproduct.
Solvent and solute of a brass cooking pot?
I do know that a mixture of copper and zinc create braa but i do not know for sure which is the solvent and which is the solute. I belive the copper is the solvent and the zinc is the solute. Best of luck answering this question ! - I do know that a mixture of copper and zinc create braa but i do not know for sure which is the solvent and which is the solute.

Why is brass not a metal?
All materials are magnetic in some form. Copper, which is diamagnetic, is affected negligibly by magnetic fields because it has no permanent magnetic moment and a magnetic susceptibility less than 0. This is the same reason materials such as water, wood, oil, plastic, gold, mercury, and bismuth are unaffected by common magnetic fields. Given a strong enough magnetic field, however, the effect can be seen. Diamagnetic materials, such as copper, are repelled from the source of the magnetic field.
How can you tell the difference between gold and brass?
Gold is is much denser than brass (given the same volumesof the two metals gold is much heavier)Gold will not tarnish when exposed to most acids such as acetic acid (vinegar). phosphoric acid (Coca Cola) or alkali such as dish washing detergent.
How much oxygen reacted with the piece of copper?
The amount of oxygen reacting with copper can be determined by the reaction stoichiometry. For example, in the reaction of copper with oxygen to form copper oxide, two moles of oxygen react with one mole of copper. From the given amount of copper and assuming all the copper reacted to form copper oxide, you can calculate the corresponding amount of oxygen that reacted with the copper.
Why are copper and brass utensils given a coat of tin-give reasons?
Because copper is mildly posionous. The tin layer prevents copper from leaching into the food. Brass is an alloy that contains copper, so the same reason applies there.
What type of coating is given to non stick cooking utensils?
Teflon
Are the fumes given off molten brass toxic?
Yes, the fumes given off by molten brass can be toxic due to the presence of zinc, copper, and other metals in the alloy. Exposure to these fumes can cause health issues such as metal fume fever, respiratory irritation, and in some cases long-term respiratory problems. It is important to take proper precautions when working with molten brass to minimize exposure to these fumes.
Will zinc alloy jewelry tarnish?
Yes, zinc alloys e.g brass will tarnish given the "right" conditions.Zinc alloys contain copper, and copper is one of the most tarnish-prone metals there is, so any alloy containing copper will tarnish eventually, depending on the percentage of copper alloyed.
What does the electrical term - copper clad - signify?
It is much like electroplating. To make something more conductive it is given a coating or cladding of another more conductive element. Take copper clad ground rods. The original ground rod is just a steel rod. To make is more conductive a coating of copper is plated to it. This now enhances the steel ground rod buy improving its conductivity with the soil around it and secondly giving it an anti rust covering that will last the life of the ground rod.
What is characteristics of wire?
A wire has to be made of a conducting metal such as copper or aluminium, and it has to be thick enough to carry the required amount of electric current. Wire is often given an enamel coating to insulate it Wires are often stranded which gives flexibility.
What is thermal conductivity of brass a?
The thermal conductivity of brass is around 109-130 W/mK, depending on the specific composition of the brass alloy. Brass is a good conductor of heat, making it useful in applications where heat transfer is important.
If block of brass made up of copper of density 9 g per cm and zinc of 100 cm and density of 8.5 g per cm what are the masses of the copper and zinc used to make this block of brass?
I believe the question is Block of brass made of copper at density 9g/cm3 and zinc 100 cm3 with density of 8.5g/cm3 The question don't contain sufficient data to calculate. Brass may have zinc content varies between 5 - 15% this ratio meant to be fix to calculate out ratio copper use. Let presume fix zinc content to 10% that is 90% copper use Zinc additive is 100 x 8.5 = 850 gram Copper additive is then 850x90/10 = 76,500 gram = copper volume of 76,500/9 = 850 cm3 Net weight of this block is then 850+76,500 = 77,350 gram
Why does a potato acquire a greenish deposit at the anode during electrolysis of potato?
You do not mention what you are using as the anode and cathode, but i would assume that given the green colour you are using copper or brass perhaps as the anode, and it is breaking down into a copper carbonate(which is green). By applying electrical current to the circuit you are speeding up the conversion of copper to copper carbonate(or similar).
In painting what term is given to the first coating applied to a surface that is to be painted on?
Primer.
What is copper commonly used for?
Copper flashings on roofs , copper water supply, copper drainage (DWV) copper gas lines (medical etc) copper for electric, copper for art work, copper mixed with other metals to create an alloy like bronze or brass, copper nails to prevent rusting when exposed to the elements, used in fire suppression systems and air conditioning and heating applicationsCopper is gold wire electricety dumb people hello:)
What gas is given off when acid is mixed with copper?
