What else can I help you with?
Is it a copper OR zinc penny that dissolves in phosphoric acid?
A zinc penny would dissolve in phosphoric acid, not a copper penny. Zinc reacts with phosphoric acid to form zinc phosphate and hydrogen gas. This reaction does not occur with copper, as copper is a more stable metal and does not react with phosphoric acid in the same way.
What is more reactive zinc or copper sulphate?
Zinc is more reactive than copper sulfate. When zinc is placed in a solution of copper sulfate, a displacement reaction occurs where zinc displaces copper from the solution, forming zinc sulfate and copper metal.
What two metals compose the alloy brass?
Zinc and Copper Copper and zinc make up the mixture (alloy) brass.
What happens when zinc is dipped in a copper sulfate solution Zinc is higher on the activity series than copper.?
When zinc is dipped in a copper sulfate solution, zinc will undergo a single displacement reaction where it will replace copper in the solution to form zinc sulfate and copper. This is because zinc is higher on the activity series than copper, so it is able to displace copper in the solution.
What is mixed with copper to make brass?
Brass is mainly an alloy of copper and zinc. Some alloys do have small amounts of arsenic added also.
How does the mass of zinc penny compare to a copper penny?
Copper pennies (95% copper, 5% zinc) weigh 3.11 grams. Modern zinc pennies (97.5% zinc, 2.5% copper) weigh 2.5 grams.
What is better copper or zinc BBS?
They are both about the same.
How does Daniell cell produce electricity?
A daniell cell is a system comprising a copper container, a solution of copper ions, a porous pot, a solution of zinc ions and a zinc rod. When the zinc rod and the copper container are connected by a wire, the zinc rod is oxidised to zinc 2+ ions, which releases two moles of electrons per mole of zinc decayed. These electrons flow round the wire to the positive electrode, the zinc container, where the copper ions in the solution are reduced to copper metal. If components eg. A light bulb, are placed within the circuit, the electron flow from the zinc to the copper electrode will power the bulb.
Is it a copper OR zinc penny that dissolves in phosphoric acid?
A zinc penny would dissolve in phosphoric acid, not a copper penny. Zinc reacts with phosphoric acid to form zinc phosphate and hydrogen gas. This reaction does not occur with copper, as copper is a more stable metal and does not react with phosphoric acid in the same way.
Can copper and alluminium wire of same length and diameter have same resistance?
No, copper and aluminum wire of the same length and diameter will not have the same resistance. Copper has a lower resistivity than aluminum, so a copper wire will have lower resistance compared to an aluminum wire of the same length and diameter.
Does copper and brass have the same density?
No, copper and brass do not have the same density. Copper has a density of around 8.96 g/cm³, while brass, which is an alloy of copper and zinc, has a density that varies depending on the specific composition. Generally, brass has a lower density than copper due to the addition of zinc.
What is more reactive zinc or copper sulphate?
Zinc is more reactive than copper sulfate. When zinc is placed in a solution of copper sulfate, a displacement reaction occurs where zinc displaces copper from the solution, forming zinc sulfate and copper metal.
Is brass the same thing as copper?
Depends on what the usage is do you want YELLOW Brass 60% Copper 40% Zinc Or do you want RED BRASS? 85% Copper 15% Zinc
Does copper displace zinc from zinc sulphate?
No, zinc will displace copper from copper sulphate but not the other way around.
Does zinc usually combine with copper?
Alloys of zinc and copper are well known. There are no chemical compounds of zinc and copper.
What two things happen when zinc is added to copper sulphate?
The Zinc will displace the copper. It will become Zinc Sulphate. The word equation will be Zinc + Copper Sulphate -----> Copper + Zinc Sulphate. Hope this helps!
What two metals compose the alloy brass?
Zinc and Copper Copper and zinc make up the mixture (alloy) brass.
