What is the best conductor Fe Cu Na Zn?
Copper (Cu) is the best conductor among Fe, Cu, Na, and Zn. It has high electrical conductivity due to its free electrons that are easily movable in the lattice structure. Copper is commonly used in electrical wiring and other applications where high conductivity is crucial.

How many grams of Cu(OH)2 can be produced from the reaction of 0.500g Cu with 30.0mL of 3.0M NaOH?
Cu + 2NaOH ---> Cu(OH)2 + 2NaSince we have a finite amount of two reactants we must first determine which is the limiting reactant. For Cu: n= m/M = 0.500 g/63.53 g/mol = 7.87E-3 mol For NaOH: n = CV = (3.0 mol/L)(0.0300 L) = 9.00E-2 mol Copper is by far the limiting reactant therefore we will use its amount to find the maximum Cu(OH)2 that can be yielded from the reaction. Since the above reaction scheme indicates that Cu and Cu(OH)2 are in a 1 to 1 ratio, their molar amounts are the same ie. at the end of the reaction there will be 7.87E-3 mol of Cu(OH)2 To find the mass that corresponds to this molar amount we multiply by the molar mass of Cu(OH)2 (97.56 g/mol): m=nM = (7.87E-3 mol)(97.56 g/mol) = 0.7678 g Therefore 0.500 g of Cu will yield 0.768 g (3 sig fig) of Cu(OH)2.
Is copper a good or poor conductor of electricity?
Metallic Copper (Cu) is an excellent conductor of electricity. It has a Specific Resistance of 1.682 X10-9 Ohms/cm, and an Electrolytic Potential of 0.344 volts.
Is pencil lead a resistor?
It is not a resistor, but not to say it's a good conductor. Although it lacks the metallic bonding that makes Cu such a good conductor, the sheets of graphite have hybridized sp2 orbitals, meaning there are long rows of p orbitals that can share electrons across the sheet, meaning it can conduct electricity. It has a resistivity of ~20uOhm meters, whereas as Cu has a resistivity of ~17nOhm meters.

Will a reaction occur if cu is added to silver nitrate solution?
None
How many cubic yards in 70 square feet?
sq feet to sq yards cu ft to cu yards you need depth added to your sq ft to get cu ft such as 70 sq ft x 4 in deep = 23.33 cu ft =.086 cu yd
Why the addition of Na2CO3 KSCN in the iodometric determination of Cu 2?
Na2CO3 is added to prevent oxidation of cu+ ions which are repeatedly formed by reaction of Cu++ and I-.So, to prevent oxidation co2 is used in retarding reaction
What is a small seedless raisin called and it starts with cu?

What happens to the atoms of copper when added dilute nitric acid is added?
(Cu)s + 2HNO3 --> Cu2+ + 2NO3- + (H2)gas
What is the chemical formula for bare copper wire?
The chemical formula for bare copper wire is Cu, which represents the element copper. Copper is a highly conductive metal commonly used in electrical wiring due to its excellent conductivity properties.
How many cu in are needed per each 14 AWG conductor?
For a 14 AWG conductor, the National Electrical Code (NEC) specifies that you need approximately 2 cubic inches (cu in) of space per conductor for proper installation in a junction box. This ensures adequate room for the conductors while preventing overheating and allowing for safe connections. Always consult local code requirements, as they may vary depending on specific circumstances.
What is the equation when zinc metal is added to a solution of copper II chloride?
The chemical equation for the reaction that occurs when zinc metal is added to a solution of copper II chloride is: Zn + CuCl2 -> Cu + ZnCl2.
What does 14k cu mean on gold?
"14k cu" on a piece of gold means that it is 14 karat gold with copper added to it. The "cu" indicates the presence of copper in the alloy mixture, which is commonly used to give gold additional strength and durability.
