Copper can be drawn into thin wires. how many meters of 34-gauge wire (diameter 6. in) can be produced from the copper in 5.01 lb of covellite, an ore of copper that is 66% copper by mass? (hint: treat the wire as a cylinder: v of cylinder ; d of copper 8.95 g/cm3.)

Covellite ore contains 66% copper by mass thus, in 5.01 lb of covellit, mass of copper will be :

Converting mass into grams,

1 lb=453.592 g

Thus, 5.01 lb=2272.498 g

The density of copper is , calculate volume as follows:

Comparing this volume of cylinder because shape of wire is cylindrical.

Since, 34 gauge=0.00630 inch

Convert inch into cm,

1 inch=2.54 cm

Thus,

0.00630 inch=0.016002 cm

The diameter of wire is 0.016002 cm, calculate radius as follows:

Rearranging equation for volume and putting the values,

1 cm=0.01 m thus,

Thus, the length of wire is .

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
