Answer:
0.00120 moles of electrons had traveled through the wire.
Explanation:
Amount current passed in 132 seconds = 0.880 A
Charge passed in 132 seconds = Q
Number of electrons = N
Magnitude of charge on an electron = q =
1 mole = ions/ particles/ atoms
The moles of electron in electrons:
0.00120 moles of electrons had traveled through the wire.
Answer:
Explanation:
Amount of silver
= 1.25 x .9 = 1.125
amount of copper = 1.25 x .1 = .125
equivalent weight of silver = 108
gram equivalent of silver in the alloy = 1.125 / 108 = .01041
This will precipitate in the form of copper in equivalent amount of copper
equivalent of copper precipitated = .01041
grm of copper for silver = .01041 x equivalent weight of copper
= .01041 x 63.5 / 2 = .3305 gram
Total copper precipitated
= .125 + .3305
= .4555 gm
Answer:
32.57g
Explanation:
mass = mole x molar mass
mass of LiBr = 0.375 x 86.85
mass = 32.57g
The minimum would be 0 degrees Celsius or 32 degrees Fahrenheit.
Yes and no b/c tungsten is both conductive nd certainly non-conductive
