Answer:
Gold is present in electronic wastes like smart phones,TV sets and computers etc.It is necessary to recover gold effectively.Recovering precious metal from electronic waste could help to reduce the environmental impact and cut carbon dioxide emissions
Simply one who think about the target metal without disturbing the other major impurities will be the idea solution for the industrial scale gold recovery from E-waste... In our lab we have developed the process which was patented in India... hope soon it will publish into the public domain.... PROCESS FOR THE RECOVERY OF GOLD FROM MANUALLY DISMANTLED GOLD COATED E-WASTE
Use of both physical and biological processes may help in a better recovery of Gold. Several microorganisms have been discovered which are efficient in solubilising gold from the e-wastes.

<span>ppm = mg/L
or
Kg solution
Mass % = Mass of Solute/Mass of solution
0.0390 M = x moles/1L
x = 0.0390 Moles of F-
0.0390 mol x 18.998403 g/mol = 0.7409 g
PPM:
1mg = 1000g
0.7409g = 740.9mg
740.9mg/1L = 740.9mg
Mass Percent:
density 1 g/mL
thus
1 g = 1 mL
thus
1 L = 1 kg
thus
1 L = 1000 g
so,
(0.7409 g/1000 g)*100
= 0.07409% (m/m)</span>
Because of the ammount of water and the boling point of the Ganga River has changed due to the mixtures of different kind of chemicals and acids

Answer:
Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries. Volcanoes are one kind of feature that forms along convergent plate boundaries, where two tectonic plates collide and one moves beneath the other.
