What is another name for homogeneous mixtures other than solution
Ede4ka [16]

Answer and Explanation:

The answer is solution. However, single-phase alloys are solid metal solutions, and colloidal suspensions are homogenous mixtures that are not solutions. Homogenized milk, for example, is a colloidal suspension that technically meets the definition of a homogenous mixture because the milk fats, though immiscible with the whey (the aqueous phase), are tiny beads evenly distributed through the whey, and do not separate according to density, as they do in non-homogenized milk.

Hope this helps. :)

How much silver is produced is 15.00 grams of cu is added to the solution of excess silver nitrate?
il63 [147K]
First write out the balanced equation. 3Cu+2Ag(NO3)3=2Ag+3Cu(NO3)2
Then convert copper from grams to moles
15 g*1 mol cu/63.54 g= 15/63.54 mol cu
Then use the mole ratio to convert Moles Cu to Moles Ag
15/63.54 moles Cu* 2 moles Ag/3 moles Cu
The final awnser is (15*2)/(63.54*3) moles Ag =0.157 moles Ag. If the question wants the answer in grams, convert from moles Ag to grams Ag.
0.157 moles Ag*107.87 g Ag/ mol Ag=16.98 g Ag

A voltaic cell using Cu/Cu²⁺ and Sn/Sn²⁺ half-cells is set up at standard conditions, and each compartment has a volume of 345 m
Nadusha1986 [10]

The mass of copper deposited is 9.589 g .

Given ,

A volatile cell using Cu/Cu2+ and Sn/Sn2+ half cells is set up at standard conditions ,and each compartment has a volume of 345 ml .

current = 0.17 A

time = 48 hrs =48 (60) (60) =172800 sec

we know , I = Q/t

thus , Q ,charge= It = 0.17 (17280) =29376 C

Then ,atomic mass of copper is 63 g

And valency of Cu is 2.

Thus , the equivalent mass of copper is 63/2 = 31.5

We know , 96500 coulombs of electricity produce copper = 31.5 g

29376 C of electricity produce copper =9.589 g

Hence , 9.589 g of Copper is deposited .
