Answer:
3%
Explanation:
as error occurred is 1.5(error value) so 1.5 is 3%of 50(original value)
Answer is: a suspension.
Suspension is a heterogeneous mixture (solute particles do not dissolve), that contains solid particles (for example nickel sulfide or NiS) sufficiently large for sedimentation.
The internal phase (solid nickel sulfide) is dispersed throughout the external phase (water).
Another example of a suspension is sand in water.
You already write there it's answer ಠಿ_ಠ
Answer:
Time=345.7 min
Explanation:
It is an example for Faraday's first law of Electrolysis
It states that the amount of substance deposited is directly proportional to the amount of electricity passed.
W=Zit
Z=E/96500
W= E it/96500
And E=58.7(molar mass of Ni)/2(charge on Ni)=29.3
t=W96500/E i
= 29.6x96500/29.3x4.7
= 20742.1 sec
=345.7 min
