The half reactions as they occur at each electrode
is as follows
at the anode Sn(s) =sn^2+(aq) + 2e -
at the cathode 2 ag^+(aq) + 2e - = 2Ag (s)
net cell reaction = Sn (s) + 2Ag^+(aq) = sn^2+ (aq) + 2 Ag (s)
The density of metal block in grams per cubic centimeter is 10.70 g/cm³.
Given,
Mass of metal block = 5.16 lb
1 lb = 453.592 g
5.26 lb = 2340.536 g
The volume of metal block = 14 in 3
1 in = 2.5 cm
1 in 3 = 15.625 cm³
14 in 3 = 218.75 cm³
Density is defined as the mass per unit volume of a substance. Or, it is the ratio of mass to the volume of the substance.
As we know,
Density = mass/volume
Or, density = 2340.536 / 218.75
Or, density = 10.70 g/cm³
Therefore, the density of the metal block is 10.70 g/cm³.

Answer:
See explaination
Explanation:
Since X is more reactive than Y
=> X is oxidized to X2+ and Y2+ is reduced to Y
Overall cell reaction is:
X(s) + Y2+(aq) => X2+(aq) + Y(s)
please kindly see attachment for further solution.
Reactivity is a chemical
property of a substance. According to EPA regulations, it is normally unstable
and readily
undergoes violent change without
detonating. it can explode or violently react when exposed to water, when
heated, or under STP.
