Pulmonary tuberculosis, that is tuberculosis of the lungs, makes up the vast majority of the cases. It is an ancient disease. Neolithic skeletons (4500 B.C.), and Egyptian Mummies (1000 B.C.) have been found with tubercular lesions on their bones
It attempts to describe and account for the properties of molecules and atoms and their constituents—electrons, protons, neutrons, and other more esoteric particles such as quarks and gluons.
We can write the balanced equation for the galvanic cell by using the oxidation and reduction half-reactions. In the anode, Ni(s) is oxidized and produces aqueous Ni2+:
Ni(s) → Ni2+
while in the cathode, Cu2+ is reduced and deposits copper:
Cu2+ → Cu(s)
We now balance the charge of each reaction by adding electrons to the side of the equation with the greater charge:
Ni(s) → Ni2+ + 2 e-
Cu2+ + 2 e- → Cu(s)
Finally, we add the half-reactions to obtain the overall balanced equation for the galvanic cell:
Cu2+(aq) + Ni(s) → Ni2+(aq) + Cu(s)

Answer:
0.89L ( 2 decimal place)
Explanation:
Using Combined Gas law.
(
P₁V₁)/T₁ = (P₂V₂) / T₂
P₁ = 1.00 atm
V₁ = 1.55L
T₁ = 27.0 °C = converting to kelvin ( 27 + 273k) = 300k
P₂ = same as P₁ = 1.00 atm
V₂ = ?
T₂ = -100°C = converting to kelvin ( -100 + 273k) = 173k
(1 x 1.55)/300 = (1 x V)/173
1.55/300 = V/173
V / 173 = 0.00516666666
V = 173 x 0.00516666666 = 0.89383333333 ≈ 0.89L ( 2 decimal place)
