Answer:
I. 56
II. c is the speed of light in vacuum.
III. 385.180×10¯²⁷ Kg.
Step-by-step explanation:
I. Determination of the value of p.
²³⁸₉₂U + ¹₀n —> ¹³⁹ₚBa + ⁹⁷₃₆Kr + 3 ¹₀n
92 + 0 = p + 36 + 3(0)
92 = p + 36
Collect like terms
92 – 36 = p
56 = p
Therefore, the value of p is 56
II. Determination of the meaning of c
ΔE = Δmc²
In the Einstein's equation above,
E => is the energy
m => is the mass
c => is the speed of light in vacuum.
III. Determination of the total mass of the element formed after the reaction.
From the reaction above, the elements formed after the reaction are:
Barium–139 and Krypton–97. Thus, we can obtain the total mass of the elements formed as follow:
Mass of Ba–139 = 232.560×10¯²⁷ Kg
Mass of Kr–97 = 152.620×10¯²⁷ Kg
Total mass =?
Total mass = mass of Ba–139 + mass of Kr–97
Total mass = 232.560×10¯²⁷ + 152.620×10¯²⁷
Total mass = 385.180×10¯²⁷ Kg
