Cobalt because it has an atomic mass of 58 and 33 neutrons.
water in scientific knowledge is H20
Answer:
-0.85KJ
Explanation:
Given N2(g) + H2(g) <--->2NH3(g)
Kp =[ P(NH3)]²/[P(H2)]³[P(N2)]
Where P is the pressure of the gas
P(H2)b= P(N2) = 125atm
P(NH3) = 200atm
Kp = 2²/(125)³(125)
Kp = 2.048 ×10^-6
∆G = -RTlnKp
R =0.008314 J/Kmol
T = 25 +273/= 298k
= 8.314 ×10^-3 × 298 × ln(2.048 ×10^-6)
= -0.008314 × 298 × (-13.099)
= 32.45KJ
∆G = ∆G° + RTlnKp
∆G = -33.3 + 32.45
∆G = -0.85KJ or -850J
I think the mass the mass was less than the original because a gas was released into the atmosphere. The mass in a chemical reaction is constant in a closed system according to conservation of mass law. However, if a chemical reaction is completed in an open system, mas changes may occur. In our case i think the change in mass was due to the release of hydrogen gas from the reaction to the atmosphere.
<span>This is Pseudoscience. The scientists didn’t study their
experiment, they would have to prove their claim more than once, and they
assumed things before actually studying it. </span>
