Combine the two solutions. If the resulting salt is basic, you know the base was stronger. If you end up with an acidic salt, the acid was stronger.
Po, (218, 84) - Alpha Particle (4, 2) = (218 - 4, 84 - 2) = <span>(214 , 82)</span>
(214 , 82) - 2Beta = (214, 82 - 2*(-1)) = (214 , 84)
Polonium has atomic number of 84.
So answer = Polonium-214
1 lbs ----------- 0.453592 kg
123 lbs -------- ??
123 x 0.453592 / 1 => 55.7919 kg
Answer:
ΔG° = -8.8 kJ/mol
Explanation:
The standard Gibbs free energy of reaction (ΔG°) can be calculated using the following expression.
ΔG° = ΔH° - T.ΔS°
where,
ΔH°: standard enthalpy of reaction
T: absolute temperature
ΔS°: standard entropy of reaction
At 298 K (the temperature that is usually used), ΔG° for the hydrolysis of lactose is:
ΔG° = ΔH° - T.ΔS°
ΔG° = 0.44 kJ/mol - 298 K × 0.031 kJ/mol.K
ΔG° = -8.8 kJ/mol
