Potassium is more reactive...
Nuclear energy produces wastes in the form of spent nuclear fuels, this is normally a mixture of radioactive isotopes and heavy metals, both of which are toxic and pose a great danger to the environment. Additionally, irradiated materials surrounding the reactor which become radioactive from exposure to the radiation produced by the reactor and which should be disposed off at the end of the life of the reactor and processes involved. Also the breeder reactors convert unusable radioactive isotopes into fissionable isotopes, thus allowing more of the fuel to be used and reducing amount of fuel rod waste.
<span>SnSO4 • 7H2O
This formula has 2 part
1) </span>SnSO4 - <span>tin (II) sulfate
2) 7H2O - </span><span>heptahydrate (that means 7 molecules of water).
So full name is </span><span> tin (II) sulfate heptahydrate.</span>
Answer:
2. ΔG is zero, ΔH is positive, and ΔS is positive
Explanation:
When the ice is being converted to water ate 0ºC and 1 atm, there is an equilibrium between the solid and the liquid. At the equilibrium point, ΔG (the free energy) is zero. It is negative for spontaneous reactions and positive for nonspontaneous reactions.
For the phase change happens, the ice must absorb heat from the surroundings, so it's an endothermic reaction, and because of that ΔH (the enthalpy) must be positive. It is negative for exothermic reactions.
In the liquid state, the molecules have more energy and the randomness is higher than the solid-state. The entropy (S) is the measure of the randomness, so if it's increasing, ΔS must be positive.
