Answer:
(a) when both the liquid are mixed, they become completely miscible as the intermolecular forces between them are equal to the intra molecular forces
(b) since the magnitude of intermolecular force = intra molecular forces, Delta H solution=0
(c) Delta H solute = positive
Delta H solvent = positive
Delta H mix = negative
Explanation:
So half life is the time taken for a sample to decay to half its original mass, its a constant and applies to any original mass, it could be 5g or 1kg, it will take the same amount of time for the original mass to half. In this case the half life is 3 days.
After 3 days the sample will be at half its original mass, now 50g.
Now we can treat the 50g as if its a new sample. After another 3 days (6 days in total) there will be half of 50g left, = 25g.
Exothermic reaction = the term exothermic process describes a process or reaction that releases energy from the system to its surroundings, usually in the form of heat, but also in a form of light, electricity,
Endothermic reaction = An endothermic process is any process with an increase in the enthalpy H (or internal energy U) of the system. In such a process, a closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system.

Answer:
A magician I saw once made a painting of a dove come to life. The bird literally flew out of the painting.
That happened 10 years ago and I'm still wondering how that is even possible.
