Answer:
you place it where you think it should be placed
Explanation:
The statements that describe a nuclear reaction are may involve a change in total mass, involve very high-energy changes, and involve changes in nuclides when decay takes place.
There are two kinds of nuclear reactions, that is, fission and fusion. Fusion involves the fusion of two light atoms into a heavier atom, while fission involves the splitting of an unstable isotope (with a high mass number) into stable elements of lower mass number, which vary in features from the parent atoms. Both the reactions discharge huge concentration of energies in the process.
1000 to the power 4 not so good at math but
Answer:
32.04°C will be the final temperature of the solution.
Explanation:
Moles of potassium chloride = 0.200 mol
MAs sof KCl= 0.200 mol × 74.5 g/mol= 14.9 g
Enthalpy of solvation of potassium nitrate =
Energy released when 0.200 moles of KCl is dissolved in water = Q
(1 kJ = 1000 J)
Heat released on dissolving 0.200 moles of KCl is equal to heat absorbed by water = Q
Mass of solution , m= 80.0 g +14.9 g = 94.9 g
Specific heat of water = c = 4.184 J/g°C
Initial temperature of the water =
Final temperature of the water =
32.04°C will be the final temperature of the solution.
Hey there!:
It is a solid at room temperature.
Take a look at the structure of the compound. It has 3 rings total, two of which are phenyl rings, 3 methyl groups and a pentyl group while there is only one OH. That is a lot of non-polar groups for just one polar group. This is why it is sparingly soluble in MeOH at RT, it really is not a very polar molecule (the general rule of thumb is 5 C's for every polar group for the molecular to be considered polar, this of course is a generalization).
I hope that helps.
