The answer is 1,560 hope this helps if u multiply all of it
Well as an spontaneous reaction will have a negative gibbs free energy (delta g) and a positive e cell and also the E cell is also measured in V, then your answer is the first one: ΔG = –295kJ, E°cell = +1.53 v. Hope this works
Answer:
1) Has a smaller radius than oxygen because of the increased electromagnetic attraction of the nuclei
2) Has a smaller radius than chlorine because all the electrons of F have lower energy levels and have less repulsion of other electrons and hence are more attracted to the nuclei .
Explanation:
Further the electrons are from the nuclei , the bigger the atomic radius is.
(+) attraction of electrons to the nuclei, (-) repulsion of the electrons away from the nuclei.
1) From O to F:
(+) there is one more proton --> Stronger positive charge of the nuclei means that the electrons are attracted more , then they come closer to it and therefore the radius decreases
(-) There is one more electron --> Every electron is repulsed by others away from the nuclei --> the radius increases. But this effect is not so strong because the new electron is added at the same energy level.
Overall the (+) effect is stronger than the (-) effect --> Radius decreases from O to F
2) From F to Cl
(+) there is one more protons --> Same effect as before
(-) There is one more electron --> Every electron is repulsed by others away from the nuclei. But this time the new electrons have a higher energy level --> Meaning that they are less attracted and hence the radius increases.
And also the other inner layers of electrons (electrons of lower energy levels) repulse this new external layer of electrons more effectively than the case of O --> Strong repulsion effect (called electron shielding effect) --> Radius increases
Overall the (-) effect is stronger than the (+) effect --> Radius increases from F to Cl (or decreases from Cl to F)
Answer:- 
Solution:- First of all we calculate the heat absorbed or released when the solute is added to the solvent. Here the solute is LiCl and the solvent is water.
To calculate the heat absorbed or released we use the formula:
q = heat absorbed or released
m = mass of solution
s = specific heat capacity
and 
= change in temperature
mass of solution = mass of solute + mass of solvent
mass of solution = 5.00 g + 100.0 g = 105.0 g
(note:- density of pure water is 1 g per mL so the mass is same as its volume)
= 33.0 - 23.0 = 10.0 degree C
s = 
Let's plug in the values in the formula and calculate q.
q = 
q = 4389 J
To calculate the enthalpy of solution that is 
we convert q to kJ and divide by the moles of solute.
moles of solute = 
= 0.118 moles
q = 
= 4.389 kJ
= 
Since the heat is released which is also clear from the rise in temperature of the solution, the sign of enthapy of solution will be negative.
So,
nona-, 9 it shows the prefix with the correct corresponding number
Explanation:
This prefixes are used commonly in chemistry to name compounds and you may find them when hydrocarbons are named.
We have:
penta- for 5
hexa- for 6
hepta- for 7
octa- for 8
nona- for 9
deca- for 10
The correct answer for the question is nona-, 9.
