Answer:
The answer is b. Carbon Tetrachloride
Explanation:
Let's discard the other options:
a. It couldn't be carbon chloride because there are four (4) chloride ions in the molecular formula. The molecular formula for the carbon chloride must be CCI. So, this answer is wrong
c. It could be monocarbon tetrachloride because there are 4 chloride ions and 1 carbon ion, but it's not necessary to use the prefix "mono" because there is just one carbon ion in the formula. In that way, when we mention carbon in the name, there is implicit that there is just one carbon atom in the formula. So, this answer could be ok, but isn't the best.
d. It couldn't be calcium chloride because there isn't any calcium ion or atom in the formula. The molecular formula for the calcium chloride must be CaCI. So, this answer is wrong
Answer: B. endergonic, not spontaneous
Explanation:
Endergonic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and 
for the reaction comes out to be positive.
The Gibbs equation is:
= Gibb's free energy change
= enthalpy change
T = temperature
= entropy change
A reaction is non spontaneous when = Gibb's free energy change is positive
Thus the reaction has to be endergonic.
Answer:
C-BY LOSING ONE OR MORE ELECTRONS
Hydrologists primarily study water, i think
Delta E= R[1/n^2 (initial) - 1/n^2 (final) ]
so transition n=3 to n=1 will emit more energy
