Proton mass = 1.00728 amu
neutron mass = 1.0086 amu
electron mass = 0.000549 amu
so the mass is :
(7 * 1.00728) - (7 * 1.0086) - (7 * 0.000549) - 14.003074
= 0.11235 amu
You may find in the attached picture the structure for compound (A) and (B).
Explanation:
The compound (A) and (B), which are haloalkanes, will undergo base-promoted E2 elimination and it will form the alkene (C) with the double bond in the second position. Zaitev's rule, which is an empirical rule, tell us that the halogen will leave with the hydrogen from the neighbor carbon which have the lowest amount of hydrogen, in the picture this specific hydrogen have a blue color.
Further compound (C) it will form compound (A), as a major product, by addition of hydrobromic acid. The Markovnikov's rule, which is also empirical, tell us that the halogen from the acid will add the carbon, involved in the double bond, that have the lowest amount of hydrogen.
Compound (C) will participate to a hydrogenation reaction to form 2,6-dimethylheptane.

The final temperature of the water will be 31.2 °C... i don’t know the second one sorry :(
Answer:
False.
Explanation:
Fusion reactions are not yet commercially viable because they require extremely high energies to initiate and sustain a reaction.
