Hydrogen gas can be produced by reacting aluminum with sulfuric acid. How many grams of sulfuric acid are needed to completely react with
15.0 mol of aluminum?
Al(s) + H2SO4(aq) ® Al2(SO4)3(aq) + H2(g)

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.

< 3

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
