Please answer these quickly. :)

Q.1

a) 1 mol of N2 requires 3 moles of H2

so 4 moles of hydrogen will require = 4/3 = 1.33 moles

Answer of A) 1.33 moles

b) 2.5 moles of nitrogen gas were require to produce 5.00 moles of NH3

c) 7.5 moles of hydrogen gas were require to produce

5.00 moles of NH3

Q.2

a) 6 moles of H2 gas were require to make 6.00 mol H2S

b)24 moles of H2 gas were required to react with 3 moles of S8

c)56 moles of H2S are produced from 7 mol of S8

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

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.
