4. 346g of Sodium oxide (Na2O) undergoes a decomposition reaction. How many grams of oxygen gas and sodium should be produced? If I harvest 210g of sodium, what was the percent yield? Unbalanced equation: Na + O2 → Nao

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 m.

"the periodic table is arranged in order of atomic number."

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.
