An aqueous solution of lead (II) nitrate Pb(NO3)2 is mixed with aqueous sodium phosphate Na3PO4 to produce solid lead (II) phosphate Pb3(PO4)2 and aqueous sodium nitrate NaNO3

3Pb(NO3)2 + 2 Na3PO4
—> Pb3(PO4)2 + NaNO3

a) How many moles of sodium nitrate are produced from 12.3 moles of Na3PO4?
b) Calculate the grams of Pb(NO3) needed to react with 8.5 moles of Na3PO4
c) How many moles of NaNO3 are produced from 152.3 g of Na3PO4
d) Calculate the amount of Pb(NO3)2 in grams needed to react with 108 g of Na3PO4

h let me think

i'm pretty sure its b i might be wrong though!

the correct answer to this question is 2

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.
