Answer:
6 moles
Explanation:
Take a look at the balanced chemical equation for this synthesis reaction
N
2(g]

NH
3(g]
Notice that you have a
1
:
3
mole ratio between nitrogen gas and hydrogen gas. This means that, regardless of how many moles of nitrogen gas you have, the reaction will always consume twice as many moles of hydrogen gas.
So, if you have
2
moles of nitrogen taking part in the reaction, you will need
2
moles N

This is true, you start at 270 bones at birth, which is hard to believe, because I thought the more younger, the more less they have. But hey, that wasn't true!
Answer:
LOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOONGGGGGGGGGGGGGGGGGGGGGGGGGGG
Explanation:
Answer is (b)
2,3,1 is the stoichiometry
The values in front of the elements are the stoichiometric values
(Since Al2Br6 has no value in front, it's considered 1)
