The conversion factor from compound to element is actually
just based on the number of elements in the compound itself.
From the compound C12H22O11, we can say that there are 12
C, 22 H and 11 O, therefore the conversion factors are:
1 mol C12H22O11=12
moles of C
1 mol C12H22O11=22
moles of H
1 mol C12H22O11= 11 moles of O
Answer: The most commonly cited impact is deforestation, i.e., the clearance of forest or woodland. At a small spatial scale this may indeed be the case but on a larger landscape scale charcoal production most frequently results only in forest degradation. The contribution of charcoal to deforestation in the tropics is less than 7%. Charcoal production most frequently results in forest degradation. Most charcoal areas have the potential for rapid forest recovery.
Explanation:
The balanced reaction is
3Na3PO4 + 2CuSO4 ------> 3Na2SO4 + Cu3(PO4)2
To balance this reaction of double displacement, we see first that this reaction maintain the valence numbers of every atom.
Then, to have the same value of Na in the two sides of the reaction we multiply for the number of the other side. So,
(Na3PO4)x 2
(Na2SO4)x3
As we can see either, we need to balance PO4 cause there are two molecules of this in the reactant side, so we have two molecules of PO4 in the product either.
Then we get
3Na3PO4 + 2CuSO4 ------> 3Na2SO4 + Cu3(PO4)2
To probe that balance was correct, you can verify that the charges are exactly the opposite.
The correct answer for the question that is being presented above is this one: "<span>16.728 g."</span>
Given that
ΔHsolid = -5.66 kJ/mol.
This means that 5.66 kJ of heat is released when 1 mole of NH3 solidifies
When 5.57 kJ of heat is released
amount of NH3 solidifies = 5.57/5.66 = 0.984 moles
<span>molar mass of NH3 = 17 g/mole </span>
<span>1 mole of NH3 = 17 g </span>
So, 0.984 moles of NH3 = 17 X 0.984 = 16.728 g
