Answer:
20.54 g of H₂O
Explanation:
Since you already have a balanced equation, the next step is to see the ratio between the ammonium nitrate and water in the equation:
NH4NO3(s)—N2O(g)+2H2O
1 mole of ammonium nitrate produces 2 moles of H2O
So we have the ration:
Let's leave that for later use.
Next step is to covert the mass given into moles. We do that by getting the molar mass of the given and using that as a conversion factor:
Element number of molar mass
atoms of each element
N = 2 x 14.01 g/mole = 28.02 g/mole
H = 4 x 1.01 g/mole = 4.01 g/mole
O = 3 x 16.00 g/mole = <u>48.00 g/mole </u>
80 .03 g/mole
Now we can convert:
Now we can use this to determine how many moles of H2O this would produce by using the ration we solved for earlier.
And we convert that by getting the molecular mass of H2O, which is 18.02 g/mole:
But this is only if the whole 45.7 g of ammonium nitrate is used up.
Answer:
The diagram is attached.
Explanation:
Peptide just refers to two or more amino acids liking together. A dipeptide consists of two amino acids linking together. A polypeptide is more that two amino acids linking together.
