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.
Since the choices are missing, I will tell you why non-metals tend to form covalent bonds. You can then link this answer to the best fit choice.
Ionic bond is only formed due to an electrostatic attraction force between ions of opposite charges which cannot happen in case of non-metals whose ions are mostly anions.
On the other hand, a covalent bond is formed due to electrons being shared among different atoms. This conditions is satisfied for the bonds between non-metals
Maybe the first or third ☝️ one
the correct answer would be mixture because compound uses the same element
Answer:
The answer to your question is Molarity = 0.238
Explanation:
Data
Molarity = ?
number of moles = 0.285
volume = 1.2 L
Molarity is a unit of concentration that relates the moles of a substance by the volume in liters.
Formula
Molarity = moles / volume
Substitution
Molarity = 0.285 / 1.2
Simplification and result
Molarity = 0.238
