Ammonium nitrate decomposes to dinitrogen monoxide and water. If given 45.7 grams of ammonium
statuscvo [17]

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:

\dfrac{1\;mole\;of\;NH_4NO_3}{2\;moles\;of\;H_{2}O}

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:

45.7g\;of\;NH_4NO_3\times\dfrac{1\;of\;NH_4NO_3}{80.03\;g\;of\;NH_4NO_3}=0.57\;moles\;of\;NH_4NO_3

Now we can use this to determine how many moles of H2O this would produce by using the ration we solved for earlier.

0.57\;moles\;of\;NH_4NO_3\times\dfrac{2\;moles\;of\;H_{2}O}{1\;mole\;of\;NH_4NO_3} =1.14\;moles\;of\;H_{2}O

And we convert that by getting the molecular mass of H2O, which is 18.02 g/mole:

1.14\;moles\;of\;H_{2}O\times\dfrac{18.02\;g\;of\;H_{2}O}{1\;\;mole\;of\;H_{2}O} =20.54\;g\;of\;H_{2}O

But this is only if the whole 45.7 g of ammonium nitrate is used up.

Which statement explains why the bonds between non metals tend to be covalent
UNO [17]
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

What is the molar concentration (molarity) of a solution made by dissolving 0.285 moles of CaCl2(s) in just enough water to form
marusya05 [52]

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
