The chemical equation below shows the decomposition of ammonium nitrate (nh4no3).

nh4no3 -> n2o + 2h2o

a chemist who is performing this reaction starts with 160.1 g of nh4no3. the molar mass of nh4no3 is 80.03 g/mol; the molar mass of water (h2o) is 18.01 g/mol. what mass, in grams, of h2o is produced?

a)9.01
b)18.01
c)36.03
d)72.06

 The mass  in grams  of H₂O  is 72.04  grams  which  is  around (answer D)

Calculation

Step 1 :  calculate the moles of NH₄NO₃

moles  =  mass/molar  mass

 =160.1 g / 80.03  g /mol =  2 moles

Step  2: use the mole  ratio to calculate the  moles of H₂O

NH₄NO₃:H₂O  is 1:2  therefore the moles of H₂O  is  

= 2 moles x 2 = 4 moles

Step 3: calculate the mass of  H₂O

mass = moles  x molar mass

= 4  moles  x 18.01 g/mo= 72.04 grams  approximate   (answer D)

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

i think the answer is terrae but not 100 percent sure. ▓▬▬ §
