Need help with my work chemistry assignment grade 12 college work please

A)0.450 mol N2

B)294 g NH4 NO3

Explanation:Step by step! make sure when you see underneath the multipication eqaution that we are deviding!The arrows is what we are dividing

A)36.0gN H4N O3×1 molN H4NO3×2mol N2

        ↑ 1                   ↑ 80.05gNH4NO3 ↑2mol N H4N O3

B)7.35molH2O×2mol N H4 N O3×80.05gN H4 N O3

    ↑    1                 ↑  4molH2O             ↑   1mol N H4N O3

5) 2 and for the how many moles it is 10.9

Hope this helps!

yes it is balanced

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
