If 45 moles of NH3 and 50 moles of NO2 react, which one is the limiting reactant ? 8 NH3 (g) + 6 NO2 --> 7 N2 (g) +12 H2O (g)

NH₃ is limiting reactant .

Explanation:

Given data:

Number of moles of NH₃ = 45 mol

Number of moles of NO₂ = 50 mol

Limiting reactant  = ?

Solution:

Chemical equation:

8NH₃ + 6NO₂        →      7N₂  + 12H₂O

Now we will compare the mole of reactants with products.

               NH₃           ;          N₂

                 8              :          7

               45              :        7/8×45 = 39.4 mol

                NH₃           ;         H₂O

                 8              :          12

               45              :        12/8×45 = 67.5 mol

               NO₂           ;          N₂

                 6              :          7

               50              :        7/6×50 = 58.3 mol

               NO₂           ;         H₂O

                 6              :          12

               50              :        12/6×50 = 100 mol

Less number of moles of product are formed by the ammonia thus it will be limiting reactant.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
