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.

coral.

explanation:

coral. many marine organisms that produce calcium carbonate shells or skeletons are negatively impacted by increasing co2 levels and decreasing ph in seawater.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
