One of the intermediates in the synthesis of glycine from ammonia, carbon dioxide, and methane is aminoacetonitrile, C2H4N2.
How much C2H4N2 could be expected from the reaction of 14.9 g CO2, 2.11 g NH3, and 1.75 g CH4?

Explanation:

You must start by stating the chemical equation for the reaction of ammonia, carbon dioxide, and methane to produce aminoaceto nitrile.

1. Word equation:

Ammonia + Carbon dioxide + Methane → Aminoacetonitrile + Water

2. Balanced chemical equation:

3. Convert the mass of each reactant into number of moles:

Formula:

2.11g NH₃

14.9g CO₂

1.75g CH₄

4. Theoretical mol ratio

From the balanced chemical equation, using the coefficientes:

5. Limiting reagent

The available amounts of the reactants are:

Fom the theoretical mole ration, to react with 0.124 mol of NH₃ you would need:

Since there are 0.339 moles available, this is in excess.

Since there are 0.109 moles available, this is in excess too.

Hence, the limiting reagent is NH₃.

6. Yield

Use the theoretical ratio:

Convert to grams:

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
