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:

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.  

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
