Explanation:
Limiting reagent is the reagent which limits the formation of product. Excess reagent is one which is in excess and thus remains unreacted.
Thus lithium is the limiting reagent and nitrogen is the excess reagent.
As can be seen from the balanced chemical equation, 6 moles of lithium reacts with 1 mole of nitrogen to give 2 moles of lithium nitride.
Thus 0.578 moles of lithium react with 0.096 moles of nitrogen.
6 moles of lithium give = 2 moles of lithium nitride
Thus 0.578 moles of lithium give= of lithium nitride.
Mass of lithium nitride
Mass of lithium nitride=
Answer:
Explanation:
Isomerism is the occurrence of two or more compounds with the same molecular formula but different structures. Isomers with the same molecular formula and belonging to the same homologous series tends to have similar chemical properties but slightly different physical properties as a result of their constitutional (structural differences).
Thus,as the number of carbon atoms in a molecule increases , the number of isomer also increases. In the given question C7H16 is known as heptane which have nine (9) possible constitutional (structural) isomers.
The main objective is to provide the names for the constitutional isomers with the molecular formula C7H16.
In the attached file below; we've shown the possible isomers of heptane (C7H16). and we've identify them by naming them.
