Answer the following questions related to stoichiometry. Each question should be answered thoughtfully, providing the necessary calculations and explanations where required.
Define stoichiometry. Why is it important in chemical reactions?
In your answer, discuss the concept of mole ratios and how they relate to the conservation of mass.
Given the balanced chemical equation:
2 H₂ + O₂ → 2 H₂O
How many moles of water (H₂O) can be produced from 4 moles of hydrogen (H₂)?
Show your calculations and explain the steps taken to arrive at your answer.
*Calculate the mass of NaCl produced when 3 moles of Na react with chlorine gas (Cl₂) according to the following balanced equation:
2 Na + Cl₂ → 2 NaCl
(Molar mass of Na = 23 g/mol, Cl = 35.5 g/mol)
Provide your calculations clearly, indicating the steps involved in solving the problem.
If 5 moles of Reactant A produce 3 moles of Product B according to the reaction:
A → B,
how many moles of A are required to produce 12 moles of B?
List your calculations and reasoning in your answer.
Identify the limiting reactant in the chemical reaction:
3 H₂ + N₂ → 2 NH₃,
when starting with 4 moles of H₂ and 1 mole of N₂. Explain how you determined the limiting reactant.
Include calculations for determining the amounts of products formed from each reactant.
