Focus on definitions.
Question 5.
A chemist mixes 2 moles of Na and 3 moles of Cl₂ for the reaction 2Na + Cl₂ → 2NaCl. How many moles of NaCl will be produced, and which is the limiting reactant?
Show hintHide hint
Use stoichiometric ratios based on the balanced equation.
Question 6.
In a reaction involving 1.5 moles of H₂ and 0.75 moles of O₂ to produce water (2H₂ + O₂ → 2H₂O), how much water can be produced, and which reactant is limiting?
Show hintHide hint
Step through converting moles of H₂ and O₂ to possible water production.
