5short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.
What are limiting reactant problems with gases?Show answer
When two reactants are given (one or both gases), determine the limiting reactant first.
What are percent yield with gases?Show answer
Percent yield = (actual yield / theoretical yield) x 100 percent. Express both yields in the same units (both as volume, both as mass, or both as moles).
What is q1?Show answer
State the molar volume of an ideal gas at SLC and at STP. [2 marks]
What is q2?Show answer
Calculate the volume of produced at SLC when Mg reacts with excess HCl. [4 marks]
What is q3?Show answer
Ammonia is synthesised by . Starting with and at SLC: (a) Identify limiting reagent. (b) Calculate .
