IB skill practice

Balance equations and use mole ratios

Paper 1, Paper 2 5 marks Difficulty 3

Calculate product moles from ratio

For N2 + 3H2 -> 2NH3 in a industrial ammonia discussion, \(2\,\text{mol}\) of N2 reacts completely. Calculate moles of NH3 formed. Enter the answer and choose the interpretation that matches the chemistry.

Worked practice: chemistry evidence and answer

Use the chemical evidence first, then enter the result and interpretation that match it.
