wait do we have to know about atom economy?? I genuinely don't think we've been taught this in class
I'm genuinely so stressed for tomorrow, especially after seeing how alignment isn't great
nah hsc qs will give it to you as stimulus (at least they did in 2024)
good to have a rough idea of what it measures though

that question was so easy wdym?

c = n/v

since they rinsed it with acid, theres gonna be more moles of acid. this means concentration increases

My pred for last q: ”A polymerisation titration was conducted using chloroethene chlorinated using a chlorine solution whose concentration was firstly determined by conductometric back precipitation titration. If avg titre volume was 2mL (1sf btw), calculate the amount of Iron thiocyanate indicator added during the first titration. Then with reference to the mass spec provided and socioculturalenviroeconomic factors, evaluate this method’s effectiveness in modelling Aboriginal people’s understanding of saponification.” (12 marks)

if I saw this I'd genuinely cry.... I thought you were being serious at first
