A bag contains red counters and blue counters. Two counters are taken from the bag at random, without replacement.

Calcium carbonate decomposes when heated:
Calculate the mass of carbon dioxide produced when of calcium carbonate decomposes completely.

Questions are written for DiplomaHub in the style of IB papers. DiplomaHub is not affiliated with the International Baccalaureate.
Pick any of your subjects and topics, then answer on screen or on paper. Each question is marked against the markscheme's points.
Every finished set updates your strength map, topic by topic, so you can see what's solid and what needs work.
Add tests and deadlines to the free Hub. Home counts down to the next one and suggests what to practise before it.
DiplomaBro reads your calendar and your strength map and tells you what to do first. Ask it to explain a question, check your working, or plan your week around your tests. If you want, it builds the study plan and puts the study blocks in your calendar for you.
Your Economics mock is on Thursday and elasticity is your shakiest topic, so start there tonight. Your Physics waves are slipping too: 20 minutes on Wednesday would help. Want me to block both into your calendar?
