This pack contains all of the flashcard I made myself throughout the AS-level course
| Front | explain the trend in thermal stability of carobnates and nitrates? |
| Back | metal ions becmoe larger down teh group but their charge stays teh same so they have a decreasing charge density as we go down.a metal ion with high cahrge density has more polarising power so it can thereforce piolarize teh carbonate ion,making it more likely to split into O2- and CO2 when heated. |
| Front | what happens if we are square rooting uncertainties? |
| Back | we half the uncertainity |
| Front | what do precise measurements have that can be a bad thing? |
| Back | small random errors that are reproducible in repeated trials |
