What is homeostasis? The maintenance of a constant internal environment. What is a stimulus? A change in your environment than requires a response. e.g Light, sound, touch, pressure, pain, chemical or temperature. What do the receptors do? Detect the stimulus or change in environment. What happens after the receptors? Receptors send messages to the CNS via the sensory neurone. What makes up the central nervous system? The brain or spinal cord What is an effector? Muscles or glands tha...

Detailed and comprehensive notes on unit 3.2.5 (transition metals) of AQA A level chemistry. Covers: transition metal properties/trends, complex ions, substitution reactions, coloured ions, variable oxidation states and catalysts. Includes key equations and observations to learn.

AQA Chemistry; Transition Metals Final Test 2023.In what block are the transition metals found? - ANSWER D-block What is the definition of a transition metal? - ANSWER A transition metal is a metal that can form one or more stable ions with an incomplete D sub-level How many electrons can fit into the d sub-level? - ANSWER 10 What transition metals have a different electronic configuration? - ANSWER Chromium and copper How does the electronic configuration of chromium differ? - ANSWE...

Experiment for Diffusion? - Correct Answer 1) HCl placed at one end of the test tube, ammonia solution at the other. 2) Where they meet, a ring of Ammonium Chloride appears. 3) The diagram shows that the ammonia is closer to the ring, showing that ammonia must have travelled faster, showing it's a lighter gas. Experiment for Dilution? - Correct Answer 1) Put a coloured substance in a solvent e.g food colouring in water. 2) Over the time, the colour levels out but is weaker than the origi...
