| Metal Reaction Examples in Revision Guide | aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa |
| What is Oxidation? | Loss of Electrons or sometimes Gain of Oxygen |
| What is Reduction? | Gain of Electrons or sometimes Loss of Oxygen |
| What is a Redox Reaction? | A reaction where Oxidation and Reduction happen Simultaneously |
| What happens in a Displacement Reaction? | A More Reactive Element reacts to take the place of a Less Reactive Element in a compound. |
| True / False Metals More Reactive than Carbon can be Extracted by Reduction with Carbon? | False Metals that are Less Reactive can |
| What Extraction Method is used for Metals More Reactive than Carbon? | Electrolysis |
| Is Reduction with Carbon or Electrolysis more Expensive for the Extraction of Metals? | Electrolysis |
| idk how to make a question out of recycling so remember to recycle kids | yeah |
| What is a Reversible Reaction? | A reaction that can go both forwards and backwards |
| Without a change in Pressure or Temperature, how do Reversible Reactions reach an Equilibrium | Forward Reaction's concentration falls as Backward Reaction's concentration rises. Eventually they will be exactly at the same rate. This is equilibrium. Both reactions are both happening, but there's no overall effect |
| How can an Equilibrium lie to the Right / Left? | The concentration of the products / reactants is greater than the concentration of the reactants / products. |
| What 3 Things can Change the Position of Equilibrium? | 1. Temperature 2. Pressure 3. Concentrations |
| What is Le Chatelier's Principle? | If there's a change in concentration, pressure or temperature in a reversible reaction, the equilibrium position will move to help counteract the change |
| What does Changing the Temperature in a Reversible Reaction do to the Equilibrium? | Decreasing - Exothermic Direction - Produce more heat Increasing - Endothermic Direction - Absorb extra heat |
| What does Changing the Pressure in a Reversible Reaction do to the Equilibrium? | Decreasing - More moles of gas - Increase pressure Increasing - Less moles of gas - Decrease pressure |
| What does Changing the Concentration in a Reversible Reaction do to the Equilibrium? | Increase - Opposite side (more products / reactants) Decrease - Towards same side |
