Hypothesis when h2o2 and a catalyst are mixed together, the catalyst would break down h2o2 into water and oxygen. At the anode i think that chlorine will be produced due to the half equation 2cl -2e àcl the chlorine ions are negative so they are attracted to the positive electrode. How does the changing of the current and surrounding temperature effect the electrodes.

Cao analysis in order to determine the enthalpy change for the thermal decomposition of calcium carbonate, we must work out the enthalpy changes for both the reactions of calcium carbonate and calcium oxide with hydrochloric acid. Papers investigating which metal combination gives out the most voltage in a solution - investigating which metal combination gives out the most voltage in a solution background metals are an order of chemical elements in the periodic table. I think this because the higher the concentration, the more atoms there are, then there are more chickens and therefore there are more collisions as a direct result of the concentration.

Papers - finding the change in the mass of the electrodes during electrolysis safety before carrying out he investigation we had to take safety into consideration so we wore goggles to protect our eyes from any harmful chemical and aprons to protect our clothes from anything that may get spilt. I think this because the higher the concentration, the more atoms there are, then there are more chickens and therefore there are more collisions as a direct result of the concentration. From the equations above we can see that in both reactions gas is evolved and by collecting the volume of gas produced we can accurately say which reaction is taking place.

It is of little consequence what acid is used however in this case i will use sulphuric acid (h2so4). Several factors affect the resistance temperature length cross-section area the metal or alloy the conductor is made of this investigation looks at the effect of length. Papers - investigating the factors that affect the resistance of a metal conductor all metals offer some resistance to the flow of an electric current.

For caco3 temperature change 2c to find the enthalpy change of a reaction, we must first work out the amount of energy taken in by the reaction. All of them are solid (apart from mercury), good thermal and electrical conductors and are shiny when polished. Thermal decomposition is the breakdown of a substance using thermal energy, this is not a reaction.
