It works through how to solve the problem by getting rid of the indigestion through a neutralisation reaction. It uses vinegar to represent stomach acid and they have to determine which of the substance to use to get rid of the person's indigestion.

Reactions	https://www.youtube.com/watch?v=2dbq0KJ-HRw	Thermal decomposition of metal carbonates	This video discusses thermal decomposition of a metal carbonate. It starts off by going through a diagram of the equipment and the expected result of limewater going cloudy/milky.  It defines the term and goes through the general equation for the reaction.

Reactions	https://www.youtube.com/watch?v=_wzJQFl1k9I	Products of combustion of fuels	This video discusses what happens when a candle is burnt. It identifies the products when a hydrocarbon is burnt as water and carbon dioxide. They prove this by collecting the gases produced by having a cooled test tube to collect any water vapour and use limewater to test whether carbon dioxide is produced.	Demo	FALSE

Reactions	https://www.youtube.com/watch?v=epDGHnwaVJY	Burning Magnesium	This video discusses the reaction of magnesium in oxygen to form magnesium oxide. It shows the symbol equation for the reaction and explains heat is required for the reaction to occur. They then demonstrate this reaction showing magnesium being burnt and then a white powder of magnesium oxide at the end.	Demo	FALSE

Reactions	https://www.youtube.com/watch?v=hFaxkBYuH2o	Reaction of Iron and Sulfur	This video demonstrates the reaction of iron and sulfur. It starts off by showing that iron is magnetic and sulfur is not. They then mix them together and both elements keep their properties. They then heat this mixture together forming iron sulfide, which is shown to be non-magnetic.	Demo	FALSE

Reactions	https://www.youtube.com/watch?v=Wwmsy4huZQ0	Conservation of mass 	This video discusses the law of conservation of mass. It starts off by defining the law of conservation. Then they get the starting materials needed for their reaction and weigh them to determine their mass. They then mix the chemicals and a precipitate forms showing a reaction has taken place. They then show that the mass of the products is the same as the reactants by re-weighing it.	Demo	FALSE

Reactions	https://www.youtube.com/watch?v=BTDRtSGNMtM	Exothermic and endothermic reactions	This video shows the an exothermic reaction and an endothermic reaction. The initial reaction is between vinegar and baking soda. The temperature of the reaction decreases so is endothermic. The second reaction is between vinegar and steel wool. The temperature of this reaction increase so is exothermic.	Demo	FALSE

Reactions	https://www.youtube.com/watch?v=EDUwc953GOA	Thermite reaction	This video discusses the thermite reaction. It starts by explaining that the reaction is a displacement reaction and aluminium, which is higher in the reactivity series, displaces the iron. The reaction is then shown in the video, highlighting the need for accuracy in the masses and thorough mixing. They prove iron has been formed using a magnet.	Demo	FALSE

Periodic Table	https://www.youtube.com/watch?v=m55kgyApYrY	Alkali metals with water	This video shows the reactions of group 1 (alkaline metals) with water. It starts off by briefly shows the reactions of lithium, sodium and potassium with water. It then goes on to discuss the fact the next two are extremely reactive and not completed within the lab.

It starts by showing the set up of distillation of inky water. They explain that water goes into the condenser at the bottom and out at the top which cools down the steam and condenses it. It shows the solution being heated and bubbling, evaporating into steam then condensing and falling into the second flask. Shows that the water coming out isn't coloured therefore separation has occurred.	Demo	FALSE
