And you get this chemical reaction and it looks like lava. So we’re gonna leave that there for about an hour and then once it hardens we smash it into pieces and it’s ready to eat. If you mix ...

It is more obvious in reactions that do not go to completion that the reaction is reversible. This is the case when the reaction mixture contains both reactants and products.

Pour 50mL of 0.4M cobalt chloride solution into a beaker to demonstrate the color of the catalyst solution, then add it to the reaction mixture with stirring. Stand back! The reaction will be vigorous ...

Three colorless solutions are combined into a large beaker and the mixture becomes amber, then blue-black, and then colorless again. This sequence of color changes will repeat with a period of ...

The initial test with FM, read at D3, showed a ?+ reaction in 40 (29%) of the patients, a + reaction in 42 (30.4%) of the patients, a ++ reaction in 28 patients (20.3%), and a +++ reaction in 28 ...
