How did it get to that state? Let's assume that we started with \(A\) and \(B\). This is the equation for a general reaction which has reached dynamic equilibrium: However, the overall numbers of orange and of blue squares remain remarkably constant - most commonly, 12 orange ones to 4 blue ones. The exact pattern of orange and blue is constantly changing. You can see that the "reaction" is continuing all the time. The diagrams show the results of doing this 11 times (plus the original 16 blue squares). Once I had looked at all 16 squares, I started the process all over again - but obviously with a different starting pattern.
An orange square was turned into a blue square only if I threw a 6 while I was looking at that particular square.A blue square was turned into an orange square (the bit of paper was turned over!) if I threw a 4, 5 or 6.Started with 16 blue squares and looked at each one in turn and decided whether it should change colour by throwing a dice. The following are the real results of a "reaction". You can simulate this very easily with some coloured paper cut up into small pieces (a different colour on each side), and a dice. In any given time, these are the chances of the two changes happening: Assume that the blue form turns into the orange one much faster than the other way round. We are going to let them react in a closed system neither form can escape. Manufactured in Germany for Thames & Kosmos in the United States.Imagine a substance which can exist in two forms - a blue form or an orange form - and that each form can react to give the other one.
Since December 19 2013, these products have been sold in Canada for at least five years. Neither Health Canada, nor Filosofia, nor Thames & Kosmos have received any reports of incidents or injuries to Canadians related to the use of these products. Inclusion of prohibited substances and a lack of required labelling can both lead to serious adverse health effects. In addition, it has been identified that the C2000, C3000, and the Spectacular Science experiment kits contain prohibited substances under the Canada Consumer Product Safety Act and its Regulations. These labels direct the user to important safety information regarding use of the chemicals provided with the product and communicate recommended age suitability for use of the products. It has been identified that the C500 and C1000 experiment kits contain hazardous chemicals and have been sold in Canada without the required safety warning statements and labels. versions of the kits that are being recalled."
