Axel Fredrik CronstedtDied 19 Aug 1765 at age 42 (born 23 Dec 1722). Swedish chemist and metallurgist who was the first to isolate nickel (1751) and notice its slight magnetic properties. A new chemical classification of minerals he made was translated to several languages. Patterns he found in the internal structure of minerals enabled him to distinguish between simple one-compound minerals and those comprised of a mixture of several minerals. He discovered zeolite, a water-softening silicate and analysed the high-density mineral calcium tungstate. By adept use of the blowpipe to intensify a flame and burn a small quantity of a mineral he could make an identification of its chemical composition based on the colouring of the flame. He did not invent the instrument, but founded systematic blowpipe analysis technique.« |
MAGIC SQUARE: Calculate A+B*C
The aim is to place the some numbers from the list (15, 16, 17, 25, 26, 27, 33, 54, 55, 56, 61) into the empty squares and squares marked with A, B an C. Sum of each row and column should be equal. All the numbers of the magic square must be different. Find values for A, B, and C. Solution is A+B*C.The first user who solved this task is Nílton Corrêa de Sousa.
