…I hope you have enjoyed in trying to get the right answer/s (as I imagined it in my head 😉 ) from the first task, the first quiz in this small Science Art association game. Before I disclose the answer/s on the first quiz problem, I will offer you the second assignment, the second problem for you to solve.
For all of you that are so eager to read the answer/s and explanations of the first quiz (before you try to solve this one), you can skip this first part of the post and read them at the end of this page.
For all of you who wants to play with me, to make things clearer, I suggest you to read the rules of this game at the beginning of the post cIQuiz… – Let´s Play the SciArT Game!
Now let´s begin with the second task (and this one is going to be a tough nut to break)!
Data/image resources obtained from the:
ANSWERS TO cIQuiz I…
COMMON TERM was
CORRECT ANSWERS were
B) Goethite (α-Fe3+O(OH)), D) Limonite ((Fe,O,OH,H2O)), F) Wüstite (FeO) (i.e. all the minerals that are iron oxides in chemical composition)
INCCORECT ANSWERS were
A) Cubanite (CuFe2S3), C) Lawrencite ((Fe2+,Ni)Cl2), E) Pyrite (FeS2)
EXPLANATIONS OF THE FINAL ANSWER…
The first image in the first quiz was showing the surface of the planet Mars. As some of you are maybe aware, the red surface of this planet is considered to come from the various minerals containing the metal iron, mostly in its many oxide forms.
Second image was showing the painting “Self-portrait”, made by famous Dutch painter Vincent van Gogh. Even do V. van Gogh was unknown in his own time (it is believed that he sold only one of his paintings in his whole life, “The Red Vineyard”), he became famous after his death, mostly because of his later works, that were made in many red, yellow and orange shades of color. Many people think he started to make paintings in this colors because he was suffering from chromesthesia, the color sickness, so he had problems with recognizing some colors (like Daltonism or color blindness). And in the art of painting; red, yellow and orange colors are obtainted from the (natural) pigments that contain iron oxides minerals.
