If you hit iodine with a hammer, it will likely shatter into smaller pieces due to its brittle nature. However, iodine sublimes easily from a solid to a gas at room temperature, so some of the iodine may also turn into vapor upon impact.
If you were to hit iodine with a hammer, it would most likely shatter into small pieces or powder. Iodine is a brittle solid, and its crystal structure would break upon impact from the hammer.
A copper rod will deform and flatten out when struck with a hammer due to its malleability. The force of the hammer will cause the copper atoms to shift and slide past each other, resulting in a change in shape.
If iodine solution is added to a leaf, it will turn blue-black in color. This is due to the presence of starch in the leaf which reacts with iodine to produce this color change.
The iodine will turn blue-black in the presence of starch due to the formation of a complex known as "iodine-starch complex." This color change is often used as a test for the presence of starch in a sample.
The iodine solution in the baggie would diffuse into the beaker containing the starch. The iodine molecules would interact with the starch molecules, resulting in the formation of a dark blue or black color, indicating the presence of a starch-iodine complex.
