According to newtons law every action has a equal reaction therefore it will push back 200n aswell
Answer:
On contact with ice, calcium chloride forms brine rapidly, which lowers the freezing point of water and melts snow and ice quickly. Calcium chloride forms brine faster than other ice melters because its hygroscopic properties actually cause it to attract moisture from its surroundings

Make sure the results of the experiment are useful
Explanation:
In an experiment, certain variables (independent variables) are controlled to check how they affect other variables (dependent variables) and understand the relationship between them. Also, these experiments usually have a control experiment, of no change, to help compare results and increases their reliability.
What details? I need more information than that
Answer:
Chain reaction
Explanation:
A chain reaction is a reaction that sustains itself. It has the ability to continue for a very long time without adding any more materials to the reaction system. It may be succinctly described as a self propagating reaction.
In a nuclear fission, uranium-235 is bombarded with neutrons to produce unstable uranium-236 which disintegrates to form daughter nuclei and produce more neutrons that bombard more uranium-235 and the reaction continues indefinitely.
