<prompt> Fana ka mohlala oa phetoho ea likhemikhale e etsahalang letsatsi le letsatsi.nan  <response>: Instruction in English: Give an example of a chemical change that occurs everyday. . Response in English: An example of a chemical change that occurs every day is the process of rusting. When iron or steel is exposed to oxygen and moisture, a redox reaction occurs, forming iron oxide or rust. This is an everyday chemical change because it is constantly happening in our environment, especially in humid areas or regions near the ocean. The rusting process is a chemical change because the iron atoms react with oxygen atoms to form a new compound, iron oxide, which has different properties than the original iron or steel. . Response in Sesotho: Mohlala oa phetoho ea likhemikhale e etsahalang letsatsi le leng le le leng ke mokhoa oa ho rusa. Ha tšepe kapa tšepe e pepesehetse oksijene le mongobo, ho ba le karabelo ea redox, e etsang iron oxide kapa mafome. Ena ke phetoho ea letsatsi le letsatsi ea likhemikhale hobane e lula e etsahala tikolohong ea rona, haholo-holo libakeng tse mongobo kapa libakeng tse haufi le leoatle. Mokhoa oa ho rusa ke phetoho ea likhemikhale hobane liathomo tsa tšepe li kopana le liathomo tsa oksijene ho etsa motsoako o mocha, oa iron oxide, o nang le litšobotsi tse fapaneng le tsa tšepe kapa tšepe ea pele.
