Chemistry - part of our lives, and without certain processes that occur on Earth before life began, of course, it would not be us. The assimilation of food, human and animal respiration is based on chemical reactions. The same process of photosynthesis, without which people can not live, is also accompanied by chemical processes.Few people think that ignites a match, that carries out this complicated chemical process. Or, for example, personal hygiene is also accompanied by chemical reactions when a person uses soap that foams in contact with water. The same wash using powders, conditioners for softening the laundry accompanied by such reactions.Even in ancient times were common craft, which were based on chemical processes: for example, the creation of ceramics, metal processing, the use of natural dyes.hus, the chemistry of life - this is a panacea for the disease, and weapons, and the economy, and cooking, and, of course, life itself.
Dear Mum and Dad I am writing you a letter as you asked me to. I can't believe I am staying in Paris for three weeks. Everything is so amazing! People are so kind here, they help me a lot, as I don't know French. My host family is so friendly! This family isn't very big: mother, father and two adorable sisters - Marie and Lucie They were asked me a lot about Russia and our life style. Last week I saw The Eiffel Tower and I loved it! Oh my God, it is so beautiful. I took a lot of photos but they can't capture this beauty. Also I visited Louvre. You know, this was my dream to be here. I still can't believe I was in this magical place. Marie, Lucie and I are going to Notre Dame. I can't wait to see it! As you can see, I am very happy to be in France and I so thankful to you that you let me go there. Sending lots of love! Yours,...
