Ответ:

4Al + 3O2 = 2Al2O3

Al2O3 + 6HCl =2 AlCl3 + 3H2O

AlCl3 + 3NaOH = Al(OH)3 + 3NaCl

Al(+3) + 3Cl(-) + 3Na(+) + 3OH(-) = Al(OH)3 + 3Na(+) + 3Cl(-)

Al(+3) + 3OH(-) = Al(OH)3

Al(OH)3 + 3HNO3 = Al(NO3)3 + 3H2O

ДОПОЛНИТЕЛЬНЫЙ МАТЕРИАЛ К УРОКУ I My household duties I live in a family, which consists of father, mother and me. Everyone in our family has his duties at home. And, of course, I have my duties too. I like to help my parents, and it is not difficult for me. Every Sunday I clean my room. I begin with the cleaning of carpets. I usually take a vacuum cleaner and turn it on and then clean. Then it comes the turn to sweep the floor, to dust the furniture. I try to do this work in a proper way. Besides, one of my duties is to water the flowers. I do it twice a week. We have a lot of flowers in our flat and all of us like them very much. Besides, my duties include some kind of shopping. I usually go to the shop to buy bread, milk and some other food. It is not difficult for me because the shop is near our house. I think that there is nothing bad in helping parents. I under- stand my parents quite well, because they are too busy at work. My parents also try to understand me and allow me to go to night clubs with my friends and to invite my friends to our place. We are a happy, friendly family.
