Ответ:

2HCl + Ba = BaCl2 + H2

HCl + NaOH = NaCl+ H20

2HCl + MgO = MgCl2 + H20

2HCl + K2CO3 = 2KCl + H20 + CO2

Можите составить маленькиq пересказ на англ.яз. 

 

 

Russia has produced (1) a singer, who, according to (2) music critics and cultural experts, is going to decide (3) the direction of Russian music. Pelageya Khanova, 17, has (4) a remarkable voice that covers three and a half octaves. Musically, she can do everything, including acoustic, electronic and folk music. She also recorded a song called Home for the Depesha dlya Depeche Mode tribute album and sang • the famous Mary Magdalene aria from Jesus Christ Superstar.
Apart from that she is a person with unique abilities — when she was only three and a half years old she wrote short stories and typed them up on a typewriter; she also finished school earlier than other students, Although this charming and lively teenager has sung for presidents, first ladies, and other celebrities, she says all her listeners are equally important to her, whoever they are. She insists she has never been influenced by her fame — "I go clubbing, go to the movies — I'm just like any other girl of my age and I like it!"  .
She sees her goal in life as reviving folk music. Pelageya has a real interest in singing folk because she finds hundreds of profound messages in them. She wants to explode the kitschy image of folk music — peasant women, bears and balalaikas — that both Russians and foreigners may have.
