Ответ:

Активнее всего реагирует Калий, так как является щелочным металлом и более активен, чем Натрий, который также является щелочным металлом, поскольку находится ниже Натрия в периодической системе.

Объяснение:

Ca является щелочно-земельным металлом и будет реагировать менее активно. Магний с водой в реакцию не вступает.

Алюминий при реакции с водой покрывается защитной пленкой и будет реагировать лишь после ее удаления.

Помогите перевести текст. (я искала в интернете, но тот текст несколько отличается от этого)
A merry group of friends was sitting on a restaurant terrace. The table was laid for four: two men and two women. The waiter was sent for and soon dinner was served. Everyone was eating fish, and when the dinner was finished, a woman said, "Diamonds and pearls are often found inside fish." A lot of interestingstories were told until an old gentleman, who had been sitting quietly all the time, said, "I'll tell you a story about fish." Everyone agreed, so the old gentlemancontinued, "When I was a young man, I worked in a large company in New York. At that time I was in love with a pretty girl. Very soon we were engaged. About two months before our wedding I had been suddenly sent to England. I promised to write to my girlfriend because I had to stay in England longer than I hadplanned and I was very upset.

Finally, my work was done and I could go home. I was very happy because I had bought a very expensive diamond ring for my future wife.

On my way to New York I was looking through the morning newspaper, which had been brought to me by the waiter. In the newspaper it was written that my girl was going to marry another man.

This made me so angry that I threw the ring into the sea.

A few days later when I was in a restaurant in New York, some fish was brought to the table. While I was eating, I felt something hard in my mouth. What do you think it was?"

"The diamond ring!" cried the friends. "No," said the old gentleman, "it was a fishbone."
