Zn+CuSO₄ = Cu + ZnSO₄
Реакция замещения происходит между простым веществом и сложным. Атомы простого вещества замещают атомы в сложном веществе, вытесняя их. В данном примере цинк заместил атомы меди, стал на их место, а атомы цинка образовали простое вещество - цинк.

помогите соч
Harry: Hey, Elizabeth, how would you like to go see a movie tonight?
Elizabeth: Sounds great! What would you like to see?
Harry: I don't know... how about that new horror movie at the Arlington Theater?
Elizabeth: Oh, I heard about that. It sounds a little scary to me. I'm more into romantic movies. Or maybe a romantic comedy.
Harry: No way! I hate that kind of stuff!
Elizabeth: Really? Well then, what kinds of movies do you like?
Harry: I guess I'm really into action and adventure type of movies.
Elizabeth: Oh yeah, well I guess they are okay, as long as they aren't too bloody. I also heard about this great new musical that just came out. What do you think about that?
Harry: Musical? I don't know. That doesn't sound too exciting. Is there anything we can agree on?
Elizabeth: It doesn't seem like it. Oh, I remember another movie that came out last week. It's a mystery and it had a little romance and some action, too.
I heard it's pretty exciting because nobody can guess who the killer is and it has a surprise ending. What do you think about that one?
Harry: I guess that doesn't sound too bad. What time does it start?
