Answer 3

What's your best guess?

Answer 4

Also, why is that your guess? Electronegativities? Magic? Why?

Answer 5

My best guess would be D.

Answer 6

Considering it starts with water, I think it's likely that the product isn't going to be water. That would likely be what happens if there wasn't a reaction. But I think that might result in making Sulfuric Acid.

Answer 7

i think Cu(OH)2+ H2S---> CuS+2 H2O
