Group Title
#1: The following reaction does not proceed to form a product: H2O + Au> no reaction. Why is that?
A. Gold has a higher activity than hydrogen and cannot replace it.
B. Gold has a lower activity than hydrogen and cannot replace it.
C. The reaction cannot occur because water is a reactant.
D. The reaction proceeds too slowly to create products.
**my answer; B
im not too sure on this one tho :(

what do they mean by activity? nothing would happen because Au is not reactive (too stable, and highly difficult to oxidize)

and yay for 2 and 3!! :D and so #4 is B. redox ??

aaronq Group TitleBest ResponseYou've already chosen the best response.1
yep 4 is redox, 1 I'm not sure, as i don't know what they mean by "activity", I've never seen that used in that fashion

yeah idk :( that was one i was kinda confused on.. well more confused that the others haha :P and what do u think bout #5?

and so u don't get #1 at all?? :/

5 maybe decomposition

aaronq Group TitleBest ResponseYou've already chosen the best response.1
for 1 i can't answer, because I've never heard of this "activity", there is a term activity but its not used in this context

ohh okay :/ I'm thinking activity means like chemical reactions,... thats how it was used b4... :/ does that help?

iheartfood Group TitleBest ResponseYou've already chosen the best response.0
so #5 is decomposition??

aaronq Group TitleBest ResponseYou've already chosen the best response.1
yep i mean i would say it's both, but you don't always form a gas in a double displacement, but you don't always double displace in a decomposition... :S

aaronq Group TitleBest ResponseYou've already chosen the best response.1
but go with decomposition

ohhh okay :) so for #1, i should just wing it?? haha :/

unless you have an example somewhere in your books/notes you can look at and compare

aaronq Group TitleBest ResponseYou've already chosen the best response.1
i looked up on google and a few of them said it had lower activity

aaronq Group TitleBest ResponseYou've already chosen the best response.1
so go with B
