#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 :(

#2: Which of the following is the balanced form of the equation C2H6 + O2 --> CO2 + H2O? answer choices attached A,B,C,D top to bottom :) **my answer; D is that right?
what do they mean by activity? nothing would happen because Au is not reactive (too stable, and highly difficult to oxidize)
#3: The equation 2NaNO3 + CaCl2 ---> 2NaCl + Ca(NO3)2 is balanced. How many atoms of sodium (Na) are there on either side of the equation? A. one B. two C. four D. six **my answer: B. two is that right?

Other answers:

2 and 3 are right
#4: All single-displacement reactions can be classified as another type of reaction as well. What type of reaction is that? A. combustion B. redox C. synthesis D. decomposition **ugh.. im bad with definitions haha :P idk is it B. redox or D. decomposition?? idk this one :(
#5: If ions change places and a gas is formed, then what type of reaction is indicated? A. double-displacement B. synthesis C. decomposition d. single-displacement **not too sure.. I'm debating b/w A and C... what do u think?
wait so what's #1?? idk like they mean reactions by activity... i think... haha :P
and yay for 2 and 3!! :D and so #4 is B. redox ??
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
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?
so #5 is decomposition??
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
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
i looked up on google and a few of them said it had lower activity
so go with B
umm well theres nothing in my book :( and okay then :) thanks!! :D hopefully its right!! :D
hope so!
crossing my fingers :D
