I’m so sorry i have to do this 5L 24
With standard pressure there is a set list of values. (at STP), most common is 760torr. So whenever you see "at STP" or "at standard temperature pressure" you will use 760torr for pressure. Same thing goes with temperature, if you're not given temp and it says at STP you will use 273K.
For this problem:
You will be using the combined gas law:
(Pressure 1) x (Volume 1) / (Temp. 1) = (Pressure 2) x (Volume 2) / (Temp. 2)
(760torr) x (5.63L) / (287K) = (?) (9.21L) / (287K)
Pressure 2 = 465torr
*Hope this clarifies STP for you! :)
Answer:
they are single cells that lack a nucleus and tend to live in extreme conditions.- B.
Lithium sulfide (Li2S) would have 2 lithium atoms for every sulfur atom and would form an ionic bond. Sodium oxide (Na2O) has 2 sodium atoms for every oxygen atom (same ratio) and forms an ionic bond.
A solution is uniform throughout, so your answer is the first one.
