The answer is (3). The reaction that can occur at the anode is oxidation reaction which will lose electrons. So (1) and (2) are not correct. For (4) Fe3+ can not lose electrons again.
From the combined gas law
that is P1V1/T1=P2V2/T2
P2 is therefore T2P1V1/TIV2
A gas at STP has a temperature of 273k and a pressure of 760torr
P1=760torr
T1=273K
V1=6ml
P2=?
T2=525+273=798K
V2=500ml
P2 ={(798k x760 torr x 6ml) /(273k x500ml)} = 26.7 torr
Answer:
it should be B. earths core is composed of iron and nickel, if not let me know.
Explanation:
K2O Now the cation is the element at the front so it would be K2 because the 2 belongs with the K which is Potassium and now Anion is the last element O for oxygen
