Potassium and Chloride forms an ionic bond.
(K+) + (Cl-) = KCl
Potassium is under Group IA (Alkali Metal), wherein elements under this group can easily lose electrons.
Chlorine is under Group VII (Halogens), in which these elements can gain electrons easily.
The inner shell electrons on potassium will merge with the outer shell of electrons of chlorine to make potassium chloride.
Answer:
2
Explanation:
symbol of postassium is k and there is no symbol k. so i guess no2
Answer:
the overall reaction is
P4(s) + 10Cl2(g) => 4PCl5(g)
and its ΔH is
ΔH overall = (-1608 KJ)
Explanation:
given that
P4(s) + 6Cl2(g) => 4PCl3(g) , ΔH1 = –1148 kJ
4PCl3(g) + 4Cl2(g) => 4PCl5(g) , ΔH2 =–460 kJ
summing both equation gives
P4(s) + 6Cl2(g) +4PCl3(g) + 4Cl2(g) => 4PCl3(g) + 4PCl5(g)
but 4PCl3(g) is in both sides , so is cancelled out
P4(s) + 6Cl2(g)+ 4Cl2(g) => 4PCl5(g)
summing the Cl2(g)
P4(s) + 10Cl2(g) => 4PCl5(g) → overall reaction
(can be verified that the reaction is balanced)
since we sum both equations the ΔH of the overall reaction is also the sum of the ΔH of the individual reactions.
ΔH overall = ΔH1 + ΔH2 = (–1148 kJ) + (–460 kJ) = (-1608 KJ)
Answer:
Argon
Explanation:
The element that would most likely be a good substitute for neon is "argon".
These two elements belong to the noble gases in Group 18(8A) of the Periodic Table. They are inert gases - they do not react chemically with other substances.
Argon, as an inert gas is often used whenever an inert atmosphere is needed. Argon is used in incandescent light bulbs. It is used to stop oxygen from corroding the filament. It is also used by welders to protect weld area.
Argon is a good substitute for neon in this context because they possess some physical properties which are similar.
