The answer is 1. This is because electronegativity increases up a group and across a period. So metals are going to be the least electronegative. 4.0 is the most electronegative element on Paulina's Scale!
Answer:
Check the explanation
Explanation:
cell CuE Ecell 0.337 (-0.14) Ecl0.477 V
Since
, the value of \Delta G^o will be negative.

.....(1)
But
......(2)
From (1) and (2)

ln K =
ln K =
ln K =37.139
K =
Hence, the value of the equilibrium constant is 
The cost for CHOPS is in the sand and the extraction of the oil from sand.
The cost for SAGD is the generation of steam.
The benefit for CHOPS is the low cost.
The benefit for SAGD is high extraction efficiency.
The other factors that could affect the decision are fuel cost and the required purity of the oil.
Explanation:
Carbon dioxide dissolves in water and slowly reacts with water to produce carbonic acid. The cloudy white solution observed when CO2 is bubbled into limewater results from a reaction between Ca(OH)2 and either CO2 or H2CO3 to form an insoluble calcium carbonate precipitate.
