True. I think it's true but I could be wrong
Answer:
the standard cell potential value
Explanation:
For every cell, we can calculate its standard electrode potential from the table of standard electrode potentials listed in many textbooks.
However, from Nernst's equation;
Ecell= E°cell - 0.0592/n log Q
Hence the standard cell potential (E°cell) affects the value of the calculated cell potential Ecell from Nernst's equation as stated above.
Answer:
31.36 KJ/mol
Explanation:
mass of the liquid = 74.0 g
heat of vaporization = 21.40 kJ/mol
constant boiling point temperature = 24.09 °C
heat required to vaporize 74.0g = heat of vaporization × mole
mole of Chloromethane = 74.0 g / 50.49 (g/mol) = 1.466 mol
energy required = 1.466 mol × 21.40 KJ/mol = 31.36 KJ/mol
Answer:
2KI → 2K + I₂
Explanation:
(not my definition, but form a trustworthy source)
The definition of a decomposition reaction is:
a chemical reaction in which one reactant breaks down into two or more products.
In this case, potassium iodide will decompose into potassium and iodine.
2KI → 2K + 2I
2 Potassium and 2 Iodine on both sides, so equation is balanced.
Or, it can be written as 2KI → 2K + I₂
