Answer:
Al2(SO3)3 + K3PO4
Explanation:
I believe this is an example of double replacement and also, the equation needs to be balanced with the amount of each atom per side.
<u>Answer:</u> The change in entropy for the system is 140.3 J/K
<u>Explanation:</u>
The chemical equation follows:
To calculate the entropy change for vaporization of methanol, we use the equation:
where,
= entropy change of the reaction
n = number of moles = 1.00 mole
= heat of vaporization = 35.21 kJ/mol = 35210 J/mol (Conversion factor: 1 kJ = 1000 J)
T = temperature of the system =
Putting values in above equation, we get:
Hence, the change in entropy for the system is 140.3 J/K
The dissociation of formic acid is:
The acid dissociation constant of formic acid, is:
Rearranging the equation:
pH = 2.75
Substituting the values in the equation:
Hence, the ratio is .
