The most reactive metal on the periodic table is Francium, However, Francium is an artificial element and only minimal quantities have been produced, so for all practical purposes, the most reactive metal available is Cesium, in the alkali metal family.
ANSWER In theory, Francium, in practice the Cesium
<u>Answer:</u> The mass of potassium sulfate that can be produced is 73.88 grams
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
.....(1)
- <u>For KOH:</u>
Given mass of KOH = 23.8 g
Molar mass of KOH = 56.1 g/mol
Putting values in equation 1, we get:
The chemical equation for the reaction of KOH and potassium hydrogen sulfate follows:
As, potassium hydrogen sulfate is present in excess. It is considered as an excess reagent.
KOH is considered as a limiting reagent because it limits the formation of product.
By Stoichiometry of the reaction:
1 mole of KOH produces 1 mole of potassium sulfate
So, 0.424 moles of KOH will produce = of potassium sulfate
Now, calculating the mass of potassium sulfate from equation 1, we get:
Molar mass of potassium sulfate = 174.26 g/mol
Moles of potassium sulfate = 0.424 moles
Putting values in equation 1, we get:
Hence, the mass of potassium sulfate that can be produced is 73.88 grams
