HCI is the limiting reactant.
After converting grams to moles: there is one mole of HCI and 1.5 moles of NaOH. Since these combine in the ratio 1:1, when all the HCI has been consumed, there will be 0.5 moles of excess NaOH remaining.
Answer : The limiting reagent is, NaOH
Explanation : Given,
Mass of HCl = 30 g
Mass of NaOH = 20 g
Molar mass of HCl = 36.5 g/mole
Molar mass of NaOH = 40 g/mole
First we have to calculate the moles of and .
Now we have to calculate the limiting and excess reagent.
The balanced chemical reaction is,
From the balanced reaction we conclude that
As, 1 mole of react with 1 mole of
So, 0.82 moles of react with 0.82 moles of
That means, in the given balanced reaction, is a limiting reagent because it limits the formation of products and is an excess reagent.
Hence, the limiting reagent is NaOH
every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
