If 4.00 g of nacl react with 10.00 g of agno3, what is the excess reactant?
agcl

Answer : The excess reagent is,

Explanation : Given,

Mass of NaCl = 4 g

Mass of = 10 g

Molar mass of NaCl = 58.44 g/mole

Molar mass of = 169.87 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 moles of react with 1 mole of

So, 0.059 moles of react with 0.059 mole of

From this we conclude that, is an excess reagent because the given moles are greater than the required moles and is a limiting reagent and it limits the formation of product.

Hence the excess reagent is,

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
