Carbon disulfide (cs2) undergoes a single displacement reaction with o2 to form co2. if 100 grams of cs2 reacts with 38 grams of o2, what will the limiting reagent be?
cs2 + o2 co2 + 2s

Explanation:

Moles of

Moles of

For the given chemical reaction, the equation follows:

By Stoichiometry:

1 mole of  oxygen reacts with 1 mole of carbon disulphide

So, 1.2 moles of oxygen reacts with = of carbon disulphide

As, the required amount of carbon disulphide is more than the required amount. Hence, it is considered as the excess reagent.  (1.3-1.2)= 0.1 mole will be left unused.

Oxygen is considered as a limiting reagent because it limits the formation of product.

false

because it does not have the potential to be entirely used up

thats how its supposed to be
