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.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
