What is the volume (in liters) of a 5.98 gram sample of O2 at STP?

Chemistry
1 answer:
borishaifa [10]3 years ago

Answer:

4.186 L

Explanation:

Using the pv=nrt equation and converting the grams of O2 into mols. After finding the number of mols by dividing 5.98 by 32 (2*the atomic weight of O) you plug that into the equation. So then you have 1*V=.186875*.08206*273 then you rearrange the equation to solve for v and get 4.186 L

Stoichiometry: mole/ mole help
adell [148]

Answer:

<em>0.531 moles</em> of CO₂ are formed.

Explanation:

Given data:

Number of moles of CO = 0.531 mol

Number of moles of CO₂ formed = ?

Amount of oxygen = excess

Solution:

Chemical equation:

2CO + O₂    →    2CO₂

Now we will compare the moles of CO with CO₂.

              CO            :            CO₂

                2             :              2

              0.531        :          0.531

Thus, 0.531 moles of CO₂ are formed.

Resonance structures are not real. An individual resonance structure does not accurately represent the structure of a molecule o
tatiyna

Answer:

True

Explanation:

Resonance is a concept in chemistry that describes bonding in polyatomic molecules or ions whose structure cannot be efficiently described by a single Lewis structure. Individual resonance structures do not actually exist, that is, they are not real. None of the contributing resonance structures can be said to adequately represent the molecule or ion. However, the hybrid of all the possible resonance structures of the molecule or ion gives a holistic representation of the exact structure of the molecule or ion.
