For the reaction: N2O5(g) \longrightarrow⟶ 2NO2(g) + 1/2O2(g)
ivanzaharov [21]
The given equation from the problem above is already balance,
                                 N2O5 ---> 2NO2 + 0.5O2
Since, in every mole of N2O5 consumed, 2 moles of NO2 are formed, we can answer the problem by multiplying the given rate, 7.81 mol/L.s with the ratio.
                    (7.81 mol/L.s) x (2 moles NO2 formed/ 1 mole of N2O5 consumed)
                       = 15.62 mol/L.s
The answer is the rate of formation of NO2 is approximately 15.62 mol/L.s.

Which is an example of a building block that helps form DNA? cytosine polypeptide ribose uracil
AnnyKZ [126]
<span>Cytosine is a building block of DNA,
 it is a component to DNAs base pairs and pairs with guanine (these pairs make up the rungs of its double helix)... it is not Ribose as plain Ribose has a hydroxyl group where a hydrogen atom should be if it were to be found in DNA and be deoxyribose (hence deoxyribonucleic acid and not ribonucleic acid since ribonucleic acid is RNA). Uracil is only found in RNA and actually takes Cytosine's place in the rungs of RNA and binds with guanine (although RNA is not in the conventional double helix shape and more resembles a protein in shape). Polypeptide is a long peptide chain and usually associated with proteins and not DNA....</span>

qwelly [4]
It’s a chemical reaction I guess? Or maybe it hits the water and unlike a solid and it being a liquid it goes into the water causing it to spread or something like that.
