Answer:
See explanation
Explanation:
CO2 reacts with water to form carbonic acid as follows;
CO2(g) + H2O(l) ---------> H2CO3(aq)
This makes the solution more acidic hence it will require more NaOH to reach end point due to the increase in acidity.
Hence, if CO2 is not removed by boiling the solution, a greater amount of NaOH is required to reach end point.
Answer:
ν = 1483.939 m/s
Explanation:
Wave propagation speed (ν):
∴ Wavelength ( λ ) = 4.25 m
∴ Period ( T ) = 1 / f
∴ frequency ( f ) = 349.2 Hz ( s-1 )
⇒ T = 1 / 349.2 s-1
⇒ T = 2.864 E-3 s
⇒ ν = (4.25 m) / (2.864 E-3 s)
⇒ ν = 1483.939 m/s

Hello!</h2>
The answer is:
There are 732.24 grams of Dinitrogen Pentoxide
in 6.78 moles of the same compound.
<h2>
Why?</h2>
The dinitrogen pentoxide, or nitrogen pentoxide, is a rare salt that consists of anion and cations, and it's an important compound when preparing some kinds of explosives.
So, to answer the question, first, need to look for the molecular formula of the dinitrogen pentoxide, then, use it to calculate the mass in gram of 6.78 moles of the same compound.
The dinitrogen pentoxide formula is:
![N_{2}O_{5}](https://tex.z-dn.net/?f=N_%7B2%7DO_%7B5%7D)
Where, the molar mass of each element are:
![N=\frac{14g}{mol}](https://tex.z-dn.net/?f=N%3D%5Cfrac%7B14g%7D%7Bmol%7D)
![O=\frac{16g}{mol}](https://tex.z-dn.net/?f=O%3D%5Cfrac%7B16g%7D%7Bmol%7D)
Calculating the molar mass of the compound, we have:
![N_{2}O_{5}=2*(\frac{14g}{mol})+5*(\frac{16g}{mol})](https://tex.z-dn.net/?f=N_%7B2%7DO_%7B5%7D%3D2%2A%28%5Cfrac%7B14g%7D%7Bmol%7D%29%2B5%2A%28%5Cfrac%7B16g%7D%7Bmol%7D%29)
![N_{2}O_{5}=(\frac{28g}{mol})+(\frac{80g}{mol})=(\frac{108g}{mol}](https://tex.z-dn.net/?f=N_%7B2%7DO_%7B5%7D%3D%28%5Cfrac%7B28g%7D%7Bmol%7D%29%2B%28%5Cfrac%7B80g%7D%7Bmol%7D%29%3D%28%5Cfrac%7B108g%7D%7Bmol%7D)
Now, calculating what is the mass of 6.78 of
, we have:
![mass=moles*MolarMass=6.78mol(N_{2}O_{5})*\frac{108g}{mol}=732.24g(N_{2}O_{5})](https://tex.z-dn.net/?f=mass%3Dmoles%2AMolarMass%3D6.78mol%28N_%7B2%7DO_%7B5%7D%29%2A%5Cfrac%7B108g%7D%7Bmol%7D%3D732.24g%28N_%7B2%7DO_%7B5%7D%29)
So, there are 732.24 grams of Dinitrogen Pentoxide
in 6.78 moles of the same compound.
Have a nice day!
Ba(NO₃)₂ + Na₂SO₄ → 2NaNO₃ + BaSO₄
The reaction goes to completion because it has the same amount of elements in the reactants and products.
