DiPhosphorus pentoxide or pentaoxide
Hello!
The balanced chemical equation for the rusting of iron is the following:
4 Fe + 3 O₂ → 2Fe₂O₃
The coefficients to balance the equation are 4,3,2. The fundament of this balance is the Law of Conservation of Mass. This Law states that matter is neither created nor destroyed in a chemical reaction, and in a chemical equation, the moles of each atom is conserved in both sides of the arrow. That means that if 4 Fe atoms are on the left side, 4 Fe atoms should be on the right side.
A suggestion for balancing equations is to start with metal atoms, continuing with non-metals, then hydrogen and lastly oxygen.
Have a nice day!
The distance from one point to another is the distance traveled by a light beam between them.
If you have the coordinates of the 2 points, then the distance between them is
√ of [ (the difference in their x-values)² + (the difference in their y-values)² ]
Answer : The amount of water lost was, 333.4 grams.
Explanation : Given,
Heat released = 753480 J
Formula used :

where,
Q = heat released = 753480 J
m = mass = ?
L = latent heat vaporization of water = 
Now put all the given values in the above formula, we get:


Thus, the amount of water lost was, 333.4 grams.

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:

Where, the molar mass of each element are:


Calculating the molar mass of the compound, we have:


Now, calculating what is the mass of 6.78 of
, we have:

So, there are 732.24 grams of Dinitrogen Pentoxide
in 6.78 moles of the same compound.
Have a nice day!
