Answer:
- <u>two molecules of ammonia are formed by the reaction of one nitrogen and three hydrogen molecules.</u>
Explanation:
The balanced chemical equation provides information on:
- <u>Reactants</u>: those are the compounds that appear of the left side of the equation, each with its chemical formula.
- <u>Products</u>: those are the compounds that appear on the right side of the equation, again, each with its chemical formula.
- <u>Ratio</u>: the coefficients of each compound (the number to the left of the chemical formula) represent the ratio of the number of molecules that react and are formed.
In the given equation you have:
- Equation: N₂ + 3H₂ → 2NH₃
- The coefficients are 1 for nitrogen, 3 for hydrogen, and 2 for ammonia. Hence, 2 molecules of ammonia are formed by the reaction of 1 molecule of nitrogen and 3 molecules of hydrogen.
Answer:
17.27 atm
Explanation:
Use the ideal gas law or PV = nRT
We are solving for pressure here so lets isolate for P before we plug in values:
![P = \frac{nRT}{V}](https://tex.z-dn.net/?f=P%20%3D%20%5Cfrac%7BnRT%7D%7BV%7D)
So first to get n or the number of moles we need to convert the grams of N2O to moles of N2O. We can do this by multiplying by the inverse of the molar mass like so:
![\frac{519.93g(N2O)}{1} \frac{mol}{44.013g(N2O)}](https://tex.z-dn.net/?f=%5Cfrac%7B519.93g%28N2O%29%7D%7B1%7D%20%5Cfrac%7Bmol%7D%7B44.013g%28N2O%29%7D)
Our grams of N2O would cancel and give us 11.813 mol of N2O
Now all thats left is to plug in and solve with the correct value for R which in this case for all of our units to cancel is 0.08206
![P = \frac{(11.813)(0.08206)(125.63)}{7.05}](https://tex.z-dn.net/?f=P%20%3D%20%5Cfrac%7B%2811.813%29%280.08206%29%28125.63%29%7D%7B7.05%7D)
P = 17.27 atm
(I would double check the calculator work if it is for correctness just be sure)
Is it because the bonds between hydrogen molecules for easier than bonds between chlorine molecules?
Answer:
Explanation:
Heat of vaporization is the amount of energy (enthalpy) that must be added to a liquid substance, to transform a quantity of that substance into a gas. Heat of Vaporization is also known as heat of evaporation
