Answer:
4 moles of NH3 will be produced
Explanation:
The reaction expression is given as:
N₂ + 3H₂ → 2NH₃
We have to check that the equation of the reaction is balanced.
Then;
if 2 mole of N₂ reacts;
1 mole of N₂ will react with 3 mole of H₂ to produce 2 mole of NH₃
2 mole of N₂ will react with (2x3)mole of H₂ to produce (2x2)mole of NH₃
6mole of H₂ to produce 4 mole of NH₃
When a neutrally charged atom loses an electron to another atom, the result is the creation of two ions (cation and anion).
The answer is: b)16,200 seconds :)
Answer:
0.93 grams per milliliter
Explanation:
Density is the division of mass by volume. It is how "hefty" an object is; for example, wood isn't very "hefty" but metal is. The density is measured in mass over volume, so it is 9.3/10. After applying units, it is 0.93 grams per milliliter.
Explanation:
The given data is as follows.
Weight of solute = 75.8 g, Molecular weight of solute (toulene) = 92.13 g/mol, volume = 200 ml
- Therefore, molarity of toulene is calculated as follows.
Molarity = 
= 
= 4.11 M
Hence, molarity of toulene is 4.11 M.
- As molality is the number of moles of solute present in kg of solvent.
So, we will calculate the molality of toulene as follows.
Molality = 
= 
= 8.6 m
Hence, molality of given toulene solution is 8.6 m.
- Now, calculate the number of moles of toulene as follows.
No. of moles = 
= 
= 0.8227 mol
Now, no. of moles of benzene will be as follows.
No. of moles = 
= 
= 1.2239 mol
Hence, the mole fraction of toulene is as follows.
Mole fraction = 
= 
= 0.402
Hence, mole fraction of toulene is 0.402.
- As density of given solution is 0.857
so, we will calculate the mass of solution as follows.
Density = 
0.857
=
(As 1
= 1 g)
mass = 171.4 g
Therefore, calculate the mass percent of toulene as follows.
Mass % = 
= 
= 44.22%
Therefore, mass percent of toulene is 44.22%.
