2 C3H6 + 2 NH3 + 3 O2 -> 2 C3H3N + 6 H2O
Molar masses
C3H6: 42.08 g/mol
NH3: 17.03 g/mol
O2: 32 g/mol
CH3H3N: 53.06 g/mol
H2O: 18 g/mol
# of moles
C3H6: 15.0 g / [42.08 g/mol] = 0.356 mol
NH3: 5.00 g / [17.03 g/mol] = 0.294 mol
O2: 10.0 g / [32 g/mol] = 0.313 mol
Now wee need to find the limitant reactant
The theoretical proportion is 2:2:3, equivalent to 1:1:1.5
The proportion ot the given gases is 0.356 : 0.294 : 0.313, dividing by 0.294 that is equivalent to: 1.2 : 1 : 1.06, where you see that O2 is below the theoretical proportion and it is the limitant reactant.
Now, from the equation you have 3 mol of O2 produces 2 mol of acrylonitrile (C3H3N)
Then you will obtain 0.313 * 2/3 = 0.209 mol acrylonitrile
The mass is 0.209mol * 53.06 g/mol = 11.07 g acrylonitrile
Answer: 11.07 g
<u>Answer;</u>
-energy
According to the Kinetic Molecular Theory, the absolute temperature of a gas is directly related to average molecular kinetic<u> energy</u>.
<u>Explanation;</u>
- Kinetic molecular theory is a theory that explains that the particles of a gas are in constant random motion, exhibiting perfectly elastic collisions.
- This theory may be explained using Boyle's and Charles's law. Such that the average kinetic energy of a given particles of a gas is directly proportion to the absolute temperature.
Answer:
[H+] =3.1 x 10-4 M more acidic
Explanation:
3.1 x 10-4 M >> 2.5 x 10-10 M,
so solution with [H+] =3.1 x 10-4 M has more H+ ions, and because of it, this solution is more acidic.
The correct answer is the octet rule.
Octet rule states that atoms tend to bond in order to have 8 electrons in their outer most electron orbit achieve stable configurations of noble gases.
When atoms form covalent bonds, they achieve the goal of having 8 electrons by sharing the electrons.
In ionic bond, atom either gain or lose an electron and form ions that have the stable configuration of 8 valence electrons.
Not all atoms follow the octet rule and there are many exceptions and variations.
