Answer:
is the isotopic notation of the atom
Explanation:
The isotope notation is:
<em>Where a is the mass number = Number of protons + Number of neutrons</em>
<em>b is atomic number = Number of protons</em>
The atomic number define the nature of the atom, the element with atomic number = 15 is phosphorus, P:
a = 15 protons + 16 neutrons = 31
b = 15
is the isotopic notation of the atom.
<u>Answer:</u> The value of is
<u>Explanation:</u>
We are given:
Initial moles of ammonia = 0.0280 moles
Initial moles of oxygen gas = 0.0120 moles
Volume of the container = 1.00 L
Concentration of a substance is calculated by:
So, concentration of ammonia =
Concentration of oxygen gas =
The given chemical equation follows:
<u>Initial:</u> 0.0280 0.0120
<u>At eqllm:</u> 0.0280-4x 0.0120-3x 2x 6x
We are given:
Equilibrium concentration of nitrogen gas =
Evaluating the value of 'x', we get:
Now, equilibrium concentration of ammonia =
Equilibrium concentration of oxygen gas =
Equilibrium concentration of water =
The expression of for the above reaction follows:
Putting values in above expression, we get:
Hence, the value of is
