Carbon has 6 protons and boron only has 5
the poly atomic molecule is H2
Recall the ideal gas law,
<em>P V</em> = <em>n R T</em>
Find the amount of CO₂ in the sample, <em>n</em> :
<em>P</em> = 686 mm Hg ≈ 91,459 Pa
<em>V</em> = 6.34 L
<em>R</em> = 8.3145 J/(mol•°K)
<em>T</em> = 73 °C = 346.2 °K
→ <em>n</em> = <em>P V</em> / (<em>R</em> <em>T</em> ) ≈ 0.20147 mol
Now find the volume <em>V</em> of the sample when the temperature <em>T</em> is 35 °C = 308.2 °K :
<em>V</em> = <em>n R T</em> / <em>P</em> ≈ 5.6349 L ≈ 5.63 L
The Brønsted-Lowry base in the given reaction is NH₂⁻. The correct option is the fourth option NH2−
To determine which is the Brønsted-Lowry base in the given reaction:
NH2−+CH3OH→NH3+CH3O−
First, we will write the equation for the reaction properly
The equation is:
NH₂⁻ + CH₃OH → NH₃ + CH₃O⁻
Now, to determine which among the species in the above reaction is the Brønsted-Lowry base, we will start by defining what a <em>Brønsted-Lowry base</em><em> </em>is.
A Brønsted-Lowry base is any species that is capable of accepting a proton, which requires a lone pair of electrons to bond to the H⁺.
In simple terms, a Brønsted-Lowry base is a proton acceptor.
In the above reaction, NH₂⁻ is the species that is capable of accepting a proton and it has a lone pair of electrons to bond to the H⁺.
∴ NH₂⁻ is the Brønsted-Lowry base in the reaction
Hence, the Brønsted-Lowry base in the given reaction is NH₂⁻. The correct option is the fourth option NH2−
