b ) 19.78 grams N2
sorry..i only have time to do the first two :)
Explanation:
Answer:
3.0 L of NH₃
Solution:
The equation is as follow,
N₂ + 3 H₂ → 2 NH₃
According to equation,
67.2 L (3 mole) H₂ at STP produces = 44.8 L (3 mole) of NH₃
So,
4.50 L of H₂ will produce = X L of NH₃
Solving for X,
X = (4.50 L × 44.8 L) ÷ 67.2 L
X = 3.0 L of NH₃
According to Bronsted theory of acid and base, an acid in a proton donor while base is a proton acceptor. Acid donates the proton to form conjugate base, while base accepts proton to form corresponding conjugate acid.
For the reaction,
<span>hpo2− 4 (aq) + hno3(aq) </span>⇔<span> no− 3 (aq) + h2po− 4 (aq)
In above forward reaction, hno3 donotes proton to form no-3, hence no-3 is a conjugate base. </span>
