d)Ka for amilimium ion, (C6H5NH3)^+
C6H5NH3^+ + H2O ⇋
C6H5NH2 + H3O^+ </span><span>
<span>Ka = [C6H5NH2][H3O^+] / [C6H5NH3^+]</span></span>
<span>B. The ignition point for a given fuel is met.</span>
Answer:
<h2>367.5 J</h2>
Explanation:
The potential energy of a body can be found by using the formula
PE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 9.8 m/s²
From the question we have
PE = 3 × 9.8 × 12.5 = 367.5
We have the final answer as
<h3>367.5 J</h3>
