The concentration of AB, in mol/dm³, after 6 minutes : 0.125
<h3>
Further explanation</h3>
For first-order reaction :
The half-life of the reaction is 2 minutes⇒t1/2=2 minutes
The concentration of AB, in mol dm, after 6 minutes ⇒ t=6 minutes
The rate constant (k) :
The concentration after 6 minutes :
Hydrogen in heavy water is an isotope of Hydrogen (Deuterium)
so, it's different
Answer:
D) energy required to remove a valence electron
Explanation:
Ionization energy can be defined as the atom's ability to and the energy required to remove a valence electron. Ionization energy increases up a group and to the right along a period. So helium has the highest first Ionization energy meaning that it is very hard to remove an electron from helium because octet is already complete.
Answer:
B-It provides an explanation for many observations and accepted hypotheses.
