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 :
The correct answer is Ag.
Ag is the element that is undergoing reduction in the given reaction. Reduction refers to a gain of electrons and a decrease in oxidation number. So based in all the given reaction, Ag is the element that is undergoing reduction. I hope this answer helped you.
Determine the mass of each of the following amounts. a. 1.366 mol of
NH3
, b. 0.120 mol of glucose,
C6H12O6
, c. 6.94 mol barium chloride,
BaCl2
, d. 0.005 mol of propane,
C3H8
<h3>Answer:</h3>
C. 9
<h3>Explanation:</h3>
There are 2 electrons in the first shell, and 7 in the second, for a total of 9.
A flouride ion, on other hand, would have 8, since it fills that second shell with an extra electron (that's why it has a charge of -1)
