Answer:
t = 49.20 years
Explanation:
Half life expression for first order kinetic is:
Half life = 12.3 years
Where, k is rate constant
So,
The rate constant, k = 0.05635 years⁻¹
Using integrated rate law for first order kinetics as:
Where,
is the concentration at time t
is the initial concentration
Given:
is 6.25 % of . So,
= 0.0625
t = ?
<u>t = 49.20 years</u>
Three resonance structures can be drawn for the allyl cation while two resonance structures can be drawn for the amidate ion.
Sometimes, we cannot fully describe the bonding in a chemical specie using a single chemical structure. In such cases, we have to use a number of structures which cooperatively represent the actual bonding in the molecule. These structures are called resonance or canonical structures.
The resonance structures of the allyl cation and the amidate ion are shown in the images attached to this answer. These structures show the different bonding extremes in these organic ions.

<span>How many moles of acetic acid and of sodium acetate are present in 50.0 mL of solution?
We calculate it as follows:
moles of acetic acid = .120 mol/L (.050 L ) = 0.006 mol
moles of sodium acetate = 0.150 mol/L (0.050 L) = 0.008 mol
Hope this answers the question. Have a nice day.</span>

In a chemical formula, the elements in a compound are represented by their chemical symbols, and the ratio of different elements is represented by subscripts. Consider the compound water as an example. Each water molecule contains two hydrogen atoms and one oxygen atom
