What is the formal charge of nitrogen in no2cl

Chemistry
1 answer:
Gre4nikov [31]3 years ago
6 0

Answer:

The formal charge on nitrogen in NO_{2}Cl is +1.

Explanation:

The structure of NO_{2}Cl is as follows.

(In attachment)

Formal\, charge = Valence\, electron - (nonbonding\, electrons + \frac{Bonding\,electrons}{2})

From the structure, Nitrogen has no non bonding electrons. Nitrogen has four bonds and each bond corresponds to 2 electrons. Hence, nitrogen have eight bonding electrons and five valence electrons.

Formal\,charge\,on\,nitrogen = 5-[0+ \frac{8}{2}]= +1

Therefore, The formal charge on nitrogen in NO_{2}Cl is +1.

A reaction known to be first-order has a half-life of 23.6 min. If the initial concentration of the reactant is 2.50 M, what wil
Scrat [10]
First i wanted to say you look preety LOL

1) Determine the rate constant for the reaction: 

<span>k = (ln 2) / t_1/2 <--- I'll leave you to figure out how that came to be. Hint: use the integrate form of the first-order rate law </span>

<span>k = (ln 2) / 23.6 min </span>

<span>k = 0.02937 min^-1 <--- keep a few extra digits </span>

<span>1) use the integrated form of the first-order rate law: </span>

<span>ln A = -kt + ln A_o </span>

<span>ln A = - (0.02937 min^-1) (120 min) + ln 2.50 </span>

<span>ln A = -3.5244 + 0.91629 </span>

<span>ln A = -2.60811 </span>

<span>A = 0.07367 M <--- round off more as you see fit </span>

<span>Here's another way: </span>

<span>120 min / 23.6 min = 5.106383 half-lives </span>

<span>(0.5)^5.106383 = 0.02902856 <--- the decimal amount remaining after 5.106383 half-lives </span>

<span>0.02902856 x 2.50 M = the answer</span>
