Lewis structure for nitrogen triiodide, NI(3)
Rasek [7]

Answer:

Lewis structure for nitrogen triiodide,NI_3 is given in the attachment.

Explanation:

Given:

The given compound is Nitrogen triiodide. In which 1 atom of Nitrogen combines with 3 atoms of Iodine. Both Nitrogen and Iodine are non-metals,So they form covalent bond by sharing of electrons.

The electron configuration of Nitrogen and Iodine is given below;

N(7) = 1s^2,2s^22p^3\\I(53) = 1s^2,2s^22p^6,3s^23p^63d^{10},4s^24p^64d^{10},5s^25p^5

There are 5 electrons in valance shell of Nitrogen atom and 7 electrons in valance shell of Iodine atom.

So, 3 atom of Iodine shares 1 electron with 1 electrons of Nitrogen.

The Lewis dot Structure is in the attachment.

Ok! Water is added to 200. ml of a 2.0 M solution of CaCI2 to increase the volume of the solution to 450. ml. So what is the new
dexar [7]

Answer:

0.89M

Explanation:

Because moles of solute do not change, we can write

M1V1 = M2V2

M - molarity, V - volume of solution

2.0M*200mL = M2*450mL

M2 = 0.89 M

Calculate the ph of a 0.25M solution of monochloroacetic acid at 25 c
Phoenix [80]
<h3>Answer: <em>pH=2.25 </em></h3>

Explanation:

monochloroacetic acid  also means: chloroacetic acid

pKa of monochloroacetic acid= 1.4 x 10^-3  (I believe this should have been given in the problem or perhaps in the textbook)

Formula: pH= pKa + log ( some number in M)

pH= -log (1.4 x 10^-3) + log (0.25M)= 2.85 + -0.602= 2.25

pH= 2.25
