Cadmium chloride is a highly soluble compound. The equation for its dissolution is:

CdCl₂(s) → Cd⁺²(aq) + 2Cl⁻(aq)

This dissociation in water allows for the cadmium and chlorine ions to take part in reactions. This is the reason that solutions of chemicals are prepared when a reaction needs to take place.

<h3><u>Answer;</u></h3>

CO3^2- and O3

<h3><u>Explanation;</u></h3>

Ozone, O3 is a molecule composed of three oxygen atoms joined together. Two oxygen atoms joined together form the basic oxygen molecule O2.
A polyatomic ion is a charged particle which has two or more atoms held together by covalent (sharing of pairs of electrons) bonds.
Carbonate (CO3^2-) is an example of polyatomic ion. It can not be adequately described using Lewis structure.

If you want to determine the actual salicylate concentration for a sample that gives a greater absorption than the highest conce

Anarel [89]

Answer: The concentration of unknown sample is 1.8 mg/ml

Explanation:

According to the dilution law,

$M_1V_1=M_2V_2$

where,

$M_1$ = concentration of stock solution = ?

$V_1$ = volume of stock solution = 0.25 ml

$M_1$ = concentration of diluted solution = 0.45 mg/ml

$V_1$ = volume of diluted solution = (0.25+0.75) ml = 1.00 ml

Putting in the values we get:

$M_1\times 0.25=0.45\times 1.00$

$M_1=1.8mg/ml$

Therefore, concentration of unknown sample is 1.8 mg/ml

Complete Question

The complete question is shown on the first uploaded image

Answer:

a

$2NO_2 _{(g)} + F_2_{(g)} ----> 2NO_2 F_{(g)}$

b

$r = \frac{ k [NO_2]^2 [F_2]}{[NO_2F]}$

Explanation:

From the question we are told that

The formation mechanism is

$NO_2_{(g)} + F_2 _{(g)} ----> NO_2 F_{(g)} + F_{(g)}$

$F_{(g)} + NO_2 _{(g)} ---> NO_2 F_{(g)}$

The overall balanced equation is

$2NO_2 _{(g)} + F_2_{(g)} ----> 2NO_2 F_{(g)}$

We combined the first reactant and the last product and the balanced the number of mole

The observable rate law is

$r = \frac{ k [NO_2]^2 [F_2]}{[NO_2F]}$

This rate law is derived from the balanced chemical equation
