The color of the system will change between pink and blue depending on the concentration of species.

<h3>What is equilibrium?</h3>

Equilibrium is attained in a reaction when the rate of forward reaction is equal to the rate of reverse reaction. Now consider the equilibrium;

Co(H2O)6^2+(aq) + 4Cl^-(aq) ⇄ CoCl4^2-(aq) + 6H2O(l)

We know that Co(H2O)6^2+(aq) is pink while  CoCl4^2-(aq)  is blue hence, if the concentration of the species are changed, the color of the system will change accordingly.

What is the ph of a buffer prepared by adding 0.607 mol of the weak acid ha to 0.609 mol of naa in 2.00 l of solution? the disso
Paraphin [41]

Given:

0.607 mol of the weak acid

0.609 naa

2.00 liters of solution

 

The solution for finding the ph of a buffer:

[HA] = 0.607 / 2.00 = 0.3035 M 
[A-]= 0.609/ 2.00 = 0.3045 M 
pKa = 6.25 

pH = 6.25 + log 0.3045/ 0.3035 = 6.25 is the ph buffer prepared.

At a given temperature, the equilibrium constant for the formation of HI from H2 and I2 was found to be 29.9. Calculate the equi
evablogger [386]

Answer:

The correct answer is: K'= 0.033.

Explanation:

The formation of HI from H₂ and I₂ is given by:

H₂ + I₂ → 2 HI      K= 29.9

The decomposition of HI is the reverse reaction of the formation of HI:

2 HI → H₂ + I₂     K'

Thus, K' is the equilibrium constant for the reverse reaction of formation of HI. It is calculated as the reciprocal of the equilibrium constant of the forward reaction (K):

K' = 1/K = 1/(29.9)= 0.033

Therefore, the equilibrium constant for the decomposition of HI is K'= 0.033

1.02 mg of a compound that is known to absorb at 340 nm is dissolved and diluted to 5.00 mL in a volumetric flask. A 1.00 mL ali
Vinvika [58]

Answer:

6.97 X 10^{-4} M

Explanation:

The concentration of the analyte in the 5-mL flask would be 6.97 X 10^{-4} M

This is a problem of simple dilution that can be solved using the dilution equation;

C1V1 = C2V2,

where C1 = initial concentration, V1 = initial volume, C2 = final concentration, and V2 = final volume.

<em>In this case, the initial concentration (C1) is not known, the initial volume (V1) is 1.00 mL, the final concentration is 6.97 x 10-5 M, and the final volume is 10.00 mL.</em>

Now, let us make the initial concentration the subject of the formula from the equation above;

C1 = C2V2/V1. Solve for C1 by substituting the other parameters.

C1 = 6.97 x 10-5 x 10/1 = 6.97 X 10^{-4} M

A meterorite has velocity of 1544 m/s and a mass of 45 kg. Find its momentum
vichka [17]

Answer:

<h2>69,480 kg.m/s</h2>

Explanation:

The momentum of an object can be found by using the formula

momentum = mass × velocity

From the question we have

momentum = 45 × 1544

We have the final answer as

<h3>69,480 kg.m/s</h3>

Hope this helps you
