That's what I know so far and took notes on hope it helped:)
The coordination compounds' names or formulas, the oxidation state of each metal ion, and the electronic configuration of the each metal ion.
1. [V(OH2)6](NO3)3 - Vanadium(V) Oxidation State: +5 Electronic Configuration: [Ar] 3d3 4s2

What is Electronic Configuration?
The arrangement of an atom's or molecule's (or other physical structure's) electrons in their atomic or molecular orbitals is known as the electron configuration in atomic physics as well as quantum chemistry. For instance, the neon atom's electron configuration is 1s2 2s2 2p6, which means that 1, 2 and 6 electrons, respectively, are present in each of the 1s, 2s, and 2p subshells. According to electronic configurations, each electron moves independently within an orbital while being surrounded by an average field produced by all other orbitals. Slater determinants as well as configuration state functions are used to mathematically describe configurations.

The solution would be like
this for this specific problem:
Molecular formula of the
two substances: Na2(CO3) and Na(HCO3)
<span>3M * .07L = .21mol </span><span>
<span>1M * .03L
= .03mol </span></span>
<span>.42mol+.03mol = .45mol
Na </span>
30mL + 70mL=100mL or .1L
.45mol/.1L is 4.5M
So the sodium ion concentration is 4.5M. I am hoping that this
answer has satisfied your query and it will be able to help you in your
endeavor, and if you would like, feel free to ask another question.
Explanation:
Experiment Initial [CS2] (mol/L) Initial Rate (mol/L·s)
1 0.100 2.7 × 10−7
2 0.080 2.2 × 10−7
3 0.055 1.5 × 10−7
4 0.044 1.2 × 10−7
a) Choose the rate law for the decomposition of CS2.
Comparing equations 1 and 3, reducing the initial concentration by almost half (from 0.100 to 0.055) leads too the rate of reaction to be reduced by almost half (from 2.7 × 10−7 to 1.5 × 10−7).
This signifies that the reaction is a first order reaction.
Rate = k [CS2]
(b) Calculate the average value of the rate constant.
Taking equation 1.
Rate = k [CS2]
k = Rate / [CS2]
k = 0.100 / (2.7 × 10−7) = 0.037 x 10^8 = 3.7 x 10^6s-1
