Probably CH(subscript)4... :) It's Methane
It is improbable that any specie with d0 or d10 will exhibit color in coordination compounds.
- If the central metal atom or ion in a coordination complex contains unfilled d orbitals, the compound exhibits color.
- Weak d–d transitions that produce spectral bands in the visible spectrum are thought to be the source of the colors.
- Hence, It is improbable that any specie with d0 or d10 will exhibit color in coordination compounds.
<h3>What are coordination compounds?</h3>
- Molecules that have one or more metal centers bonded to ligands are known as coordination compounds (atoms, ions, or molecules that donate electrons to the metal).
- These complexes may have a charge or be neutral.
- The complex is stabilized by nearby counter-ions when it is charged.

Answer:The acid is strong because it has a calculated K of 7.76x10*
The mass of this much chain is 0.22 grams for 7.5m of Grade 70 tow chain, which has a diameter of /38" and weighs 2.16/kgm, to tow a car.
<h3>What are weight and mass?</h3>
Mass is the amount of the substance and object and the weight is the gravitational force required to act upon the particular mass of the substance.
To calculate the mass of car divide the wight to the gravity value 9.8 meter per second.
mass = weight / gravity
substituting the value,
mass = 2.16 / 9.8
mass = 0.22 grams
Therefore,7.5m of Grade 70 tow chain, which has a diameter of /38" and weighs 2.16/kgm, to tow a car the mass will be 0.22 grams.

Answer:
[H⁺] = 3.02 x 10⁻¹⁰M
Explanation:
Given parameters:
pH of the solution = 9.52
Unknown:
Concentration of the solution
Solution
There is a relationship between the pH and concentration of a solution.
pH = -log₁₀[H⁺]
The unknown here is [H⁺],
Now making it the subject of the formula
[H⁺] = Inverse log₁₀(-pH)
[H⁺] = Inverse log₁₀(-9.52)
[H⁺] = 3.02 x 10⁻¹⁰M
