Analyze the Name of complex Compound.
T<span>etracarbonylplatinum(iv) chloride
So, there are,
4 Carbonyl groups = 4 CO = (CO)</span>₄
1 Platinum Metal = 1 Pt = Pt
Unknown Chloride atoms = ?
In complexes positive part is always named first, so the sphere containing Pt and carbonyl ligands is written first,
[Pt (CO)₄]
The charge on sphere is +4 because CO ligand is neutral, and Pt has a Oxidation state of four as written in name (IV),
So,
[Pt (CO)₄]⁴⁺
Now, in order to neutralize +4 charge we should add 4 Chloride ions, So,
[Pt (CO)₄] Cl₄
Answer:
Activation energy, Ea, for the reaction 261.7 kj/mole
Explanation:
Given
Rate constant at 470 ⁰C (K₁) = 1.10 x 10⁻⁴ s⁻¹ and rate constant at 500⁰C (K₂) = 5.7 x 10⁻⁴ s⁻¹
Temperature (T₁) = 470 + 273 = 743 K and
temperature (T₂) = 500 + 273 = 773 K
Activation energy (Eₐ) = ?
Universal gas constant (R) = 8.314 J. K⁻¹. mole⁻¹
We know log
= 
⇒ log 
= 
⇒ 0.714 = 
⇒ Eₐ = 
j/mole = 261.7 Kj/mole
Answer:
You need 4 moles of HCl to produce two moles of H2
Explanation:
You can simplify mole and 2 mole into 1 and 2
So how many HCl do you need to make H2?
There are one Hydrogen molecule in Hcl And you need 2 to make a H2
And to make two of each you need to multiply 2 by 2 which is 4
So you need 4 moles of HCl to produce two moles of H2
Hope this helps!
Answer:
The effective nuclear charge for a 2nd row electron in Sulfur is +8
Explanation:
Zeff = Z (# of protons) - S (# of shielded electrons)
Since there are 8 electrons in the first and second rows combined, there are 8 shielding electrons.
The number of protons in Sulfur is 16.
Therefore,
Zeff = 16 - 8
Zeff = 8
(It's been awhile, so I am not 100% sure)
