Give the formula of each coordination compound.?
Na2[PtCl4] [Fe(NH3)4(H2O)2]Cl3
Why is this formula useful?
That almost looks like the formula for variance, which is: variance = sum (a_i - mean)² That is, you the difference of each term a_i minus the mean (average) value, square that difference and add it to the sum. In your sequence, the average is 2.5 and the variance is: (1 - 2.5)² + (2 - 2.5)² + (3 - 2.5)² + (4 - 2.5)² = 2.25 + 0.25 + 0.25 + 2.25 = 5.0 Your formula takes the sum of the sequence first, subtracts the mean just once, and the squares that difference. Since the average is just the sum of the values divided by 4, then (sum of a - average of a) = (sum of a) - (sum of a)4 = (3/4)(sum of a) = (3/4)*10 = 7.5 Squaring that gives you 9/16 times the square of the sum. Not a particularly useful value by itself, but it is part of another formula to compute the variance. variance = [average value of a_i²] - [average value of a_i]² That's the average of the squares of the numbers, minus the square of the average of the numbers. Your expression is simply 9/16 times the second term in that formula.
What is the formula of each coordination compound?
a) Na[Ru(NH3)2(CO3)2] the carbonate CO^2- is a bidentate ligand to give Ru the normal octahedral coordination; it is a Ru(III) cmplx a common oxidation for Ru. b) Pt(NH3)2Cl2 a neutral Pt(II) square planar cmplx; it has cis and trans forms. The cis isomer is the famous anticancer drug cisplatin (Wikipedia)
What are the rules for writing formula of coordination compounds?
This is very simple way or rules to name or nomenclature the coordination compounds.I hope you understood.
What is a coordination compound?
If you know about covalent and ionic compounds, then coordination compounds are just basically a combination of the two.In covalent it is - “Here is my electron, you have one too. Let’s share them and be happy together!”In ionic it is - “I have an extra electron with me. I see that you require one electron more. Here, take it.”In coordination, it’s like - “I have some electrons with me. I see that you need some electrons. I can give them you (like ionic) but I will use them too (like covalent).”
What is a quadratic formula used for?
The quadratic formula is used to solve quadratic equations. A quadratic equation can be written in the form[math]a x^2+b x+c=0,[/math]where [math]a[/math], [math]b[/math] and [math]c[/math] are known and [math]x[/math] is unknown. The solutions are given by the quadratic formula, which is[math]x=\frac{-b\pm\sqrt{b^2-4a c}}{2 a}[/math].It only works if [math]a\neq 0[/math].
Is coordination in dance very important?
yesss…..exactly coordination is very important in any type of dance.“coordination “ basically means organizing people or groups so that they work together properly and well..Even simple steps with 100% coordination looks tremendous.If the whole team dance with a sync the energy as well as the confidence of the team eventually increases.Coordination with music beats can also not be ignored even when you are performing solo. But who says that a naagin-dance cannot be enjoyed on a punjabi dhol at a wedding. It can’t stop a person to climb a table and dance freely at his/her best friend’s bachelor/bachelorette party.
How to determine the coordination number?
because its a bidentate lignad... see these links-- http://en.wikipedia.org/wiki/Tris(ethyle... http://en.wikipedia.org/wiki/Ligand#Dent...
How do I calculate the coordination number of a compound?
Coordination Number refers to the number of atoms(or molecules or ions) attached to the central metal atom.To calculate the coordination no. of a compound , we see the constituents in the coordination sphere ( or the square bracket , emitting the outer atom/s ).For example:[Pt(en)2]CO3(bis(ethylenediamine)platinum(II) carbonate)The coordination sphere is [Pt(en)2]2+, since (CO3)2- exists as an anion.So here Pt is the central metal ion or the coordination center( which is generally a metal) is attached to 2 ions i.e (en) I.e ethylenediamine.So, since Pt is surrounded by 2 (en) in the coordination sphere ,And since en is a bi-dentate i.e attaches itself from two sides due to presence of lone pairs.we can say coordination no.
