In coordination compounds , first of all look at the hybridisation of the central metal atom and also the lone pairs present. That will help you out to tell the shape and geometry.
advance happy birthday sahil annaya and answer my question i cannot understand organic chemistry?? plz suggest me
As the nuclear charge will increase the size of atom should decrease as the force of attraction batween the electrons and nucleous increases …...........but this doesn’t happen in every case...
H, friend.You cannot find molecular formula if only vapour density is given to you.You can just find the molecular weight by multiplying vapour density with 2.Could you please approve my answer...
Since iron is found 0.33% by weight it means in 100 g of Hb. iron present = 0.33 in 67200 g of Hb, iron present = (0.33/100)*67200 Now atleast 1 atom should be present in its 1 molecule = 56g 56 g = 1...
n factor is atomic weight or molecular weight by equivalent weight. n factor for acids is itsbasicity,ie, no of replaceablehydrogen ionper molecule. for eg HCl has n factor=1 n factor of H2SO4 =2...
Its from the salt analysis that you do in your laboratory
(chcooh) okkkk byeeeeeeeee all the best for your bright future
Ni is in the +2 oxidation state i.e., in d8 configuration.In case of [NiCl4] 2−, Cl− ion is a weak field ligand. Therefore, it does not lead to the pairing of unpaired 3d electrons....
Theinert pair effectis the tendency of the electrons in the outermost atomic s orbital to remain unionized or unshared in compounds of post-transition metals.In other words we can say that down the...

IN CASE OF OXALIC ACID TO BREAK THEIR BONDS HEAT IS REQUIRED THEN ONLY IT FORMS NEW BONDS WITH OTHER SUBSTANCE IT NEARLY 60 DEGREES
#Method 1 n*s n-4*h n-3*g n-2*f n-1*d n*p Put value of n. If orbital exists then count 2e- per orbital (2h or 3g do not exist). Sum up the electrons. Gives the no. of elements in a period. #Method 2...
