Update:

Oops, [Mn(Cl)6]4-

    Hi Nicole: Your other helper appears to have gone AWOHL so let me give you some pointers. Oxidation state (x) of Mn is x - 6(6Cl-) = 4- so this is Mn(II); work out how many d electrons Mn(II) has knowing that the 4s2 electrons are lost first. High spin means max number of unpaired electrons. I always found it surprising that some TM cmplxs had this number of u p e, but Mn(II) cmplxs are quite stable. cheers, drp

    possibly much greater importantly, a theory is an evidence of information that are already prevalent to exist. meaning that Darwin (as an occasion) did not invent the information, he in basic terms defined them. No rational observer puzzled the information on the time. they might have argued together with his clarification of them, yet not with the information. or perhaps 150 years in the past, it replaced into prevalent to be a fact that species developed over geologic time. The creationists that attempt to disclaim this are even added at the back of than non secular believers have been interior the mid-nineteenth century. ---------- @ Dennis - re: "implying that scientists are ideal." possibly you're able to re-study the question. relatively this section: >> human beings look to think of that this may be a wager. it relatively is not, neither is it absolute. A theory and a regulation may be changed as greater suggestion is accrued. and attempt to tell a choose that the call he in basic terms rendered replaced into "in basic terms a wager." enable's see how a methods you get with that. it relatively is real that ninety 9% isn't one hundred.00% even with the undeniable fact that it is not a wager.

    you need to clarify the formula of the compound. Something is missing ... there is an unmatched parenthesis.
