Santa Fe was occupied by the Pueblo Indians as early as 1050. Spanish presence begins with Francisco Coronado's expedition in 1515. Don Juan Onate established his Capital at t…he San Juan Pueblo North of Santa Fe and it did not become the Center of New Mexico until the third Governor Pedro de Perlata. As a town, most use Juan Martinez de Montoya and the date of 1607. (MORE)
Yes because "he" sucks!!.
and because Fe means Faith and yup Faith is a loser and chupar means sucks in Spanish.
Faith is actually a girl but everybody in "his" class hate…s "him" :).
def. of faith: a feminen name..
but in this case it's a masculine/feminen name. (MORE)
Fe 3+ is smaller. Its ionic radius is 63 pm, while Fe 2+ has an ionic radius of 77 pm. (For comparison, the Fe atom has a radius of 140 pm.) This is because the outermost …electron in the 2+ ion is pulled off to form the 3+ ion. This outermost electron was the most weakly held. The remaining electrons are closer to the nucleus. (MORE)
It's most likely 60 Fe, also written iron-60, which is an isotope of iron with 60 nucleons (protons and neutrons). It doesn't occur in nature to any significant degree. It's …radioactive with a half-life of about 2.5 million years and decays via beta emission to 60 Co. (MORE)
Fe has an oxidation number of .
+2 in ferrous salts .
+3 in ferric salts As Br has an oxidation number of -1 in bromide, only two salts of Fe with Br are possible: .
…FeBr 2 = ferrous bromide .
FeBr 3 = ferric bromide .
and FeBr DOES NOT EXIST (MORE)
In assigning formal oxidation states it is necessary to consider the bonding present amongst the species involved. FeS 2 was one of the earliest crystal structures solved b…y X-ray diffraction methods and the simple cubic crystals clearly show sulphur-sulphur bonding within [S-S] 2- units. These can be viewed as derived from hydrogen disulphide, H 2 S 2 ( cf. hydrogen peroxide, H 2 O 2 ). Thus FeS 2 would be better described as iron persulphide rather than disulphide. In considering the material as Fe 2+ S 2 2â it is clear that the oxidation state of Fe is +2 while that of each S moeity is -1. A similar problem can be posed via barium peroxide, BaO 2 , where the oxidation state of barium must be +2 (metal in Gp 2). What is the oxidation state of oxygen in Ba O 2 ? (MORE)
Yes, if the iron ion is iron(II), which means it has a charge of 2 + . FeS is called iron(II) sulfide. If the iron ion is iron(III), with a charge of 3 + , then the formula un…it would be Fe 2 S 3 , and would be called iron(III) sulfide. (MORE)
Fe(AlO 2 ) 2 iron(II) aluminate is better written as FeAl 2 O 4 , and is better described as a mixed oxide with close packed oxide ions and Fe 2+ and Al 3+ occupying tetrah…edral and octahedral sites, a spinel structure. (MORE)
A single gram atomic mass of iron is usually considered to be the functional equivalent of a mole of metallic iron, because iron atoms do not form well characterized polyatomi…c entities with themselves. Therefore, 0.26 "mole" of iron contains 0.26 X Avogadro's Number of atoms, or 1.6 X 10 23 atoms, to the justified number of significant digits. (MORE)
