how many boron atoms are in a molecule of borax (na2b4o7·10h2o)
Borax Borax is generally described as Na2B4O7·10H2O. However, it is better formulated as Na2[B4O5(OH)4]·8H2O, since borax contains the [B4O5(OH)4]2− ion. In this structure, there are two four-coordinate boron atoms (two BO4 tetrahedra) and two three-coordinate boron atoms (two BO3 triangles).
Barium acetate Barium acetate (Ba(C2H3O2)2) is the salt of barium(II) and acetic acid.
Period 3 element As the atomic number of elements in Period 3 increases, the atomic radius decreases.
Coulomb It is equivalent to the charge of approximately 7018624200000000000♠6.242×1018 (6995103600000000000♠1.036×10−5 mol) protons, and −1 C is equivalent to the charge of approximately 7018624200000000000♠6.242×1018 electrons.
Rubidium oxide The final product of oxygenation of Rb is principally RbO2, rubidium superoxide:
Rate equation k is the first order rate constant, which has units of 1/s or sâˆ’1.
