Roman numerals are used in naming ionic compounds when the metal cation forms more than one ion. The metals that form more than one ion are the transition metals, although not all of them do this.
SnBr2 - Tin(II) Bromide
Answer:
0.07
Explanation:
to find mole you divide mass by the relative atomic mass
Now you find the relative atomic of of moles pf he number sodium sulfide
then you thequation for finding moles to find mole of sodium
Answer:
51.34 %
Explanation:
You first need to calculate the theoretical yield of Bromobutane taking into account the amount of initial Butanol doing some stoichiometric calculations:
Then you calculate the yield giving the real amount you produced:
<span>26.35 ml NaOH x (.1650 moles NaOH / 1000 ml ) x (1 mole H2SO4 / 2 moles NaOH) = moles H2SO4 = .002174 moles H2SO4
molarity of H2SO4 = .002174 / .035 L = .06211 M</span>
