Ge and As
they are lined up between the non metals and metals so they are metalloids
Most nonmetallic solids have the property of brittleness.
Take the molar mass of U and add it to the molar mass of F(3).
Answer:
0.2042 M is the original concentration of (aq) in the titrating solution.
Explanation:
Mass of = 0.217 g
Moles of
1 mole of have 2 mole of As and 1 mole of have 1 mole of As.
So, from 1 mole of we will have 2 moles of
Then from 0.001096 mol of :
of
According to reaction, 1 mole of reacts with 2 mole of cerium (IV) ions,then 0.002192 mol of
of cerium (IV) ions.
Volume of the acidic cerium{IV) sulfate = 21.47 ml =0.02147 L
1 mL = 0.001 L
0.2042 M is the original concentration of (aq) in the titrating solution.
