Balance the reaction below and determine how many grams of nickel(II) phosphate will be formed when sodium phosphate (12.05g) is mixed with nickel(II) nitrate (175 mL, 0.500 M). After the reaction is complete, what is the concentration of the unprecipitated ion (either POX or Ni2+). Na3PO4 + Ni(NO3)2 — Ni3(PO4)2+ + NaNO3
Write the net ionic equation for the following molecular equation. 3CoCl2 (aq) + 2(NH4),PO(aq) Cos(PO4)2(s) + 6HCl(aq) (Use the lowest possible coefficients. Use the pull-down boxes to specify states such as (aq) or (s). If a box is not needed, leave it blank.)

Question 1 Give the expected charge of lithium (Li) when present in an ionic salt. If the charge cannot be determined using the periodic table, write 0 (zero). Answer Enter your answer here
1. A 5.000 gram sample of hydrated nickel (II) cyanide, Ni(CN)2·xH2O is heated according to the procedure described in this laboratory. After heating, the sample is found to weigh 3.029 grams. How many moles of H2O were present in the sample? How many moles of Ni(CN)2 were present? 2. Determine the empirical formula of the hydrated salt from question 1. Write your answer in the format, Ni(CN)2∙ x H2O, where “x” is an integer.
A solid sample of a complex salt, with ideal composition
Ni(NH3)6(NO3)2, was
analyzed for nickel by dissolution in slightly acidic solution and
precipitation as the dimethylglyoximate, Ni(DMG)2.
A sintered glass crucible of mass 13.2379 g was used to filter
off the precipitate. The dried crucible and precipitate had a
combined mass of 13.3319 g.
Calculate the theoretical mass of the original
Ni(NH3)6(NO3)2
sample.
0.0927 g
