1.

The following reaction was performed:

FeBr2 + KCl → FeCl2 + KBr

  • 34 grams of iron bromide is reacted with an excess of potassium chloride to form 4.0 g of iron chloride.

Step 1 - Balance the equation (put a 1 in the blank if there is no coefficient).

FeBr2 + KCl → FeCl2 + KBr

Step 2 - Calculate the theoretical yield of FeCl2

  • Theoretical Yield of FeCl2 g - round to the nearest whole number.

Step 3 - Percent yield of FeCl2 - round to the nearest whole number.

  • Percent yield %

The following reaction was performed:

TiS + H2O → H2S + TiO

  • 20 grams of titanium sulfide is reacted with an excess of dihydrogen monoxide to form 14.9 grams of titanium oxide.

Step 1 - Balance the equation (put a 1 in the blank if there is no coefficient).

TiS + H2O → H2S + TiO

Step 2 - Calculate the theoretical yield of TiO

  • Theoretical Yield TiO g - round to the nearest tenth.

Step 3 - Percent yield of TiO.

  • Percent yield % - round to the nearest tenth.

  • 89.0 g sulfuric acid decomposes to form 7.1 g dihydrogen monoxide.

Step 1 - Balance the equation (put a 1 in the blank if there is no coefficient).

H2SO4 → H2O + SO3

Step 2 - Calculate the theoretical yield of H2O

  • Theoretical Yield g - round to the nearest tenth.

Step 3 - Percent yield of H2O.

  • Percent yield % - round to the nearest tenth.

The following reaction was performed:

Pb(NO3)2 + NaI → PbI2 + NaNO3

  • 25.2 grams of lead nitrate is reacted with 15.5 grams of sodium iodide to form 6.2 grams of sodium nitrate.

Step 1 - Balance the equation (put a 1 in the blank if there is no coefficient).

Pb(NO3)2 + NaI → PbI2 + NaNO3

Step 2 - Calculate the theoretical yield of NaNO3

  • For Pb(NO3)2 → Theoretical Yield NaNO3 g - round to the nearest tenth.

  • For NaI → Theoretical Yield NaNO3 g - round to the nearest tenth.

Step 3 - Identifying the Limiting Reagent (which reactant had the lowest TY?)

  • Limiting Reagent =

Step 4 - Percent yield of NaNO3 (calculate the % yield of the LR)

  • Percent yield % - round to the nearest tenth.
