For the following reaction, 5.05 grams of copper are mixed with excess silver nitrate. The reaction yields 11.0 grams of copper(
andreyandreev [35.5K]

Answer:

14.9 g is the ideal yield of Cu(NO₃)₂

Explanation:

Reactants for the reaction: Cu and AgNO₃

Products: Copper nitrate and Ag

The balanced reaction is: Cu(s) + 2AgNO₃(aq) →  2Ag (s) + Cu(NO₃)₂

As the silver nitrate is in excess, the Cu will be the limiting reagent.

We convert the mass to moles → 5.05 g . 1 mol/ 63.55 g = 0.0794 moles

Ratio is 1:1, so 0.0794 moles will produce 0.0794 moles of Cupper(II) nitrate. We convert the moles to mass, and that value will be the theoretical yield.

0.0794 mol . 187.55 g /1 mol =  of Cu(NO₃)₂

You are given a sample of several compounds to separate by paper chromatography. You draw a pencil line exactly 1.00 cm from the
Pavel [41]

Answer:

a) 6.3 cm

b) 8.0 cm

c) 0.7875

Explanation:

(a) The compound has moved above upto 7.3 cm from the bottom of the paper. Let us assume that line is drawn at 1.0 cm mark as the origin of spot. \

Distance traversed by compound= 7.3 - 1.0 cm = 6.3 cm

(b) Distance traversed by the solvent = 9.0 - 1.0 cm = 8.0 cm

(c) The Rf = Compound Migration distance / Solvent front migration distance

                      = 6.3/8.0 = 0.7875
