For the reaction below, determine the standard free energy change, δg o. cu(s) + sn2+(aq) → cu2+(aq) + sn(s) e o cell =–0.48 v v

Salsk061 [2.6K]

Answer:

92.6 kJ.

Explanation:

∵ ΔG°rxn = - nFE°cell,

Where, ΔG°rxn is the standard free energy change (J).

n is the no. of electrons in the reaction (n =2).

F is Faraday constant (C/mol) (F = 96500 C/mol).

E°cell is the standard cell potential (E°cell = - 0.48 V).

∴ ΔG°rxn = - nFE°cell = - (2)(96500 C/mol)(- 0.48 V) = 92640 J = 92.64 kJ.

Likurg_2 [28]

Answer:

grams of iron = 2262.4 g

Explanation:

The balanced chemical equation should be represented first.

2Al + Fe2O3 → Al2O3 + 2Fe

find the limiting reactants by converting to moles.

covert 1.64 kg to grams = 1640 g

moles = mass/molar mass = 1640/27 = 60.7407407407 moles

60.7407407407 × 1 mol-rxn /2 = 30.37 mol-rxn

The limiting reactant is Fe2O3 Therefore it will determine the yield of Iron

2Al + Fe2O3 → Al2O3 + 2Fe

molar mass of Fe2O3 = 56 × 2 + 16 × 3 = 112 + 48 = 160 g

atomic mass of iron = 56

mass of iron in the reaction = 56 × 2 = 112 g

moles = mass/molar mass

mass = moles × molar mass

mass = 20.2 × 160 = 3232 g

if 160 g of Fe2O3 give 112 g of iron

3232 g of Fe2O3 will give ? grams of iron

grams of iron = 3232 × 112/ 160

grams of iron = 361984 /160

grams of iron = 2262.4 g

Bas_tet [7]

A sample of material is found to have a mass if 33.03 grams (g), and a volume of 2.624 ml, hence the metal is Silver.

∴ Silver = 12.59 g/mL

The elements of group 11 (Cu, Ag, and Au) are called coinage metals because they are used in minting coins. These metals are malleable. They have the ability to get converted into sheets.

The coinage metal comprise, at a minimum, those metallic chemical elements which have historically been used as components in alloys used to mint coins.

The coinage metals have the highest electrical and thermal conductivities of all the metals, and they are also the most ductile and malleable.
