Answer:

Pb2+ (aq) & 2Br- (aq) --> PbBr2 (s).

Explanation:

Equation of the reaction:

Pb(C2H32O2)2 (aq) + 2 NH4Br (aq) --> 2NH4C2H3O2 (aq) + PbBr2 (s)

Ionic equation:

Pb+2(aq) + 2(C2H3O2)-1 (aq) + 2(NH4+) (aq) + 2Br-1 (aq) --> 2(NH4+) (aq) + 2(C2H3O2-) (aq) + PbBr2 (s)

2(NH4)+1(aq) & 2(C2H3O2)-1 (aq) cancel out from both sides, you are left with the net ionic equation :

Pb2+ (aq) & 2Br- (aq) --> PbBr2 (s).

How many grams of potassium bromide, KBr, are in 100mL of a 0.50 M solution?
VMariaS [17]

Answer:

5.95g

Explanation:

1 dm^{3} = 1000 mL

∴ 100 mL = 100 ÷ 1000 = 0.1 dm^{3}

Volume = <u>0.1 </u>dm^{3}<u />

Concentration = <u>0.5 M</u>

Concentration = \frac{No. of moles}{volume}

0.5 = \frac{x}{0.1}

No. of moles = 0.5 x 0.1 = <u>0.05 moles</u>

No. of moles = \frac{mass}{mass. in. 1. mole}

Mass in 1 mole of KBr = 39 + 80 = 119g (39 is the mass of potassium and 80 is the mass of bromine)

0.05 = \frac{x}{119}

x = 119 × 0.05 = 5.95g

In nature, one common strategy to make thermodynamically unfavorable reactions proceed is to couple them chemically to reactions
maks197457 [2]

Answer:

31.3 kJ/mol is the free energy, ΔG, for the overall reaction, A⇌D.

Explanation:

A⇌B, \Delta G_1 = 11.9 kJ/mol  ...[1]

B⇌C, \Delta G_2= -26.7 kJ/mol  ...[2]

C⇌D, \Delta G_3= 7.30 kJ/mol  ...[3]

A⇌D, \Delta G_4 = ?...[4]

[4] = [1] - [2] - [3]  (Using Hess's law)

\Delta G_4=\Delta G_1-(\Delta G_2+\Delta G_3)

=11.9 kJ/mol - (-26.7 kJ/mol+7.30 kJ/mol)

=\Delta G_4=31.3 kJ/mol

31.3 kJ/mol is the free energy, ΔG, for the overall reaction, A⇌D.
