5) Solid silver chloride, AgCl, precipitates when solution of silver nitrate, AgNO3, and iron (111) chloride,
DanielleElmas [232]

The chemical reaction between the reactants:

3 AgNO₃ (aq) + FeCl₃ (aq) → 3 AgCl (s) +  Fe(NO₃)₃ (aq)

Explanation:

We have the following chemical reaction:

3 AgNO₃ (aq) + FeCl₃ (aq) → 3 AgCl (s) +  Fe(NO₃)₃ (aq)

Complete ionic equation:

3 Ag⁺ (aq) + 3 NO₃⁻ (aq) + Fe³⁺ (aq) + 3 Cl⁻ (aq) → 3 AgCl (s) +   Fe³⁺ (aq) + 3 NO₃⁻  (aq)

We remove the spectator ions and we get the net ionic equation:

Ag⁺ (aq) + Cl⁻ (aq) → AgCl (s)

where:

(aq) - aqueous

(s) - solid

MnO2 + 4HCl reacts to form MnCl2 + CL2 + 2H2O If .86 mol of MnO2 and 48.2 g of HCl react, which reactant is the limiting reagent
Katen [24]
HCl:
<span>
m=48,2g
M=36,5g/mol

n = m/M = 48,2g / 36,5g/mol = 1,32mol

1mol          : 4mol
MnO</span>₂        + 4HCl ⇒ MnCl₂ + Cl₂ + 2H₂O
0,86mol     :  1,32mol
                     limiting reagent 
0,33 will react

HCl is limiting reagent.

A.
Rus_ich [418]

Answer:

Multiple organisms may be affected by the loss of a plant species.

Explanation:

Organisms that feed directly off the lost plant will be affected, and because of that, organisms that feed off those organisms will be affected. This could also affect other organisms like parasites. Other plant species may be affected from the loss of a competitive species. This could affect organisms that feed off that plant, and the organisms that feed off those organisms.

What is the standard electrode potential for a galvanic cell constructed in the appropriate way from these two half-cells?

Look up the reduction potential for each cell in question on a table of standard electrode potential like this one from Chemistry LibreTexts. [1]

The standard reduction potential

resembles the electrode's strength as an oxidizing agent and equivalently its tendency to get reduced. The reduction potential of a Platinum-Hydrogen Electrode under standard conditions (

,

1.00

l

kPa

) is defined as

0

l

V

for reference. [2]

A cell with a high reduction potential indicates a strong oxidizing agent- vice versa for a cell with low reduction potentials.

Two half cells connected with an external circuit and a salt bridge make a galvanic cell; the half-cell with the higher

E

θ

and thus higher likelihood to be reduced will experience reduction and act as the cathode, whereas the half-cell with a lower

E

θ

will experience oxidation and act the anode.

E

Therefore in this galvanic cell, the

the anode.

The standard cell potential of a galvanic cell equals the standard reduction potential of the cathode minus that of the anode. That is:
