I think the correct answer from the choices listed above is option C. <span>Radiation, Chemical agents and Viruses may cause genetic mutations. These substances are known to have mutagenic effects to humans. As you look at MSDS of some chemical agents you can see these effects. Long exposure to radiation are said to bring this effect. Lastly, viruses can influence genetics.</span>

When a solution of NaI reacts with a solution of AgNO3, what is the net ionic equation?
Leni [432]

Answer:

Ag⁺(aq) + I⁻(aq) → AgI(s)

Explanation:

Net ionic equation is a way to write a chemical equation in which you are listing only the species that are participating in the reaction.

In the reaction:

AgNO₃(aq) + NaI(aq) → AgI(s) + NaNO₃(aq).

The ionic equation is:

Ag⁺(aq) + NO₃⁻(aq) + Na⁺(aq) + I⁻(aq) → AgI(s) + Na⁺(aq) + NO₃⁻(aq).

Now, listing only the species that are participating in the reaction:

<h3>Ag⁺(aq) + I⁻(aq) → AgI(s)</h3>

What is the chemical name for the balanced equation? 2Al+3Pb(NO3)2=2Al(NO3)3+3Pb​
Zigmanuir [339]
  • The chemical name for reactant side:

                  Al - Aluminium, Pb(NO3)2 -  Lead(II) nitrate.

  • The chemical name for product side:

                  Al(NO3)3 - Aluminium nitrate, Pb - lead.

<u>Explanation</u>:

  • This is an oxidation-reduction (redox) reaction:

                       3 Pb^{II} + 6 e- → 3 Pb^{o} (reduction)

                       2 Al^{o} - 6 e- → 2 Al^{III} (oxidation)

Pb(NO3)2 is an oxidizing agent, Al is a reducing agent.

  • Reactants:                              

                                    Al uminium

              Names: Aluminum, Aluminium powder,  Al

              Appearance: Silvery-white-to-grey powder, Silvery-white,  

                                      malleable, ductile, odorless metal.

                             Pb(NO3)2 – Lead(II) nitrate

              Other names: Lead nitrate, Plumbous nitrate, Lead dinitrate

              Appearance: White colorless crystals,  White or colorless crystals

  • Products:

                            Al(NO3)3 – Aluminium nitrate

              Other names: Nitric Aluminum salt, Aluminum nitrate,

                                       Aluminium(III) nitrate

              Appearance: White crystals, solid | hygroscopic

                                   Pb  - lead

              Names: Lead, Lead metal, Plumbum

              Appearance: Bluish-white or silvery-grey solid in various forms.

                                     Turns tarnished on exposure to air. A heavy, ductile,
