Which of the following correctly describes the electrical charges of subatomic particles? B Protons/positive; neutrons/negative; electrons/negative

C Protons/neutral; neutrons/positive ; electrons/negative

D Protons/negative; neutrons/neutral; electrons/negative

D Protons/negative; neutrons/neutral; electrons/negative

Explanation:

There are three fundamental subatomic particles found in atom which are the protons, neutrons and electrons.

Protons are the positively charged particlesNeutrons are neutral and do not carry any chargesElectrons are negatively charged.

In the tiny central nucleus, both protons and neutrons can be found

The electrons occupy the bulk volume of the atom.

Hbr dissociates to form h+ and br-ca(oh)2 dissociates to form ca2+ and 2oh-the h+ and oh- react to form waterassuming the reactants are dissolved in water, the net reaction is h+ + oh- —> h2oif you’re asked to show all components of the reaction, the complete reaction is 2hbr + ca(oh)2 —> cabr2 + 2h2o

Answerthe half-reaction having the greatest tendency to occur at the anode:     i₂(aq) + 2e⁻  ⇄ 2i⁻  ;   e = +0.53 v======oxidation occurs at the anode. we must therefore find the half-reaction with the greatest tendency to oxidize.the given values of e are reduction potentials (the form of the half-reactions are of reduction).the lower the reduction potential, the higher the potential to oxidize. the half-cell with the lowest reduction potential will have the greatest tendency to oxidize at the anode.the half-reaction having the greatest tendency must be    i₂(aq) + 2e⁻  ⇄ 2i⁻    e = +0.53 vbecause its reduction potential is the lowest out of the three.
