Question
Answer the following questions or balance the following reactions (some reactions are half reactions and some reactions are full reactions): a. If you have a weak acid that has a pK_a of 4.5 and the system is strongly buffered at pH 2.0, will the molecule be primarily protonated or deprotonated? b. What is the equilibrium reaction for H_2O? C. C_6H_6 rightarrow HCO^-_ 3 d. What molecule do all cells use to pass information from one generation to the next? e. What is fermentation (fewest words)? f. Does respiration require molecular oxygen (O_2)? g. Does an oxidizer accept electrons or donate electrons? h. Does an oxidant accept electrons or donate electrons? i. Does a reductant accept electrons or donate electrons? j. Does a reducing agent accept electrons or donate electrons? k. Does an oxidizer get oxidized? I. Does a reductant get oxidized? m. Does chemical oxidation mean you add something that gets oxidized to clean up a contaminant plume in groundwater or elsewhere? n. Draw the carbonate-water buffering cycle equations starting with CO_2 gas (assume an open system): O. What is a functional group (in organic chemistry)?Explanation / Answer
(g)
An oxizer or oxidizing agent is a chemical species that undergoes a chemical reaction that removes one or more electrons from another atom. So, it accepts electrons.
(h)
An oxidant or oxidizing agent is a chemical species that undergoes a chemical reaction that removes one or more electrons from another atom. So, it accepts electrons.
(i)
Reductant is a reducing agent.
A reducing agent is an element or compound that loses (or "donates") an electron to another chemical species in a redox chemical reaction.
(j)
A reducing agent is an element or compound that loses (or "donates") an electron to another chemical species in a redox chemical reaction.
(k).
An oxidizer helps in oxidizing other reagent and gets reduced itseld.
Answer is No.
(l).
A reductant helps in reducing other reagent and gets oxidized itseld.
Answer is Yes.
(o)
Functional groups are specific groups (or moieties) of atoms or bonds within molecules that are responsible for the characteristic chemical reactions of those molecules
