Acids and bases

AI Thread Summary

The discussion focuses on the reactions involving formic acid (HCOOH) and cyanide (CN-) as well as water (H2O) and bicarbonate (HCO3-). The first reaction, HCOOH + CN- producing HCOO- and HCN, is identified as unbalanced due to a discrepancy in hydrogen atom counts. The second reaction, H2O + HCO3- yielding H3O+ and CO3^2-, is presented as a reversible reaction. Participants seek clarification on the definitions of conjugate acids and bases, emphasizing their differences. Understanding these reactions and their balance is crucial for grasping Bronsted-Lowry acid-base theory.

Homework Statement: Hi I'm super stuck in understanding bronsted lowry theory. I understand how it supposed to function but I can't wrap my brain around it. Generally any tips and advice in helping identifying bases and acids would greatly help me.

In the attempt at a solution is my possible take on this challenge, my friend offered to check it for me and said he is certain that the second one is completely incorrect.

Translation: First equation find acid and the conjugate acid.
Second equation find the base and the conjugate base.

Relevant Equations: bronsted lowry conjugate acids and conjugate bases.

1) HCOOH + CN^- ---> HCOOH^- + HCN

2) H₂O + HCO₃^- <===> H₃O⁺ + CO3^-2

Can you quote the definition of conjugate acid and base? How do they differ?

Reaction 1 is not a balanced chemical equation (compare the number of hydrogen atoms on the left side of the reaction vs the right side of the reaction).

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
