Constructing balanced ionic equations

AI Thread Summary
The discussion revolves around balancing the ionic equation for the reaction involving sulfur dioxide, bromine, and water. The initial attempt suggested by the user included an incorrect number of hydrogen ions, leading to confusion about the balance of oxygen and charge. Participants emphasized the importance of ensuring that both hydrogen and charge are balanced on both sides of the equation. The user ultimately corrected their equation to include the proper coefficients, confirming that the balanced equation should be SO2 + Br2 + 2H2O ----> SO4^-2 + 2Br^-1 + 4H^+1. Accurate balancing of ionic equations is crucial for proper chemical representation.

Homework Statement


balance:
SO2 + Br2 + H2O -----> SO4 ^-2 + Br^-1 + H^+1

Homework Equations

The Attempt at a Solution


I think the answer is:
SO2 + Br2 + 2H2O ----> SO4^-2 + 2Br^-1 + 2H^+1
But the answer in the book is:
SO2 + Br2 ----> SO4^-2 + 2Br^-1
Is my answer the correct one?

Book answer can't be correct as the oxygen is not balanced.

Not that your answer is OK - count hydrogens on both sides, and see if the charge is balanced. Chances are it was just a typo on your side.

Oh yeah, sorry. It should be SO2 + Br2 + 2H2O ----> SO4^-2 + 2Br^-1 + 4H^+1. Thanks!

Thread 'Confusion regarding a chemical kinetics problem'

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...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
