AI Thread Summary
Buffers are substances that help maintain a stable pH in solutions by resisting changes in acidity or alkalinity. In biological systems, bicarbonate (HCO3-) is a key buffering agent in the bloodstream, crucial for regulating blood pH. When blood becomes too acidic, bicarbonate reacts with excess hydrogen ions to restore the pH to its normal range. This buffering action is essential for maintaining homeostasis in living organisms. Understanding buffers is important in both chemistry and biology, particularly in grade 7 science education.

The tern "buffer" is used in many products. What is a buffer? Some weak acids and bases work as a buffer system. Biocarbonate (HCO3-) is a common ion in your blood stream which acts as a buffer. Write an equation for how the pH of blood is restored to normal range when it bocomes acidic using buffering agent.

Isnt buffer a thing that neutrolizes the pH? I really need help...

Actually a buffer solution (in chemistry) resists a change in pH.. Here is a reference that offers a useful explanation.

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...
