    Hardness Water
AI Thread Summary
Water hardness can vary between floors in a building due to factors like temperature and water pressure. Warmer temperatures in lower pipes may lead to increased calcium ion reactions with bicarbonate, causing more scale buildup. Additionally, higher water pressure on the lower floors could result in more water flowing through those pipes, potentially increasing hardness. Observations of greater scale buildup on lower pipes support these conclusions, but further investigation is needed to confirm. Understanding these dynamics is crucial for addressing water hardness issues effectively.

Homework Statement



I know what causes water hardness, how it can be resolved (or dissolved - hehe), but I'm not sure why certain parts of pipes would be harder than others. Specifically, why the water on the 1st and 2nd floor of a building would be harder than that on the 3rd and 4th floor. I have to write a ten page paper on these findings, and I'm stumped. Suggestions? Possible causes?

Homework Equations



2 HCO3– → CO32– + CO2

The Attempt at a Solution



The only thing I can think of is that is may be warmer in the basement making the Ca2+ ions react with bicarbonate forming buildup.The problem is, the water from the same pipes (I assume) travels to the top floor.

HELP!

the water pressure would be higher at the bottom of the building
 
Thanks! I will add that to my paper for sure. Any more suggestions?
 
Any more ideas?

Is this a conclusion you arrived at based on the observed greater buildup of scale on the lower pipes? Is it a "safe" conclusion?

Perhaps more water is required to flow through pipes the closer they are to the level at which water enters the building?

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...
