AI Thread Summary
To determine how many balloons can be inflated with a 15L helium cylinder at 165 atm, the total volume of helium available must be calculated based on the pressure and the volume needed for each balloon. Each balloon requires 2L at a pressure of 1.1 atm. The calculation involves converting the helium volume from the cylinder to the equivalent volume at the pressure required for the balloons. The approach of dividing the total helium volume by the volume needed per balloon is correct for finding the maximum number of balloons. Ultimately, the solution will reveal the total number of balloons that can be filled under the specified conditions.

Homework Statement




A cylinder containing 15L of helium gas at a pressure of 165 atm is to be used to fill party balloons . Each balloons must be filled to a volume of 2L at a pressure of 1.1 atm. What is the maximum number of balloons that can be inflated? (Hint: the empty cylinder will still contain helium at 1.1 atm)

Homework Equations





The Attempt at a Solution



I just thought of dividing the total He at the container to each balloon.

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...
