AI Thread Summary
To determine the grams of oxygen produced from the decomposition of 15.0 grams of H2O2, first calculate the moles of H2O2 using its molar mass. The balanced equation indicates that 2 moles of H2O2 yield 1 mole of O2, allowing for conversion from moles of H2O2 to moles of O2. After finding the moles of O2, convert this to grams using the molar mass of oxygen. Engaging in this practice will enhance understanding of mole calculations.

2H2O2---> 2H2O+O2

In the decomposition equation above, how many grams of oxygen is made when 15.0 grams of H2O2 decomposes?

6 moles of lead nitrate would create how many moles of aluminum nitrate?

I also need help with this.. i suck at moles...
 
anyone know?

You might start by determining moles. Since you say you suck at it, the practice will do you good. Show us your practice...
 
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...
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...
