AI Thread Summary
The discussion focuses on calculating the number of excess electrons acquired by a body with a static charge of -10 microcoulombs, resulting in approximately 6.2 x 10^13 electrons. To find the collective mass of these electrons, the mass of a single electron, which is 9.11 x 10^-31 kg, is used. By multiplying the number of electrons by the mass of a single electron, the total mass can be calculated. The final mass should be expressed in grams using two significant figures. This calculation illustrates the relationship between static charge and the mass of electrons involved.

On a dry day, your body can accumulate static charge from walking across a carpet or from brushing your hair.
If your body develops a charge of -10 (microcoulombs), how many excess electrons has it acquired?

N=6.2*10^13 electrons



What is their collective mass?
Express your answer using two significant figures.

m=_____g

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...
