Consider a Container Of $2.0 \mathrm {~g}$ Of Hydrogen $\mathrm { H } 2$

question 94

Short Answer

Consider a container of $2.0 \mathrm {~g}$ of hydrogen, $\mathrm { H } 2$ (one mole). Suppose you removed all the electrons and moved them to the other side of the earth (Earth's radius is $6380 \mathrm {~km} , k = 1 / 4$ $\pi \varepsilon _ { 0 } = 9.0 \times 10 ^ { 9 } \mathrm {~N} \cdot \mathrm { m } ^ { 2 } / \mathrm { C } ^ { 2 } , \mathrm {~N} _ { \mathrm { A } } = 6.022 \times 10 ^ { 23 }$ molecules $\left. / \mathrm { mol } , e = 1.60 \times 10 ^ { - 19 } \mathrm { C } \right)$
(a) How much charge is left behind after you remove the electrons?
(b) What electric force do the protons exert on the electrons after they are separated as described?
