Write the reaction to prepare C2H5Br from (image attached) a) alcohol using PX3
b) Alcohol using HX

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

answer seismograph;

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
