‼️
in j. j. thomson’s plum pudding model of the atom, the plums represent and the pudding represents
a) large neutral charged mass, large positively charged mass
b) large positively charged mass, electrons
c) electrons, large positively charged mass
d) electrons, large neutrally charged mass

answer:

c

explanation:

according to this model, the atom is a sphere of positive charge (the pudding), and negatively charged electrons are embedded in it to balance the total positive charge. the electrons are like plums in a pudding.

thats how its supposed to be

consider the reaction below.

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?
