Which of the following statements are true regarding ionic compounds with polyatomic ions? a
When an alkali earth metal is attracted to a phosphate, a cation to anion ratio would be 3:2

b
Cobalt's charge is the same in CoSO4 and CoSO3

c
potassium cyanide and silver iodate are equal in cation to anion ratio.

d
An acetate can never be in an ionic compound with a cation to anion ratio of 1:3

e
Ni(SCN)2 and Au(SCN)3 have a same charge for the transition metal.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
