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.

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

colorless gas, exhibiting a blue glow when placed in an electric field

b) solid

its a type of rock

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
