Question

Write molecular equation:
Reaction of sodium sulfide and cobalt (III) nitrate,
not sure how to do this can someone please help me break down the steps

Answer 1

Na2S + Co(NO3)3 ->

ok so lets put it in ionic form

Na+
S2-
Co3+
NO3-

now try writing what you think is on the right side of reaction arrow

Answer 2

on the right side of the equation I am just trying to balance it?

Answer 3

ok you are trying to balance what exactly when you didnt write complete equation?

Answer 4

I was thinking writing the same thing on the write side just broken down

Answer 5

then that isnt an reaction...
ok now that we have that in grip lets start over...
if we have Na2S we then know that Na has one positive charge and S has two negative charge right?
same thing with other participant Co(NO3)3, we know Co has 3 positive charge and NO3 group has one negative charge right?

Answer 6

now if Na has one positive and NO3 has one negative charge what do we get?
and if Co has 3 positive charge and S has 2 negative charge what do we get here?

Answer 7

oh so for reactions you have to have the opposite charge of the element on the other side?

Answer 8

i really dont know from where to start because thiese are basics...
do you know what atom is?

Answer 9

yes

Answer 10

ok so you know there are protons in the nucleus and electron circles the proton, there is always same amount of protons as neutrons, now if you take one electron you have atom that is positively charged right? and if you add that atom an electron it is negatively charged right?
