Question

When Ca(NO3)2 is separated into its ions, how is it written?



Ca and NO3


Ca+2 and NO3-


Ca+2 and 2NO3-


Ca and 2NO3

Answer 1

\(\sf \huge Ca(NO_3)_{\color{red}2}\rightarrow 1~Ca^{2+}+2 ~NO_3^{-1}\)

the subscript outside of the brackets (in red) indicates the number of nitrate ions

Answer 2

it's a short form, instead of writing \(\sf \huge CaNO_3NO_3\)

Answer 3

So, what's the answer?

Answer 4

i just wrote it above.. ?
