## anonymous one year ago 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

1. aaronq

$$\sf \huge Ca(NO_3)_{\color{red}2}\rightarrow 1~Ca^{2+}+2 ~NO_3^{-1}$$ the subscript outside of the brackets (in red) indicates the number of nitrate ions

2. aaronq

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