Question

10 multiple choice 1 point use the given ion charges to determine the formula for nickel(ii) nitrate. 2+ 1- ni? (no3)? ni(no3)3 ni2(no3) ni(no3) ni(no3)2

Explanation:

Step1: Determine charge balance

Nickel (Ni) has a charge of 2+ and nitrate ($NO_3$) has a charge of 1-. To balance the charges, we need 2 nitrate ions for every 1 nickel ion.

Step2: Write the formula

The formula for nickel(II) nitrate is $Ni(NO_3)_2$.

Answer:

Ni(NO_3)_2 (last option)
