given the iupac name lead(ii) nitrate, what is the correct chemical formula for this ionic compound? (nitrate ion is no₃⁻)\npb(no₃)₂\npb₂(no₃)\npbno₃\npb₂(no₃)₃\nwhen naming binary ionic compounds with metals that typically form only one type of ion, a roman numeral is always included in the name.\ntrue\nfalse
Answer
Explanation:
Step1: Determine lead ion charge
Lead(II) has a charge of +2, written as $Pb^{2+}$.
Step2: Determine nitrate ion charge
Nitrate ion is $NO_3^-$ with a charge of - 1.
Step3: Balance charges
To balance the +2 charge of lead and -1 charge of nitrate, we need 2 nitrate ions. So the formula is $Pb(NO_3)_2$.
For the second - part: Roman numerals are used to indicate the charge of metals that can form multiple types of ions. For metals that form only one type of ion, Roman numerals are not included. So the statement is false.
Answer:
- $Pb(NO_3)_2$
- False
