Answer:
C(i) the elements are lead (Pb), nitrogen (N) oxygen (O). Lead is found as the Pb 2+ ion and nitrogen and oxygen form the nitrate ion NO 3 –. Its chemical formula is Pb (NO 3) 2.
C(ii) is +2 because the oxidation state of lead is +2. More Lead (II) trioxonitrate(v) is composed of lead ion and the nitrate ion.
I hope this helped
Answer:
An electric circuit is an unbroken path along which an electric current exists and/or is able to flow. ... Once one of the wires is removed from the power source or a “break” is made in the flow, the circuit is now “open” and the lamp will no longer light.

Cation</em>
When naming a chemical compound, <u>the cation</u> is written first before anything else.
A typical ionic compound consists of two components - the cation and the anion. While the <u>cation is positively charged in ion</u>, <u>the anion is negatively charged. </u>The cation of a typical ionic compound is named first before the anion and the name often carries that of the element that composes it.
The name of the element that makes up the anion is modified by removing the last few characters ending the name and replacing it with the suffix 'ide'. For example, NaCl is named sodium chloride.
The balance chemical equation is follow,
2 I⁻ + SO₄²⁻ + 4 H⁺ → I₂ + SO₂ + 2 H₂O
According to this reaction, 2 moles of I⁻ reacts with 1 mole of SO₄²⁻ to produce 1 mole of I₂ and 1 mole of SO₂.
Result:
So with the formation of 1 mole of I₂, 1 mole of SO₂ is produced.
