The net ionic equation of the reaction is:
- Pb²⁺ (aq) +2 I⁻ (aq) → PbI2(s)
<h3>What are net ionic equations?</h3>
Net ionic equations are equations where ions which remain in solution known as spectator ions are not shown in the equation. Only ions involved in formation of product are shown.
In the given equation, sodium and nitrate ions are spectator ions.
The net ionic equation of the given reaction is as follows:
- Pb²⁺ (aq) +2 I⁻ (aq) → PbI2(s)
In conclusion, spectator ions are not shown in net ionic equation.

D) O-O
The higher the difference in electronegativities of the two atoms, the more polar it is. Although oxygen is a very electronegative atom, it is bonded to itself which would make it a nonpolar bond.
Answer:
Extensive properties, such as mass and volume, depend on the amount of matter being measured. Intensive properties, such as density and color, do not depend on the amount of the substance present. Physical properties can be measured without changing a substance's chemical identity.
Use coefficients of products and reactants to balance the number of atoms of an element on both sides of a chemical equation.
Answer:
71.1 mol CO2 ( 1 mol CH4 / 1 mol CO2 ) = 71.1 mol CH4 produced
