The molecular equation :

MgI₂(aq) + Pb(NO₃)₂(aq) → Mg(NO₃)₂(aq) + PbI₂(s)

The net ionic equations

Pb²⁺(aq) + 2I⁻(aq) → PbI₂(s)

<h3>Further explanation</h3>

Given

Word equation

Required

The molecular equations and the net ionic equations

Solution

The chemical equation can be expressed in terms of:

word equation
skeleton equation
balanced equation

The equation of a chemical reaction can be expressed in the equation of the ions

When a spectator ions are removed, the ionic equation is called the net ionic equation

A molecular equation is a chemical equation that has been balanced and is written in molecular (not ionic) form

The molecular equation :

MgI₂(aq) + Pb(NO₃)₂(aq) → Mg(NO₃)₂(aq) + PbI₂(s)

the ionic equation :

Mg²⁺ +2I⁻ + Pb²⁺ + 2NO₃⁻ → Mg²⁺ + 2NO₃⁻ + PbI₂

the net ionic equations

Pb²⁺(aq) + 2I⁻(aq) → PbI₂(s)

What happens to the intensity of light emitted from stars the further away the star is from us?

Nataly_w [17]

Answer: stars vary in their effective temperature and colour. A hot star radiates more energy per second per metre surface area than a cooler star. Does this then mean that a hot star is going to appear brighter to us than a cooler one? The answer to this actually depends on a few factors

Vitek1552 [10]

Answer:

Equilibrium concentrations of Ammonia and Hhydrogen sulphide are 0.2M respectively

Explanation:

Equilibrium constant is represented by the symbol k, it may be in terms of pressure (Kp) or concentration (Kc). Equilibrium constant is the ratio of the equilibrium concentration of the products of a reaction to the equilibrium concentration of the reactants with each concentration raised to the power of its corresponding coefficients.

There are rules guiding the writing of equilibrium constant, one of them is that the equilibrium constant or concentration for pure liquid or solid is 1
