Answer:
Radiation
Explanation:
<u>Radiation</u> travels in energy <u>waves</u>
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)
The answer is Oxygen ions & Chloride ions. Although<span> Dissolved Oxygen (DO) can not interact with the Lead, Orthophosphates have to be added continually or the barrier breaks down. If the barrier does break down, DO combines with Lead atoms, oxidizing them. It allows Lead to drain into drinking water. Once oxidized, Lead dissolves into the water instead of sticking to the pipe. </span>Flint’s water treatment plant did not add
orthophosphates, allowing the pipes to corrode, and Lead quickly contaminated the drinking water. Additionally, Flint River water had high levels of chlorides, which accelerate corrosion.<span>
