<u>Answer:</u> The net ionic equation is written above
<u>Explanation:</u>
Net ionic equation of any reaction does not include any spectator ions.
Spectator ions are defined as the ions which does not get involved in a chemical equation. They are found on both the sides of the chemical reaction when it is present in ionic form.
The chemical equation for the reaction of lead (II) nitrate and potassium sulfate is given as:
Ionic form of the above equation follows:
As, potassium and nitrate ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.
The net ionic equation for the above reaction follows:
Hence, the net ionic equation is written above.
Classify each material as an alloy or ceramic
alloy- Bronze,brass, steel and glass
Ceramic- brick and tile
<u><em> Explanation</em></u>
<u><em>Alloy</em></u> is a metal made up by combining two or more metallic elements.
for example, bronze is made up by alloying tin with copper.
<u><em>Ceramic </em></u>materials is an inorganic,non metallic which is often crystalline oxide,nitride or carbide material.
For example, Tiles are made up of natural clay sand and water.
The first one
A gas stove burner
It is basically lead oxide.. and sometimes called plumbic oxcide
it is black in colour
hope it helped
