Answer:
Ans. C. physical change
Explanation:
Physical: boiling and melting are physical changes. When water boils no bonds are broken or formed.
Answer:
<span>Primary alcohols oxidize to form Carboxylic Acids.
Explanation:
Primary Alcohols when treated with Oxidizing agents like </span>K₂Cr₂O₇ and CrO₃<span> produces carboxylic Acids as a final product. This oxidation to Carboxylic Acid first passes through Aldehydes and then is oxidized to carboxylic Acid.
</span> As K₂Cr₂O₇ and CrO₃ are strong oxidizing agents, if a mild oxidizing agent like <span>Pyridinium Chlorochromate (PCC) is used then primary Alcohol will convert into Aldehyde.</span>
So, on reacting with strong oxidizing agent primary alcohol will produce carboxylic acids via aldehydes and when treated with mild oxidizing agent primary alcohol will produce aldehyde.

His phraseology and his turns of invention are too empirically pseudoscientific for the simplicity of nature.
<u>Answer:</u> The net ionic equation is written below.
<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 ammonium carbonate and lead (II) nitrate is given as:
Ionic form of the above equation follows:
As, ammonium 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.
