Answer:
Explanation:
Hello there!
In this case, according to the given chemical reaction, it is possible to evidence the 4:3 mole ratio between oxygen and iron (II) chloride; thus, we can compute the moles of the latter that are consumed by the given molecules of the former:
Now, since we have a 0.945-M solution of this iron (II) chloride, the corresponding volume turns out to be:
Best regards!

Answer: 2) Chloroform & Caustic potash
Explanation:
The carbylamine reaction is a kind of chemical test which is done to detect primary amines in an unknown solution. It cannot detect secondary and tertiary amines.
The reaction involves the heating with up of the unknown solution with alcoholic potassium hydroxide or caustic potash and the chloroform.
In the presence of primary amine, the production of isocyanide results.
The answer is the fourth choice, or Have membrane-bound organelles. Hope this helps you!
