Question

From which of the following, the substance that can be further simplified by ordinary chemical means is:
i.An element or a compound.
ii.A mixture or a compound.
iii.An element of a mixture.

A.I only.
B.II only.
C.III only.
D.I and II only.
E.I, II and III only.

Answer 1

Hint: We know that the Compounds involve the chemical bonding and combination of two or more elements. These are classified as pure substances. A substance composed of two or more compounds, each of which retains its own properties is called a mixture.

Complete answer: There are many ways to classify compounds: As metallic, ionic, or covalent compounds based on the type of bonds in the molecule or as organic and inorganic compounds based on whether they have carbon and hydrogen present. The composition of a compound is fixed; the elements are always present in specific proportions. The constituent elements present in compounds can only be separated by chemical or electrochemical methods.
Whereas the constituent elements present in compounds can only be separated by chemical or electrochemical methods. The constituent elements present in compounds can only be separated by chemical or electrochemical methods. The constituent elements present in compounds can only be separated by chemical or electrochemical methods. A mixture is formed through simply mixing of elements or compounds. No new chemical bonds are formed. Mixtures can be separated using physical techniques for example filtration, chromatography, evaporation, magnetization, flotation and distillation. A mixture or a compound can give further simplification using ordinary means. A mixture can be broken into individual components. A compound can be broken into individual elements.
Therefore, the correct answer is option B.

Additional information: It can be used to cleave, producing a bright blue visualization where an antibody (otherwise another molecule), conjugated to the Beta-gal, has bonded to its target. Also, by reacting with \[Fe\left( 3 \right),\] it produces a Prussian blue colour. Therefore, it can be used as an identifying reagent for iron in laboratories.

Note:
Remember that the materials can be classified into three types: elements, compounds and mixture. Elements are substances that are made from a single type of atom. An element cannot be broken down into any other substance. These act as basic building blocks and everything in the universe is made from these.
