When calcium carbonate is heated, it breaks down to form calcium oxide and carbon dioxide.
Thermal decomposition is the process in which heat is required.
It is also known as thermolysis.
It is processed in which a compound breaks into two or more products when the heat is supplied.
This reaction is used for the production of oxygen.
This reaction is also used for production of acidic as well as basic oxides.
CaCO3 on thermal decomposition gives:
CaCO3→CaO+CO2
CaO→ Basic oxide.
CO2→ Acidic oxide.
Molar mass is the given substance divided by the amount of that substance, measured in g/mol.
Example: titanium atomic mass is 47.88 amu or 47.88 g/mol. In 47.88 grams of titanium there is 1 mole, or 6.022 x 10^23 titanium atoms.
Answer:
The correct answer is B) both are made up of monomers that are linked by covalent bonds
Explanation:
The polymers consist of a set of monomers by covalent bonds. There are those that are natural (DNA formed by nucleotide units, proteins by amino acids, starch by glucose) and synthetics made by human hands (polyethylene formed by ethylene monomers).
Answer:
crude oil
Explanation:
<em>The substance X would be crude oil.</em>
<u>Crude oil is a non-renewable natural resource that is black and thick in appearance. It is a mixture of several products and these are often separated by a process known as fractional distillation. </u>
Some of the products from the fractional distillation of crude oil include the premium motor spirit (petrol), automotive gas oil (diesel), kerosene, etc., and derivatives for the production of dyes, paints, perfumes, etc.
