Venus is approximately 225 earth days.
When the molecule undergoes chlorination with Cl2 on heating, the hydrogen atom of the alkyl group is replaced by the chlorine atom and form chloroalkanes. The molecule X containes three types of alkyl halides, therefore three different types of chloroalkanes are formed by the replacement of hydrogem atom linked to these alkyl groups. Thus the three different types of chloroalkanes are formed - primary, secondary, and thertiary chloroalkane. Chlorination is not selective so a mixture pf products results. The products formed by the reaction of the molecule with Y with Cl2 are shown on the attached file.
Explanation:
a physical property happens with the body or something alive while a chemical property has more action with chemicals like H2O and carbon dioxide
We can prepare CaCO₃ and MgO from dolomite.

What is Dolomite?</h3>
- Common rock forming mineral is called dolomite.
- It's chemical composition is CaMg(CO₃)₂.
- The component of the sedimentary rock is called dolostone.
- It is the primary component of the metamorphic rock known as dolomitic marble.
- Limestone that contains some dolomite is known as dolomitic limestone.
Dolomite is a mineral which is rarely found in the environment , but dolostones are the minerals which are very commonly found.
<h3>Properties of Dolomite:</h3>
- The trigonal-rhombohedral system is used to crystallise dolomite
- It forms crystals that are white, tan, green, or pink in colour.
- Dolomite is a double carbonate of calcium and magnesium ions arranged in an alternating structural structure.
- Granular dolomite is a medium to dark grey, brown, or white granular dolomite found in rocks.
- The lustre varies from dull to subvitreous. Dolomite, like calcite, cleaves into six-sided polyhedrons with diamond-shaped faces.
- Dolomite vein grains may be several centimetres in diameter.
<h3>Uses of Dolomite:</h3>
- Ornamental stone is used as Dolomite, and a magnesium oxide source, as well as used in the Pidgeon magnesium production process.
- Dolomite is often used in place where calcite limestone is used as as a flux for the smelting of iron and steel when calcite limestone is not available or very expensive.
- Therefore, it is also called dolomite limestone.
- Dolomite and dolomitic limestone are often used in horticulture as a pH buffer and magnesium source in soils .
- Calcined dolomite is also used as a catalyst invery high-temperature gasification of biomass in order to kill tar.
<h3>Preparation of CaCO₃ and MgO from dolomite:</h3>
- Dolomite is a double salt which consists of calcium carbonate (CaCO3) and magnesium carbonate (MgO) and it is one of the two forms of limestone.
- This dolomite is found in the Bangkalan area, which only used in landfill and used to make light stone. Existence the great potential for dolomite as a biomaterial then in this research was carried by making CaCO3/MgO from dolomite using a simple calcination method at 600°C, 700°C and 800°C for one hour From the results of XRD found that the CaCO3/MgO phase was formed optimally at a temperature of 700°C.
Thus from the above conclusion we can say that, we can prepare CaCO₃ and MgO from dolomite.
