Hello.

You can look up the course you have in your 11th and 12th standard, by looking up at the syllabus and what all are included in it. You can find the syllabus on the official website of the board or you can also get it from your school. There

Hi, the chances of you getting a fee waiver is very less. You are likely to get a reputed government College for organic chemistry. Since, the chances of getting fee remembrement you can apply for private scholarships or other scholarships that are provided in your college. If you still have

Hello Shruti

You should refer to NCERT books first for your preparation make sure you don't skip NCERT book. Most of the questions from Inorganic chemistry is directly from NCERT.

After, completing your NCERT you can refer to OP Tandon

Make sure you refer to previous year papers to get

Hello there,

Ores : When the minerals are concetrated or available in sufficient quantity for extracting economically is called an ore.

There are different types of ores like,

• Heamatite
• Magnetite
• Iron Pyrite
• Copper Pyrite
• Siderite etc..,.

There are different methods to extract an ore economically i.e., without loss.

They are,

Dear Student,

Transition elements are metallic elements that have incomplete d or f shells in the neutral or cationic states. They are called also transition metals and make up 56 of the 103 elements.  Although Sc and Y belong to the d-block, their properties are similar to those of lanthanoids.

Dear Student,

The elements in groups 3–12 as shown in the schematic periodic table are defined as the so-called d-block metals. The term transition metal is also often used to describe this group of elements.

The elements which have partially filled d-orbitals either in ground state or in one or

Dear Student,

The s-block elements are the 14 elements contained within these columns. All of the s-block elements are unified by the fact that their valence electrons (outermost electrons) are in an s orbital. The s orbital is spherical and can be occupied by a maximum of two electrons. Elements in column

Dear Student,

Metallurgy is defined as a process that is used for the extraction of metals in their pure form . Metallurgy deals with the process of purification of metals and the formation of alloys.

Principles of Metallurgy :-

• Crushing and grinding
• The concentration of ores
• Hydrolytic method
• Magnetic separation
