Answer: 6. 3 pairs of electron
Explanation:
A triple bond occurs when two atoms in a molecule shares 3 pairs of electron. A triple bond is also, a type of bond under the Covalent bond, which also includes, double bond and single bond.
Typically, a Covalent bond contains 2 elections. 1 from each atom. This means that, triple bond contains 6 electrons since there are three Covalent bonds, in a triple bond.
A triple bond is stronger than a single bond. It is characterized by sigma bonds between hybridized orbitals, and pi bonds between unhybridized p orbitals.
A triple bond is also vulnerable to "electron thieves". Example of compound with triple bond includes Dinitrogen, acetylene, carbon monoxide etc
Your answer would be
B. 7.3 KG
Answer:
I. a, c, f and h
II. e
III. b, d, g and i
IV. i
Explanation:
I. Chemical symbols are simple abbreviations used to represent various elements or compound. They consist entire of alphabet.
For the diagram given above, the labelled parts which represent chemical symbol are: a, c, f and h
II. Coefficients are numbers written before the chemical symbol of elements or compound.
For the diagram given above, the labelled part which represent Coefficient is: e
III. Number of atoms of element present in a compound is simply obtained by taking note of the numbers written as subscript in the chemical formula of the compound.
For the diagram given above, the labelled part which represent the number of atoms of the element are: b, d, g and i
IV. When no number is written as subscript in the formula of the element in the compound, it means the element has just 1 atom in the compound.
For the diagram given above, the labelled part which indicates that only 1 atom of the element is present is: i
Your answer would be : A transmission electron microscope
