Answer:
a. True
Explanation:
Molecule -
- It refers to a group of two or more than two atoms , which can exists freely on it own , is referred to as a molecule .
- The molecule is a neutral group , where the atoms are bounded by chemical bonds .
- Molecule have a characteristic property of the substance.
Hence, the given statement about molecule , is true.
The molecular formula iust is how many total number of atoms of each type are present in a molecule.
Have a close look at the structure, the large sized black atoms shown here are Carbons. Count the number of carbons, total of 5 carbons.
The smaller ones are hydrogens. Count the hydrogens they are 12.
The symbol for Carbon is C and Hydrogen is H. The molecular formula is thus C5H12.
The iupac name is Pentane
Caffeine that is C8H10N402 is molecule which made up of 4 different elements. apart from carbon the other element includes
element symbol
nitrogen N
oxygen O
hydrogen H
The number of atom present in caffeine molecule are as follows
Nitrogen=4 atoms
Oxygen=2 atoms
Hydrogen=10 atoms
