Two or more compounds that have same molecular formula but differ in the arrangement of atoms in molecule and thus posses different properties are known as isomers.
The molecular formula of pentane is substituting one hydrogen from pentane with bromine results in the formation of monobromo derivatives of pentane having molecular formula, .
The structure of monobromo derivatives of pentane that is 1-bromopentane, 2-bromopentane, and 3-bromopentane and having molecular formula, is shown in the image.
The other two arrangements of monobromo derivatives of pentane that is 2-bromo-2-methylbutane and 2-bromo-3-methylbutane is shown in the image.
There are different structures of monobromo derivatives of pentane having molecular formula, which contain a 4-carbon chain are 1- bromo-2-methylbutane and 1-bromo-3-methylbutane shown in the image.
The focus of Lesson 1 is Newton's first law of motion - sometimes referred to as the law of inertia. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Answer:
Hope this helps :)
Explanation:
1. A physical property is a characteristic of matter that is not associated with a change in its chemical composition.
2. Matter is everything around you. Atoms and compounds are all made of very small parts of matter.
3. Solid, liquid and, gas
4. False
5. Our weight on moon is less than it would be on Earth due to a difference of the strength of gravity on the moon.
6. Physical changes only change the appearance of a substance, not its chemical composition. Chemical changes cause a substance to change into an entirely substance with a new chemical formula. Chemical changes are also known as chemical reactions.
The Property of A Double Displacement Reaction is that the Element in front of a compound displaces the Other Metal in front of the other Compound. For eg.
BaCl2+Na2SO4=BaSO4+2NaCl
Here Barium, the metal in front of the compound BaCl2 displaces Na, the metal in front of the compound Na2SO4 to form BaSO4 and NaCl.
