Answer:
Option E
RbCL<CH3OH< CH3Cl< CH4
Explanation:
The boiling temperature of an organic compound increases with the increase in number of carbon atoms and hence as the length of the hydrocarbon chain increases the boiling temperature also increase due to increase in force of attraction between the molecules. Also presence of strong molecules such as OH – COOH also increases the boiling temperature while Cl and other elements with high electronegativity reduces the boiling temperature
Hence, the correct order of increasing boiling temperature is option E
RbCL<CH3OH< CH3Cl< CH4
You will probably need more info, but it is probably accelerating and moving from one place to the next
Answer: option A) True
Explanation:
Joseph Proust is the founder of the Law of Definite proportion. This law states that two elements will always combine together to form a chemical compound and this will be in the same proportion by mass.
For Example: 2 moles of Hydrogen (H2) ALWAYS combine with 1 atom of Oxygen (O) to yield water (H2O)
So, the answer is True
Answer:
Explanation:
1. The smallest complete unit of a compound or diatomic gas
ATOM
Atoms are small tiny particles that makes up a molecule. It is regarded as the smallest indivisible particle that parts in a chemical reaction.
2. A new substance formed by the combination of two or more different atoms
COMPOUNDS
Compounds are substances composed of two or more kinds of atoms. Their properties differs from those of the constituent elements that combines to make them up.
3. Path of electrons around an atomic nucleus
SHELL
The shell describes the path of an electron round a nucleus
4. A substance consisting of only one type of atom
MONOATOMIC MOLECULE
It is an aggregate of one type of atom.
